Description
Technical field
This utility model belongs to refrigeration technology field, especially a kind of refrigeration system.
Background technology
Compression-type refrigerating system generally comprises compressor, condenser and vaporizer, and compressor is by the gaseous refrigerant of low pressure
It is compressed into the gaseous refrigerant of high pressure, the gaseous refrigerant of high pressure condenses into the liquid refrigerant of high pressure by condenser cooling,
Again the cold-producing medium of liquid is passed through vaporizer to be freezed, the cold-producing medium of liquid reenters after endothermic gasification in process of refrigerastion
Compressor.
After running a period of time, on vaporizer, meeting frosting, can affect refrigeration, sternly to traditional refrigeration system after frosting
During weight, refrigeration system will be unable to run, and at this moment needs to be defrosted, general Defrost method has two kinds, one kind is turned off power supply and is
Stop refrigeration system, allow frost naturally to melt, not only the time is longer for this method defrosting, and the temperature in refrigeration space is become
Change larger, another kind is to adopt electric heated defrosting, electric heated defrosting is a kind of typical " point " defrost, and forced heat-exchanging, is by position
In the heating tube energising of base of evaporator, vaporizer is carried out with defrost from outside to inside, main heat transfer type is convection current and spoke
Penetrate, electric heated defrosting comes with some shortcomings, first, heating tube produces heat and can disperse rapidly, and it is empty that amount of heat spreads to equipment
Between in, the rapid rising of temperature in space can be caused, if the then frequently multiple daily temperature change of food product refrigeration can cause cold
The problems of crack of jelly food, the quality of impact food, second, due to the inhomogeneities of electrical heating defrost, each defrost time
Up to 30 minutes, and need daily to carry out frequent, multiple defrost, power consumption greatly increases, and after defrost terminates about
There is the heat that 50% heating tube produces can remain in equipment, these heats can increase the load of system, affect refrigerating speed,
Further increase the power consumption of system, the 3rd, electric heated defrosting is only relatively good to the frosting elimination effect near heating tube, and
Apart from the distant place of heating tube due to inequality of being heated, also cannot be completely clear in the case that defrost set of time is 30 minutes
Remove, constantly accumulation causes the ice of system to block up fault to the residual frost that each defrost is left after terminating, and increased the fault rate of system.
Above two Defrost method all has a problem that, is not suitable for the higher system of the control accuracy requirement to temperature
Cool equipment, such as the thermal resistance dampness tester of Fabric Detection, during use, this thermal resistance dampness tester needs at an established temperature
Keep long-play, traditional refrigeration system can cannot keep constant temperature because of frosting, need to design a frost-free
Refrigeration system.
