Background technique
The cooling capacity transmittance process (heat transfer process is in contrast) of refrigeration equipment at present: the refrigerant in evaporator steams
Hair heat absorption, produced cooling capacity reduce the liner of refrigeration equipment temperature for being close to evaporator by way of " thermally conductive ", the system of low temperature
Cool equipment liner makes to make by free convection, radiation (if the internal heat exchange mode for having forced convection device is 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 and storing are also by radiation heat transfer
Mode the heat of storing is taken away.
There are two main problems for above-mentioned cooling capacity transmittance process: first is that being inside refrigeration equipment take air as main heat exchange
Medium, since the density (1.164kg/m3,20 DEG C) and thermal coefficient (2.524 × 10-2W/ (m DEG C)) of air are lower,
Cause heat transfer coefficient low；Two kinds of (refrigeration equipment inner wall in storing the temperature difference range) changes second is that free convection and radiation heat transfer

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 decline the functional reliability of refrigerator-freezer, greatly shorten compressor
Service life.
Currently, being changed instead of air as the water refrigeration equipment of heat exchange refrigerant by the forced convertion of water and storing 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
