  The storage unit 23 of the adsorber 20 stores liquid phase water as a heat medium. The storage unit 23 is provided below the adsorption unit 22 and is always in communication with the adsorption unit 22. In the adsorption mode, water evaporates from the storage unit 23 and is adsorbed by the adsorbent of the adsorption unit 22. In the desorption mode, the water desorbed and condensed from the adsorbent of the adsorption unit 22 is stored. In addition, the inside of the storage part 23 is made into the pressure reduction or a vacuum state. The storage unit 23 serves as a so-called evaporator and condenser in the heat pump.

A storage heat exchange channel 27 is provided in the storage unit 23. The stored heat exchange channel 27 is provided so as to be able to exchange heat while being isolated from the storage unit 23, and is a channel through which water as a fluid for the heat transfer medium flows. The stored heat exchange flow path 27 has an inflow port portion 28 into which medium-temperature fluid and low-temperature fluid flow in, and an outflow port portion 29 through which water after heat exchange flows out. The inlet 28 is connected to the indoor heat exchanger 16 and the radiator 14 via a valve 80 that is a switching valve, and the outlet 29 is connected to the indoor heat exchanger 16 and the radiator 14 via a valve 62 that is a switching valve. Connected with. The valves 80 and 82 are three-way valves. As shown in FIG. 5, the valves 80 and 82 are connected to the control unit 40 and controlled by the control unit 40 to communicate with the radiator 14 or the indoor heat exchanger 16. The

Next, the operation of the heat pump 10 of this embodiment will be described. When the heat pump 10 is in operation, fluids having different temperatures are supplied to the adsorption units 22 of the four adsorbers 20 to form a high temperature adsorption HA, a low temperature adsorption LA, a low temperature desorption LD, and a high temperature desorption HD. As described above, the open / close control mode is switched by the valve 50. In the high temperature adsorption HA and the low temperature adsorption LA, the adsorption unit 22 is in an adsorption mode in which water is adsorbed on the adsorbent. In the high temperature desorption HD and the low temperature desorption LD, the adsorption unit 22 is in a desorption mode in which water is desorbed from the adsorbent.

In the low temperature adsorption LA, the intermediate temperature fluid is supplied from the radiator 14 to the adsorption unit 22 from the flow path inlet 25, and the low temperature fluid is supplied from the indoor heat exchanger 16 to the storage unit 23. Here, as shown in FIG. 11, the temperature of the medium temperature fluid output from the radiator 14 is T2-1, and the temperature of the low temperature fluid output from the indoor heat exchanger 16 is T1-1. At this time, the water stored in the storage unit 23 evaporates and the evaporated water is absorbed by the adsorbent of the adsorption unit 22. When the heat of vaporization is taken away when the water evaporates, the storage unit 23 generates cold heat. Let T1-2 be the temperature of the low-temperature fluid that is output from the storage unit 23 (the stored heat exchange flow path 27) and returns to the indoor heat exchanger 16. The temperature T1-2 is lower than the temperature T1-1. If the relative pressure of the adsorption part 22 (temperature T2-1) and the storage part 23 (temperature T1-1) of the low-temperature adsorption LA is φ1, the adsorption of water in the adsorption part 22 is relative to the graph shown in FIG. The pressure can be increased up to φ1. The amount that can be adsorbed by the adsorbent is Q1.

