A kind of transducer air conditioning that the utility model proposes, by the electric expansion valve of connecting with throttling arrangement, the capillary of two parallel connections that arrange in throttling arrangement simultaneously that one is long and the other is short, by corresponding solenoid control, when the air-conditioning high frequency moves, by electric expansion valve and a shorter capillary-compensated, make the normal refrigeration of air-conditioning and dehumidifying; When the air-conditioning low-frequency operation, short capillary is closed, and long capillary is opened, and at this moment electric expansion valve and long capillary throttling simultaneously further reduces evaporating temperature, makes air-conditioning reach equally the effect of dehumidifying under the low frequency state, improves the comfortableness of human body.
Description of drawings
Fig. 1 is the structural representation of the utility model transducer air conditioning preferred embodiment.
In order to make the technical solution of the utility model clearer, clear, be described in further detail below in conjunction with accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model preferred embodiment proposes a kind of transducer air conditioning, comprises the compressor 1, cross valve 9, outdoor heat exchanger 2, electric expansion valve 4, throttling arrangement 10 and the indoor heat exchanger 3 that are followed in series to form the loop, wherein:
Described throttling arrangement 10 comprises the first magnetic valve 7 of mutual series connection and the second magnetic valve 8 and second capillary 6 of the first capillary 5 and series connection mutually, described the first magnetic valve 7 after series connection and the first capillary 5 with connect after described the second magnetic valve 8 and the second capillary 6 parallel connections, the length of described the first capillary 5 is less than the length of the second capillary 6, when the air-conditioning high frequency moves, described the first magnetic valve 7 is opened, the second magnetic valve 8 cuts out, when the air-conditioning low-frequency operation, described the first magnetic valve 7 cuts out, and the second magnetic valve 8 is opened.
particularly, when the air-conditioning high frequency moves, by electric expansion valve 4 and a shorter capillary (the first capillary 5) throttling, make the normal refrigeration of air-conditioning and dehumidifying, when the air-conditioning low-frequency operation, because refrigerating capacity is less, evaporating temperature is obviously too high, make air conditioner refrigerating and dehumidifying for further reducing evaporating temperature, need to reduce evaporating temperature by long capillary, therefore, the present embodiment is than short capillary (the first capillary a 5) side long capillary (the second capillary 6) in parallel, when the air-conditioning low-frequency operation, short capillary (the first capillary 5) is closed, long capillary (the second capillary 6) is opened, at this moment electric expansion valve 4 and the second capillary 6 throttlings simultaneously, further reduce evaporating temperature, make air-conditioning reach the effect of dehumidifying, the cold wind that blows out is pleasantlyer cool, thereby improve the comfortableness of human body.
In the present embodiment, described electric expansion valve 4 is between described outdoor heat exchanger 2 and throttling arrangement 10, and in other embodiments, this electric expansion valve 4 can also be between described indoor heat exchanger 3 and throttling arrangement 10.
Above-mentioned cross valve 9 can be magnetic valve.
Below elaborate the present embodiment air-conditioner heat with refrigerating state under operation principle:
As shown in Figure 1, under refrigerating state, refrigerant flows to as shown in solid arrow in Fig. 1.When air-conditioning moves at high frequency, the first magnetic valve 7 is opened, the second magnetic valve 8 cuts out, compressor 1 rapidly will be from indoor heat exchanger 3(evaporimeter) in refrigerant suck, the refrigerant of the HTHP after compressing through compressor 1 enters and carries out condensing cooling in outdoor heat exchanger 2, become the cold-producing medium of temperature in high pressure, pass through again electric expansion valve 4 and the first capillary 5(short capillary) series connection becomes the cold-producing medium of low-temp low-pressure after throttling, arrive again indoor heat exchanger 3(evaporimeter) in evaporation, and then get back to compressor 1 the inside and compress and form a kind of refrigeration cycle.
Air-conditioning is when low-frequency operation, the first magnetic valve 7 cuts out, the second magnetic valve 8 is opened, compressor 1 rapidly will be from indoor heat exchanger 3(evaporimeter) in refrigerant suck, the refrigerant of the HTHP after compressing through compressor 1 enters and carries out condensing cooling in outdoor heat exchanger 2, become the cold-producing medium of temperature in high pressure, pass through again electric expansion valve 4 and the second capillary 6(long capillary) series connection becomes the cold-producing medium of low-temp low-pressure after throttling, arrive again indoor heat exchanger 3(evaporimeter) in evaporation, and then get back to compressor 1 the inside and compress and form a kind of refrigeration cycle.Because the second capillary 6 is longer, coordinate electric expansion valve 4 throttlings further to reduce evaporating temperature, make air-conditioning be issued to the effect of dehumidifying at low frequency.
Heating under state, refrigerant flows to as shown in dotted arrow in Fig. 1.when air-conditioning moves at high frequency, the first magnetic valve 7 is opened, the second magnetic valve 8 cuts out, compressor 1 rapidly will be from outdoor heat exchanger 2(evaporimeter) in refrigerant suck, the refrigerant of the HTHP after compressing through compressor 1 enters and carries out condensing cooling in indoor heat exchanger 3, become the cold-producing medium of temperature in high pressure, first through the second capillary 5(short capillary) after again through becoming the cold-producing medium of low-temp low-pressure after electric expansion valve 4 series connection throttlings, arrive again outdoor heat exchanger 2(evaporimeter) middle evaporation, and then get back to compressor 1 the inside and compress and form one and heat circulation.
air-conditioning is when low-frequency operation, the first magnetic valve 7 cuts out, the second magnetic valve 8 is opened, compressor 1 rapidly will be from outdoor heat exchanger 2(evaporimeter) in refrigerant suck, the refrigerant of the HTHP after compressing through compressor 1 enters and carries out condensing cooling in indoor heat exchanger 3, become the cold-producing medium of temperature in high pressure, first through the second capillary 6(long capillary) after again through becoming the cold-producing medium of low-temp low-pressure after after electric expansion valve 4 series connection throttlings, arrive again outdoor heat exchanger 2(evaporimeter) middle evaporation, and then get back to compressor 1 the inside and compress and form one and heat circulation.Because capillary 6 is longer, coordinate electric expansion valve 4 throttlings can further promote the heating capacity of air-conditioning under low frequency.
