Heat exchange is carried out, is cooled to below critical-temperature in high temperature and high pressure gaseous refrigerant, refrigerant is changed into liquid from gaseous state, and discharges
Thermal energy, realizes heating, when evaporator 4 exports high temperature and pressure liquid refrigerant, is turned on by the opposite direction of the check valve that freezes, still with
Liquid flows out.Liquid refrigerant vaporizes after variable flow restriction device throttles into condenser 3, exists into 3 refrigerant of condenser
Continue to vaporize in the space of bigger, while absorb heat, heat exchange is carried out by condenser 3 and outdoor environment, after heat exchange
Cryogenic gaseous refrigerant, then switch by four-way valve 2, sucked by compressor 1, complete heating operations, and carry out it is next with
This circulation analogized.In heating operations, it can prevent the high pressure liquid refrigerant rapid vaporization by evaporator output from reducing heating
Amount, therefore the heating energy efficiency ratio of convertible frequency air-conditioner can be effectively improved.
In summary, the refrigeration efficiency ratio of convertible frequency air-conditioner and heating energy efficiency ratio all substantially increase, it is therefore apparent that meaning
The annual Energy Efficiency Ratio for convertible frequency air-conditioner carries significantly, brings unexpected effect.
Above-described is only the preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection domain.