In the high temperature adsorption HA, the medium temperature fluid that has passed through the adsorption section 22 where the low temperature adsorption LA is performed is supplied from the flow path inlet 25 to the adsorption section 22, and the low temperature fluid is supplied from the indoor heat exchanger 16 to the storage section 23. . Since the temperature of the intermediate temperature fluid that has passed through the adsorption section 22 where the low temperature adsorption LA is performed is heated by the adsorption heat in the adsorption section 22 where the low temperature adsorption LA is performed, the temperature T2- of the intermediate temperature fluid from the radiator 14 It is higher than 1. Here, the temperature of the intermediate temperature fluid that has passed through the adsorption section 22 where the low temperature adsorption LA is performed is T2-2, and the temperature of the intermediate temperature fluid that has passed through the adsorption section 22 where the high temperature adsorption HA is performed is T2-3. At this time, the water stored in the storage unit 23 evaporates and the evaporated water is absorbed by the adsorbent of the adsorption unit 22. When the heat of vaporization is taken away when the water evaporates, the storage unit 23 generates cold heat. If the relative pressure of the adsorption part 22 (temperature T2-2) and the storage part 23 (temperature T1-1) of the high-temperature adsorption HA is φ2, the adsorption of water in the adsorption part 22 is relative to the graph shown in FIG. The pressure can be increased up to φ2. The amount that can be adsorbed by the adsorbent is Q2. The relative pressure φ2 is smaller than the relative pressure φ1.

In the high temperature desorption HD, the high temperature fluid is supplied from the engine unit 12 from the flow path inlet 25 to the adsorption unit 22, and the medium temperature fluid is supplied from the radiator 14 to the storage unit 23. Here, the temperature of the high-temperature fluid output from the engine unit 12 is T3-1. As described above, the temperature of the medium temperature fluid output from the radiator 14 is T2-1. At this time, in the adsorption part 22, the water adsorbed by the adsorbent is desorbed and the adsorbent is regenerated. The desorbed water is condensed in the storage unit 23 and stored in the storage unit 23. In the reservoir 23, condensation heat is generated when water is condensed, so that the temperature of the medium temperature fluid rises. The temperature of the medium-temperature fluid that is output from the storage unit 23 and returns to the radiator 14 is T2-4 that is higher than T2-1. When the relative pressure of the adsorption unit 22 (temperature T3-1) and the storage unit 23 (temperature T2-1) of the high temperature desorption HD is φ3, the amount of water that can be adsorbed in the adsorption unit 22 (adsorption limit amount) is Q3. Thus, the water adsorbed on the adsorption part 22 is desorbed. The relative pressure φ3 is smaller than the relative pressure φ2.

In the low-temperature desorption LD, the high-temperature fluid that has passed through the adsorption unit 22 where high-temperature desorption HD is performed is supplied from the flow path inlet 25 to the adsorption unit 22, and the intermediate-temperature fluid is supplied from the radiator 14 to the storage unit 23. The temperature of the high-temperature fluid is lower than the temperature of the high-temperature fluid from the engine unit 12 because the heat is absorbed by the regeneration of the adsorbent in the adsorption unit 22 where high-temperature desorption HD is performed. Let T3-2 be the temperature of the high-temperature fluid that has passed through the adsorption section 22 where this high-temperature desorption HD is performed. Moreover, the temperature of the high temperature fluid which passed through the adsorption | suction part 22 in which low temperature desorption LD is performed is set to T3-3. As described above, the temperature of the medium temperature fluid output from the radiator 14 is T2-1. At this time, in the adsorption part 22, the water adsorbed by the adsorbent is desorbed and the adsorbent is regenerated. The desorbed water is condensed in the storage unit 23 and stored in the storage unit 23. In the storage part 23, since heat of condensation is generated when water is condensed, the temperature rises. The temperature of the medium-temperature fluid that is output from the storage unit 23 and returns to the radiator 14 is T2-4 that is higher than T2-1. If the relative pressure of the adsorption unit 22 (temperature T3-2) and the storage unit 23 (temperature T2-1) of the low temperature desorption LD is φ4, the amount of water that can be adsorbed in the adsorption unit 22 is Q4. The adsorbed water is desorbed. The relative pressure φ4 is larger than the relative pressure φ3 and smaller than the relative pressure φ1 (see FIG. 14).

