Abstract

PURPOSE:To improve condensation capability and evaporate condensed water by utilizing the condensed water form an evaporator. CONSTITUTION:When dehumidification water is produced soon after operation is started, the dehumidification water is supplied to a condenser, thereby, water cooling by the dehumidification water is added to air cooling. Thereupon, the dehumidification water is heated for evaporation by the condenser. Further, in the case where a water tank is provided below the evaporator 5, and a part of piping 20 serving to feed a refrigerant from a compressor 20 to the condenser 3 is dipped in the dehumidification water accumulated in the water tank, as dehumidification water is produced soon after the operation is started, the refrigerant fed from the compressor 2 to the condenser 3 is cooled by the dehumidification water accumulated in the water tank provided below the evaporator 5 and water cooling by the cooled refrigerant is added to the air cooling. Thereupon, the dehumidification water in the water tank is heated and evaporated by hot refrigerator fed from the compressor 2 to the condenser 3.

2. Description of the Related Art As the above-mentioned air conditioner, the one shown in FIG. 4 is conventionally known (Japanese Patent Laid-Open No. 55-12305). This air conditioner has compressors 32 each provided in a case 31.
→ Condenser 33 → Capillary tube 34 → Evaporator 35 →
The refrigerant is circulated to the compressor 32, and at this time, cooling is required in the condenser 33. However, since the cooling method uses a water cooling method in which the condenser 33 is immersed in a water tank 36, the evaporator 35 A drainage facility 39 is provided to receive the generated dehumidified water and supply it to the water tank 36, and when there is little dehumidified water, tap water is made to flow into the water tank 36 via a hose 37 connected to the faucet 39. Yes, and even 36 water tanks
The hose 38 is connected to the upper side of the water tank 36 to prevent water from overflowing.

0003

[Problems to be Solved by the Invention] In the conventional case, the condenser 33 is water-cooled by being immersed in a water tank 36, so the air around the condenser 33 does not reach a high temperature, and the outside of the case 31 Since the hose 38 is provided to prevent high-temperature air from being discharged to the water tank 36 and to prevent water from overflowing from the water tank 36, there is an advantage that there is no need to discard the dehumidified water during continuous use. There are some drawbacks.

[0004] Since the hose 37 is connected to the faucet 39, it is inconvenient to move the air conditioner. ■If you forget to turn off the tap water, there is a risk that the compressor 32 will become overloaded until the dehumidified water accumulates in the water tank 36, and the overload protection device installed in the compressor 32 will be activated, making it impossible to operate. There is.

[0005] Since it cannot be used unless the water tank 36 can be drained using the hose 38, the places where it can be used are limited. The present invention was made to solve such problems, and an object thereof is to provide an air conditioner that is easy to move, can be used in any location, and can be used without any problems even if you forget to turn off the tap water. shall be.

[0006]

[Means for Solving the Problems] Claim 1 is an air conditioner that circulates refrigerant to a compressor, a condenser, and an evaporator, in which a water cooling pipe is provided around the condenser, and the pipe is provided with a pipe for cooling the evaporator. The dehumidified water generated in the condenser is supplied, and the condenser is water-cooled by the dehumidified water, and the condenser is air-cooled by a blower provided around the condenser.

[0007] According to a second aspect of the present invention, in an air conditioner that circulates refrigerant to a compressor, a condenser, and an evaporator, a part of the piping for sending the refrigerant from the compressor to the condenser is connected to the dehumidification generated in the evaporator. The condenser is immersed in a water tank provided to store water, and the condenser is cooled by the refrigerant passing through the water tank, and is also air-cooled by a blower installed around the condenser.

[0008]

[Operation] According to claim 1, when the operation is started immediately, the amount of dehumidified water generated in the evaporator is small and the condenser is air-cooled by air from the blower, but after the operation is started, the condenser is air-cooled. After some time has passed and dehumidified water is produced, this dehumidified water is supplied to the condenser, and water cooling by the dehumidified water is added to air cooling. At this time, the dehumidified water is heated and evaporated in the condenser.

According to claim 2, when the operation is just started, the amount of dehumidified water generated in the evaporator is small and the condenser is air-cooled by air from the blower, but when the operation is started, the condenser is air-cooled. After a while, when dehumidified water is generated, the refrigerant sent from the compressor to the condenser is cooled by the dehumidified water collected in the water tank, and the cooling by this cooled refrigerant is added to the air cooling. At this time, the warm refrigerant sent from the compressor to the condenser causes
The dehumidified water in the tank is heated and evaporates.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings. FIG. 1(a) is a longitudinal sectional view showing an air conditioner to which the present invention is applied. FIG. 1 shows a case, and inside the case 1, a compressor 2, a condenser 3, an evaporator 5, etc. are housed. The compressor 2 adiabatically compresses the refrigerant. This adiabatic compressed refrigerant is transferred to a pipe 20 connecting the compressor 2 and the condenser 3.
After being cooled there, it is supplied to the evaporator 5 through a pipe 21 connecting the condenser 3 and the evaporator 5, where it takes the heat of evaporation from the surroundings and converts it into air. turned into
It returns to the compressor 2 described above via a pipe 22 that connects the evaporator 5 and the compressor 2. Note that a capillary tube 4 is interposed in the middle of the piping 21. Furthermore, the case 1 is movable via casters 15 provided at the bottom.

