Abstract

The present invention provides a low-temperature heating and air-conditioning system and its control method. The air-conditioning system includes a refrigerant circulation loop, the refrigerant circulation loop includes a compressor and an outdoor heat exchanger, and further includes: The refrigerant temperature adjustment device between the compressor and the compressor, when the refrigerant in the refrigerant circulation circuit circulates along the direction of the heating cycle, the refrigerant temperature adjustment device is suitable for increasing the amount of refrigerant entering the compressor temperature. The low-temperature heating and air-conditioning system and its control method provided by the present invention perform temperature compensation on the refrigerant flowing into the compressor to increase the return air temperature and return air pressure of the compressor, increase the heating capacity of the air-conditioning system, and solve the problem of low-temperature or ultra-low temperature conditions. , The air conditioner is troubled by slow heating and poor heating effect, which improves the comfort of users.

Description

Technical field [0001] The present invention relates to the field of air conditioners, and in particular, therefore relate to a low-temperature thermal air conditioning system and a control method thereof. Background technique [0002] When the existing warm air conditioner is heated, in an outdoor low temperature, ultra-low temperature environment, the air-conditioning compressor is started for a short period of time, and the refrigerant and frozen oil in low temperature state, resulting in the initial time of air conditioning started. The exhaust temperature rises too slow, the indoor heat exchanger is small in the indoor temperature difference, and it is not fast to heat, which brings us to the air-conditioning winter system, and the heating effect is not good. Inventive content [0003] The problem solved by the present invention is a problem that the existing air conditioning system is thermally improving in a low temperature system. [0004] In order to solve the above pro...
