Hair heat absorption, produced cold reduce the liner of refrigeration equipment temperature for being close to evaporator by way of " heat conduction ", the system of low temperature
Cool equipment liner makes system by free convection, radiation (if internal have the heat exchange mode of forced convection device for forced convertion)
Confining gas cooling inside cool equipment, cryogenic gas is by free convection (if the internal heat exchange mode for having forced convection device
For forced convertion) it exchanges heat with storing, the heat of storing is taken away.Refrigeration equipment inner wall is with storing also by radiation heat transfer
Mode the heat of storing is taken away.
There are two main problems for above-mentioned cold transmittance process：First, exchanged heat to be main with air inside refrigeration equipment
Medium, since the density (1.164kg/m3,20 DEG C) and thermal coefficient (2.524 × 10-2W/ (m DEG C)) of air are relatively low,

The temperature sensing package of equipment temperature controller is placed on the pipeline of cooling cycle system and (is typically placed at evaporator pipeline exit), passes through
The temperature of evaporator exit come judge refrigerate indoor air temperature whether be reduced to setting value, the air inside refrigeration equipment
Compressor is shut down when temperature is reduced to set temperature lower limit, until the air themperature inside refrigeration equipment rises to temperature controller and sets
Compressor just turns back on work when fixed temperature upper limit.Since there are the larger temperature difference with storing temperature for air themperature, so working as
When compressor shutdown, storing temperature is not reduced to set temperature, therefore storing heat is quickly refrigeration equipment inner air
Heating, temperature are increased to compressor and turn back on work, directly result in the frequent start-stop of compressor.Cooling rate makes refrigerator-freezer slowly
Energy saving it is in urgent need to be improved, and the start and stop of compressor frequently so that the functional reliability of refrigerator-freezer declines, and greatly shortens compressor
Service life.
Currently, being changed by the forced convertion of water and storing instead of air as the water refrigeration equipment of heat exchange refrigerant using water
Heat, for heat transfer coefficient range at 1000~10000W/ (m2 DEG C), this increases the heat transfer system of refrigeration equipment to a certain extent
Number, but the inside of water refrigeration equipment must determine the utilization journey of refrigeration equipment volume with the presence of a large amount of water, the liquid level of water