The adsorption part 22 of the low temperature adsorption LA and the adsorption part 22 of the high temperature adsorption HA are in the adsorption mode. The adsorption part 22 of the low temperature adsorption LA is arranged in the adsorption loop 42 at the upstream position RS1 that is the most upstream of the input of the medium temperature fluid with the radiator 14 as a reference. The adsorption portion 22 of the high temperature adsorption HA is disposed in the adsorption loop 42 at the downstream position RS2 that is the most downstream of the input of the medium temperature fluid with the radiator 14 as a reference.

The high-temperature desorption HD adsorption section 22 and the low-temperature desorption LD adsorption section 22 have the open / close valve 30 of the individual supply path 21 connecting these reaction heat exchange flow paths 24 open, and the high-temperature adsorption HD flow path. By connecting the outlet 26 to the channel inlet 25 of the low temperature adsorption LD, the reaction heat exchange channels 24 are connected in series. As a result, a desorption loop 44 in which the high-temperature fluid circulates is formed in the order of the engine unit 12 → the high-temperature desorption HD adsorption unit 22 → the low-temperature desorption LA adsorption unit 22 → the engine unit 12 (see FIG. 11).

In the desorption loop 44, the high-temperature fluid at the temperature T3-1 is supplied from the engine unit 12 to the adsorption unit 22B, and the high-temperature fluid at the temperature T3-2 that has passed through the adsorption unit 22B is supplied from the adsorption unit 22B to the adsorption unit 22C. The high-temperature fluid at the temperature T3-3 that has passed through the adsorption unit 22C is returned from the adsorption unit 22C to the engine unit 12. The adsorption unit 22B desorbs water up to a relative pressure φ3, and the adsorption unit 22C desorbs water up to a relative pressure φ4.

The valves 80B, 82B, 80C, 82C are controlled by the control unit 40 so as to communicate with the radiator 14, and the medium temperature fluid at the temperature T1-1 is supplied from the radiator 14 to the storage units 23B, 23C. Then, the water desorbed from the adsorbent is condensed in the reservoirs 23B and 23C, and the medium temperature fluid at the temperature T1-2 heated by the condensation heat is returned to the radiator 14 from the reservoirs 23B and 23C.

  In the heat pump 10 of the present embodiment, by configuring the adsorption loop 42, the temperature difference between the temperature T2-1 of the intermediate temperature fluid output from the radiator 14 and the temperature of the intermediate temperature fluid T2-3 returned to the radiator 14 is a single adsorption unit. Compared with the case where the fluid that has undergone heat exchange with only 22 is returned to the radiator 14, it becomes larger. Therefore, more heat can be released by the radiator 14.

  Moreover, in the heat pump 10 of this embodiment, in the adsorption | suction loop 42, the temperature of the medium temperature fluid supplied to each adsorption | suction part 22 changes with the positions (order of passage of intermediate temperature fluid) of the radiator 14 and each adsorption | suction part 22. FIG. Also in the desorption loop 44, the temperature of the high-temperature fluid supplied to each adsorption unit 22 varies depending on the positions of the engine unit 12 and each adsorption unit 22. In the adsorption loop 42 and the desorption loop 44, the position of each adsorption unit 22 is sequentially switched by the control unit 40 controlling the on-off valve. Therefore, compared with the case where the temperature of the fluid passing through the adsorption part in the adsorption loop and the desorption loop is the same, the adsorbent adsorbs the adsorbent by desorbing water from the adsorbent and the relative pressure band where the adsorbent adsorbs water. The relative pressure zone to regenerate becomes wider. Thereby, the amount of reaction of the binding / desorption between the adsorbent and water can be increased and the adsorbent can be used efficiently.

