Describe the refrigeration system of the embodiment of the invention below in detail with reference to figure 2.
Fig. 2 is the sketch map of the refrigeration system of one embodiment of the invention.As shown in Figure 2, comprise compressor 100, heater 200, first switch unit 300, second switch unit 400 and controller 500 according to the refrigeration system of the embodiment of the invention.
Wherein, first terminals of compressor 100 (being the M lead-in wire) are connected with the N utmost point of power supply, and second terminals of compressor 100 (being the S lead-in wire) are connected with the N utmost point of power supply with inductance through parallel resistor.One end of heater 200 is connected with first switch unit 300, and the other end of heater 200 is connected with second switch unit 400 with the 3rd terminals (being C line) of compressor 100 respectively, and the resistance of heater 200 is greater than the resistance of compressor 100 main windings.One end of first switch unit 300 is connected with heater 200, and the other end of first switch unit 300 is connected with the L utmost point of power supply.One end of second switch unit 400 is connected with the 3rd terminals (being C line) of heater 200 and compressor 100 respectively, and the other end of second switch unit 400 is connected with the L utmost point of power supply.Controller 500 links to each other with second switch unit 400 with first switch unit 300 respectively, is used to control the closed and disconnected of first switch unit 300 and second switch unit 400.
Should be understood that the described power supply of the embodiment of the invention can be the alternating-current voltage source of 220V, also can be the power supply that other can supply compressor operating.
In one embodiment of the invention, first switch unit 300 and second switch unit 400 can comprise relay and switch etc.
Describe the operation principle of the refrigeration system of the embodiment of the invention in detail below in conjunction with Fig. 2.
When first switch unit, 300 closures, when second switch unit 400 broke off, as shown in Figure 2, heater 200 constituted a series loop with the main winding of compressor 100, and then the voltage at heater two ends is U
R=(R/ (R+R
CM)) * 220, wherein, R is the resistance value of heater 200, R
CMBe the resistance of the main winding of compressor 100, because the resistance R of the main winding of the long-range compressor 100 of resistance value R of heater 200
CM, then the pressure drop of heater 200 will be much larger than the pressure drop of compressor 100, and therefore, heater 200 is worked, and compressor 100 can't be worked because of pressure drop is too low.
When second switch unit, 400 closures, when first switch unit 300 breaks off, as shown in Figure 2, compressor 100 and second switch unit, 400 formation closed-loop paths, therefore, and compressor 100 work, heater 200 is not worked.
When closed and second switch unit 400 is also closed when first switch unit 300, as shown in Figure 2, compressor 100 and second switch unit, 400 formation closed-loop paths, so compressor 100 is worked.But because the electric power polarity identical (all being the L utmost point) at heater 200 two ends, so heater 200 can't be worked.
Refrigeration system according to the embodiment of the invention; Through compressor and heater are jointly controlled; Can guarantee that compressor and heater can not work simultaneously, also the situation that heater is worked all the time can not occur, the potential safety hazard of avoiding heater to work all the time and produce effectively.Simultaneously, make simply, production cost is low.
The refrigeration plant with above-mentioned refrigeration system of the embodiment of the invention is below described.
The refrigeration system that comprises casing and the foregoing description according to the refrigeration plant of the embodiment of the invention.Wherein, be limited with at least one chamber in the casing.Refrigeration system is used at least one the chamber refrigeration in the casing.
Should be understood that the refrigeration plant in the embodiment of the invention can be refrigerator, also can be other refrigeration plants such as refrigerator-freezer.
According to the refrigeration plant of the embodiment of the invention, jointly control through heater and evaporimeter refrigeration system, the potential safety hazard of avoiding heater to work all the time and produce effectively, the security performance and the service life of improving refrigeration plant, simultaneously, low cost of manufacture.
Although illustrated and described embodiments of the invention; For the ordinary skill in the art; Be appreciated that under the situation that does not break away from principle of the present invention and spirit and can carry out multiple variation, modification, replacement and modification that scope of the present invention is accompanying claims and be equal to and limit to these embodiment.
