Problems solved by technology
Based on the limitations of various and related factors and conditions, the use of electric defrosting cannot maximize the electric heating power to achieve the ideal effect of timely defrosting or timely and rapid thawing, so it is difficult to further improve the heating effect of heat pump air conditioners in winter, which restricts Vigorously develop, promote and apply large-scale heat pump air conditioners
[0010] The disadvantage of electric heating defrosting is that because of the safety of leakage electricity, the conductor part used for electricity must be isolated by insulating packaging so as to be isolated from other metal parts of the air-conditioning system, so it is determined that the electric heating part and the frosting part cannot be closely connected. Close to bonding and deployment, so it is difficult to achieve fast and effective defrosting

This invention is an air conditioner with improved heating efficiency and to two-temp. energy-saving. It comprises compressor, super-cooling liquid producer, four-way valve set, heat exchanger, throttle valve and control valve, and over-heated delay release set. The compressor is connected with super-cooling liquid producer. The overheated delay release set is connected with four-side valve, and the valve set also connected with indoor heat exchanger and outdoor heat exchanger. The other end of outdoor heat exchanger is connected with control valve, throttle valve, super-cooling liquid producer, and liquid collector. The other end of indoor heat exchanger is connected with another control valve; throttle valve, liquid collector and super-cooling liquid producer to make a closed circulating device.
Description
1. Technical field: [0001] The invention belongs to an air conditioner for electrical appliances. 2. Technical background: [0002] At present, most of the known large-scale air conditioners can only be used for cooling and cooling. Conventional heat pump air conditioners have poor heating and heating effects in winter, and are prone to frost and freeze, which affects the heating and heating effects. It is difficult to use heat pump air conditioners alone for direct heating and heating. Overwintering, when the outside temperature is low, only auxiliary electric heating (pipe or wire) can be used as a supplementary heat source or to defrost. The use of electric auxiliary heat sources for heating and heating is expensive and wasteful; moreover, the defrosting time of electric heating is long, the efficiency is low, the effect is poor, and the measurement and control is difficult; thus directly affecting the heating and heating effect of the heat pump air conditioner.