  Further, in the heat pump 10 of the present embodiment, the adsorption units 22A to 22D are switched in this order between the high temperature adsorption HA, the low temperature adsorption LA, the low temperature desorption LD, and the high temperature desorption HD. That is, switching is performed in the order of the downstream position RS 2 in the adsorption loop 42 → the upstream position RS 1 in the adsorption loop 42 → the downstream position ES 2 in the desorption loop 44 → the upstream position ES 1 in the desorption loop 44. Therefore, as shown in FIG. 13, in the adsorption mode, the amount of water that can be adsorbed by the adsorbent is increased in the latter half of the first half of the adsorption mode. As a result, the adsorption unit 22 first performs an adsorption reaction at a high temperature and adsorbs water with an adsorption amount of Δq2, and then performs an adsorption reaction at a low temperature and adsorbs water with an adsorption amount of Δq1.

  Further, as shown in FIG. 14, in the desorption mode, the amount of water that can be adsorbed by the adsorbent becomes smaller in the second half than in the first half of the desorption mode. Thereby, the adsorption unit 22 is first regenerated at a low temperature to desorb water of Δq3, and then regenerated at a high temperature to desorb water of Δq4.

  By switching the mode of the adsorption unit 22 in this order, the adsorption of water by the adsorbent and the desorption of water from the adsorbent are performed in multiple stages, and the amount of adsorption / desorption between the adsorbent and water. Therefore, the adsorbent can be used efficiently.

  Further, in the heat pump 10 of the present embodiment, the valve 50 is rotated at a constant speed to control the opening and closing of the six ports, and the flow path of the water that is the heat transfer medium is switched as described above. Therefore, it is not necessary to provide a valve for each port and perform complicated control, and complicated switching can be easily performed with a simple configuration.

  In addition, although this embodiment demonstrated the example in which the storage part 23 which has the function of an evaporator and a condenser was provided for every adsorption | suction part 22, it replaced with the storage part 23 and an evaporator and a condenser were separately provided. May be provided. In this case, it is possible to use an evaporator and a condenser common to all the adsorbing units.

Further, in the present embodiment, the storage units 23A to 23D are directly connected to the radiator 14 and the indoor heat exchanger 16, and the valves 80 and 82 are provided in the outlet part 29 and the inlet part 28, respectively. The connection part similar to the suction part 22 may be used for the part 23 as well. That is, as shown in FIG. 16, a valve 70 (valve bodies 70 </ b> A to 70 </ b> D) having the same configuration as the valve 50 is provided, and the outlet 70 of the adjacent storage portions 23 </ b> A to 23 </ b> D flows through the valve 70. While connecting the inlet 28, the reservoirs 23 </ b> A to 23 </ b> D, the indoor heat exchanger 16, and the radiator 14 may be connected via the valve 70. In this case, in synchronism with the valve 50, the valve 70 is also rotated at a constant angular velocity, and the flow path of water as the heat transfer medium is switched. As a drive source at this time, the same motor 41 as the valve 50 can be used.

  Furthermore, in the present embodiment, the heat pump valve 50 including the four adsorbers 20A to 20D has been described as an example. However, the heat pump valve according to the present invention includes three or five or more adsorbers. It can also be applied to a heat pump valve provided. In this case, for each of the N adsorbers, a rotating body corresponding to the N valve bodies is arranged in a line on the same axis with a phase shifted by 360 / N degrees to constitute a valve.

In the above embodiment, the example using the adsorbent that adsorbs the heat medium as the reaction material has been described. However, in the heat pump and the cold heat generation method of the present invention, another reaction material may be used. For example, a substance that combines with a heat medium by a chemical reaction and desorbs the heat medium by a reversible reaction (for example, when water is used as the heat medium, calcium oxide (CaO), magnesium oxide (MgO), and barium oxide (BaO ), When ammonia is used as a heating medium, lithium chloride (LiCl), magnesium chloride (MgCl ₂ ), calcium chloride (CaCl ₂ ), strontium chloride (SrCl ₂ ), barium chloride (BaCl ₂ ), manganese chloride (MnCl ₂ ) , Cobalt chloride (CoCl ₂ ), nickel chloride (NiCl ₂ ), and the like. Further, hydrogen can be used as a heat medium, and a hydrogen storage alloy can be used as a reaction material.
