Explanation of 'cold' and 'overheating'

a cold ', is will be full of the cooled liquid through a device ( Such as the supercooler) Is cooled and method, and the full temperature under the temperature below the condensing pressure, call it too cold. Engineering, the exhaust pressure approximation as condensing pressure, exhaust pressure corresponding to the full in the difference between the liquid temperature and the condenser outlet temperature of the liquid, as the degree of supercooling. This approximation, because the pressure drop is small compared to the evaporator condenser. For air-cooled condenser, 3 ~ 5 degrees of supercooling degree is appropriate. A, 1, cut the benefits of supercooled liquid refrigerant in the process of saving the flash gas, cut the flash gas volume of specific volume, progress unit refrigerating capacity; 2, progress together back to the degree of superheat of gas, to maintain the compressor doesn't work in the wet stroke, are bound to benefit. Second, too cold in practice in the design of how to do? 1, special supercooler: with a dedicated to the supercooled equipment - Supercooler, such as the bushing, spray type may change and so on, the principle is to use less than the full of the cooled liquid temperature of cooling water cooling (again Such as deep well water) , generally comparable cooling down again before 3 ℃ ~ 5 ℃ temperature ( The super-cooling degree is 3 ℃ ~ 5 ℃) 。 2, tube and muffler heat transfer fluid for some small freon refrigeration system, although there is no specific supercooler, but the fluid for pipe insulation with muffler bandage, using low temperature drop back to the trachea for liquid temperature of the fluid in the tube, also can put a fluid for tube and direct expansion valve installed in the warehouse, the cold cold again reached intent, and then advances the refrigeration power. Together for heating the temperature of the muffler, prevent compressor suction moisture vapor and liquid impact may occur. Capillary saving of the system, capillary and muffler ( The suction) Merging together walk or welded together or hot glue methods such as condoms together. Capillary heat exchange with muffler, make save before liquid refrigerant heat exchange with the low temperature refrigerant vapor in the gas pipe on the cooling and get too cold, so the trachea can be cut back road may GaCang liquid liquid impact compressor, together and save the cold liquid refrigerant before you can reach.

With the signing of the Montreal Agreement in 1987, CFC refrigerants (such as R-11, R-12, etc.) have been completely banned due to their strong damaging effects on atmospheric ozone.
  Refrigeration network: The design of each air conditioner has the problem of how to determine the refrigerant charge, especially in the air conditioner that uses capillary tubes as throttling devices, because the capillary tubes have a higher regulating capacity The expansion valve is poor, and the change of the charge has a greater impact on its performance.
  【】Refrigerants are also called refrigeration working fluids, commonly known as refrigerants in some areas in the south.
As we all know, the power density of equipment in the computer room is high, so the volume heat is high.
  The air source heat pump is in winter heating conditions.
  【】Semiconductor cooling fins, also called thermoelectric cooling fins, are cooling devices composed of semiconductors.
   R22 and R410, which are commonly used in air conditioning and refrigeration, are two different refrigerants.
  【】In practical applications, some of the following methods are often used to detect whether the refrigerant in the refrigeration system is sufficient.