An evaporator blower 7 is installed near the evaporator 5.
is installed. The blower 7 is for blowing the surrounding air which has been cooled by removing the heat of evaporation when the refrigerant is vaporized in the evaporator 5 as described above. Cold air is discharged from the outlet 13. A tray 8 is provided below the evaporator 5 to receive dehumidified water generated when the surrounding air is cooled.
sent to.

A condenser blower 6 is also provided near the condenser 3. This blower 6 is for cooling the condenser 3 to which the refrigerant adiabatically compressed by the compressor 2 is sent, and sucks outside air from the suction port 10.
Exhaust from the discharge port 11. Around the condenser 3, there is a
As shown in b), the pipe 18 is installed in consideration of cooling the condenser 3.
are arranged in a meandering manner, for example. This piping 18 is
As shown in FIG. 2, the interior is divided into two by a partition plate 18c made of a metal material with good thermal conductivity, and one pipe 1
8a is a dehumidified water flow pipe, and the other pipe 18b is a refrigerant flow pipe. At one end of the dehumidified water flow pipe 18a, there is a pipe 16 for sending dehumidified water from the above-mentioned receiving tray 8.
A pipe 17 for discharging dehumidified water to the dehumidified water tank 9 is connected to the other end of the pipe 18a. Further, a pipe 20 for sending refrigerant from the compressor 2 to the condenser 3 described above is connected to one end of the refrigerant flow pipe 18b, and a pipe 20 for sending refrigerant from the condenser 3 to the evaporator 5 is connected to the other end of the pipe 18b. A pipe 21 is connected thereto. In addition, piping 18
In this case, one round tube is partitioned with a partition plate 18c, and 2
The structure is not limited to a regular structure, and for example, a structure in which one tube is wound around another tube in a spiral manner may be used. The point is that heat transfer can be easily performed between the two tubes.

Therefore, the dehumidified water received in the tray 8 flows through the dehumidified water flow pipe 18a, and the refrigerant flow pipe 1
A warm refrigerant adiabatically compressed by the compressor 2 flows through the refrigerant 8b. Therefore, the condenser 3 through which the adiabatically compressed warm refrigerant passes is cooled by the cold dehumidified water from the evaporator 5 received in the tray 8. At this time, since the dehumidified water is heated by the warm refrigerant passing through the condenser 3, the dehumidified water accumulated in the dehumidified water tank 9 evaporates.

Therefore, in the case of the apparatus of the present invention, when the operation is immediately started, the amount of dehumidified water generated in the evaporator 5 is small and the condenser 3 is air-cooled by the air blown from the blower 6. After some time has passed since dehumidifying water is started, water cooling by the dehumidifying water is added. At this time, since the dehumidified water is heated by passing through the condenser 3 as described above, it evaporates. Therefore, due to this evaporation, the amount of water accumulated in the dehumidifying water tank 9 can be reduced, and the indoor air can be prevented from drying out.

FIG. 3 is a longitudinal sectional view showing another embodiment of the present invention. In this embodiment, the dehumidified water generated in the evaporator 5 is temporarily stored in a water tank 26 provided below the evaporator 5, and the dehumidified water is stored in a water tank 26 provided below the evaporator 5, and is then stored in a water tank 26 by opening a stopper 27 provided at the bottom of the water tank 26 or by pouring water into the side wall of the water tank 26. The dehumidified water is discharged to the dehumidified water tank 9 located below the water tank 26 via a hose 28 connected to a drainage through hole formed in the water tank 26 . Further, a part of the pipe 20 for sending refrigerant from the compressor 2 to the condenser 3 is immersed in the dehumidified water collected in the water tank 26. Note that the same parts as in the embodiment shown in FIG. 1 are given the same reference numerals.

Therefore, in the case of the present invention configured as described above, immediately after starting operation, the amount of dehumidified water generated in the evaporator 5 is small, and the condenser 3 is air-cooled by the air blown from the blower 6. However, when dehumidified water is generated some time after the start of operation, the refrigerant sent from the compressor 2 to the condenser 3
By passing through the water tank 26, it is cooled by dehumidified water in the water tank 26, and the cooling by this cooled refrigerant is added to the air cooling. At this time, the dehumidified water in the water tank 26 is heated by the warm refrigerant from the compressor 2 and evaporates. Therefore, due to this evaporation, the amount of water accumulated in the dehumidifying water tank 9 can be reduced, and the indoor air can be prevented from drying out.

Furthermore, in this embodiment, since a dehumidified water tank 9 is provided separately from the water tank 26, the dehumidified water can be used safely even when there is a large amount of dehumidified water, and the dehumidified water can be easily disposed of. be.

[0018]

Effects of the Invention As detailed above, in the case of the present invention, there is no need to connect a hose to the faucet, so it can be easily moved anywhere, and dehumidified water generated in the evaporator is sent to the condenser as a refrigerant. Since the dehumidified water is heated and evaporated, less dehumidified water accumulates in the dehumidified water tank, there is no need to be too careful about draining the dehumidified water, and the installation location can be used without any restrictions. Since the condenser is air-cooled by the blown air until the cooling water accumulates, this has the excellent effect of preventing operational failures caused by forgetting to take out the cooling water, which is the case in the past.
