The invention discloses an accurate
temperature control refrigeration system. The
system comprises an internal regulation
system and an external induction module. According to the precise temperaturecontrol
refrigeration system, firstly, the external temperature is taken as a
frequency conversion temperature, and an overall air conditioner can enter a low-frequency state only after the external temperature reaches a set range, the air conditioner cannot enter the low-frequency state in advance, and accurate
temperature control of the air conditioner is achieved; secondly, during
refrigeration, the exhaust temperature of a compressor can be effectively reduced, refrigeration efficiency is improved, time for adjustment of the change of the external temperature is shortened, time for coolingis shortened, the temperature is more stable, and the effect of accurate
temperature control is achieved during refrigeration; finally,
frost on an external
heat exchanger can be melted during heating, an
air conditioning system needs no reverse by a four-way valve during
defrosting,
heating efficiency of an
air conditioning heat pump is greatly improved, and the
air conditioning system performsheating during
defrosting synchronously. Therefore, comfort of the air conditioning in heating is improved, and better use prospect is provided.
