Embodiment Construction
[0015] The following combined examples and instructions are attached to the present invention further.
[0016] like figure 1 It is shown that the refrigeration compressor exhaust heat and the spray -to -jet -tojet -coupled of the decorative refrigeration circulation system., Slotal valve, gas liquid separator, evaporator, jet, liquid supercharged pump, liquid level controller, solenoid valve, pressure sensor, temperature sensor, etc.
[0017] Its refrigeration cycle method is:
[0018] The saturated liquid refrigerant after condenser condensation is divided into two roads. After the throwing valve, the throttling valve and cooling down the voltage, and the other road passes through the liquid supercharged pump to enter the three -channel generator.The start -up and stop of the pressure pressure pump is controlled to achieve the purpose of controlling the liquid level of the three -channel generator.
[0019] When the system starts, start the high temperature level first. Due to t...
