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,

Reason, refrigeration equipment evaporating temperature is lower, and coefficient of performance of refrigerating (COP) is lower, and cooling rate is slower；On the other hand, it makes at present
The temperature sensing package of cool equipment temperature controller is placed on the pipeline of cooling cycle system and (is typically placed at evaporator pipeline exit), leads to
The temperature in pervaporation device exit come judge refrigerate indoor air temperature whether be reduced to setting value, the sky inside refrigeration equipment
Compressor is shut down when temperature degree is reduced to set temperature lower limit, until the air themperature inside refrigeration equipment rises to temperature controller
Compressor just turns back on work when the temperature upper limit of setting.Since there are the larger temperature difference with storing temperature for air themperature, so
When the compressor is shut down, storing temperature is not reduced to set temperature, therefore storing heat is quickly empty inside refrigeration equipment
Gas heats, and temperature is increased to compressor and turns back on work, directly results in the frequent start-stop of compressor.Cooling rate makes ice slowly
The energy saving of cabinet 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 of refrigeration equipment to a certain extent
Coefficient, but the inside of water refrigeration equipment must determine the utilization of refrigeration equipment volume with the presence of a large amount of water, the liquid level of water
Degree, while the presence of a large amount of water also increases the requirement of refrigeration equipment intensity.In addition the evaporator of cooling cycle system is placed
