Kind Code:
A1
Abstract:
Disclosed in the present utility model is a refrigeration system having accurate temperature control, comprising: a compressor, a condenser, an electronic expansion valve, an evaporator, a drying filter, a sight glass, a temperature sensor, a pressure sensor and a pressure switch, and being characterized in that the number of channels in the evaporator is two or three, the two channels respectively being a hot air bypass channel and a refrigerant channel; the compressor, the pressure switch, the condenser, the drying filter, the sight glass, the evaporator, the temperature sensor and the pressure sensor are successively connected in series to form a closed refrigerant loop, the refrigerant loop passing through the refrigerant channel of the evaporator; an exhaust port of the compressor is connected by means of the hot air bypass channel to the end of the electronic expansion valve close to the sight glass; a hot air bypass penetrates through the hot air bypass channel; and the hot air bypass is provided with a hot air bypass valve. The refrigeration system having accurate temperature control operates stably, exhibits more accurate temperature control, and is not prone to temperature fluctuation.
