During system work, as medium, air, as thermal source, by inputting a small amount of electric energy, drives compressor 1 to transport to coolant
OK, when its operation program is heating, First Heat Exchanger 31 and the second heat exchanger 32 as condenser, the 3rd heat exchanger 33 and space
Can heat exchanger 34 as vaporizer, during refrigeration, First Heat Exchanger 31 as vaporizer, the second heat exchanger 32 and the 3rd heat exchanger 33
As condenser, space energy heat exchanger 34 does not work, and such vaporizer absorbs heat, evaporation heat transfer cold media from surrounding
Matter, the heat transfer coolant media that this is evaporated temperature, pressure after compressor 1 rises, and through condenser radiating condensation, condensation
Coolant media afterwards through the cooling decompression of expansion valve, returns to vaporizer again by evaporation endothermic, so that coolant media is circulated back to again
Compressor 1.
During refrigeration, the gas of High Temperature High Pressure discharged by compressor 1 through air vent 11 after compressing coolant media, and described high temperature is high
It is high that body of calming the anger obtains high temperature after the 4th interface 24 of four-way change-over valve 2 enters as the 3rd heat exchanger 33 condensation of condenser
The liquid of pressure, be then passed through the 4th check valve 44, reservoir 7, the first filter 81, after the second expansion valve 52, coolant media
Flow reduces and by cooling decompression, obtains the liquid of middle temperature low pressure, then first by the second heat exchanger 32 as condenser
Heat exchange group 321 carries out heat release cooling again, obtains the liquid of low-temp low-pressure, finally flows through the First Heat Exchanger 31 as vaporizer
In coolant media temperature be significantly less than the temperature of in the air, absorb amount of heat, First Heat Exchanger 31 surrounding produces very low
Low temperature environment, reaches more preferable cooling effect.

Again after the first check valve 41, reservoir 7, the first filter 81, the first expansion valve 51, the flow of coolant media reduces and quilt
Cooling decompression, obtains the liquid of low-temp low-pressure；Then flow through as the coolant media temperature in the 3rd heat exchanger 33 of vaporizer
It is significantly less than the temperature of in the air, absorbs amount of heat, coolant media becomes the gas of middle temperature low pressure again；Finally, this middle temperature low pressure
Gaseous coolant media flow into as intensification of being absorbed heat further in the space energy heat exchanger 34 of vaporizer, and return compression
Machine 1, completes one cycle.Subsequently, system constantly circulates work, and First Heat Exchanger 31 ambient temperature improves constantly, thus
Reach preferably heating effect.It should be noted that by the setting of space energy heat exchanger 34, making coolant media obtain from the external world
To more heats (i.e. solar energy and air energy), more thermals source can be provided at low ambient temperatures for compressor, reduce pressure
The operation power of contracting machine, energy-conserving and environment-protective.
When ambient temperature is less than 5 degree, the second electromagnetic valve 62 is open-minded, and coolant media flows through the 3rd of this first bypass pipeline
During expansion valve 53, there is decrease temperature and pressure and be delivered to the second heat exchange group 322 of the second heat exchanger 32, the with the second heat exchanger 32
Coolant media in one heat exchange group 321 forms the temperature difference, and carries out heat exchange in the second heat exchanger 32, makes the coolant of main road pipeline
Medium is lowered the temperature further, and when flowing through three heat exchangers 33, coolant media temperature is significantly less than the temperature of in the air, can be low
Draw heat in warm air is such that it is able to normally heat at low ambient temperatures.Conversely, when ambient temperature is higher than 7 degree, the second electricity
Magnet valve 62 is closed, and system still normally heats.
When the delivery temperature of compressor 1 is higher than 100 degree, the 3rd electromagnetic valve 63 is open-minded, and it is second auxiliary that coolant media flows through this
During the capillary tube 10 of road pipeline, there is decrease temperature and pressure and be transferred back in the discharge chamber of compressor 1, cold with the High Temperature High Pressure after compression
Medium mixing is discharged, in order to avoid discharging, coolant media temperature is too high to lead to compressor 1 fault, affects service life of a machine.Conversely, when pressure
When the delivery temperature of contracting machine 1 is less than 85 degree, the 3rd electromagnetic valve 63 cuts out.
The ultra-low temperature cold warm air conditioner unit of the present embodiment also includes two temperature-sensitive bags, and the first temperature-sensitive bag 54 is arranged on above-mentioned four
The pipe surface that logical reversal valve 2 is connected with gas-liquid separator 9, and electrically connect with the second expansion valve 52 with the first expansion valve 51, the
Two temperature-sensitive bags 55 are arranged on the pipe surface that the second heat exchanger 32 is connected with the gas returning port 13 of compressor 1, and with the 3rd expansion valve
53 electrical connections, thus passing through the detection to this segment pipe coolant media temperature for the temperature-sensitive bag, the flow of real-time control expansion valve, balance
The temperature and pressure of coolant media in system circuit.
Preferably, described first temperature-sensitive bag 54 and the second temperature-sensitive bag 55 are critesistor.
