Household air conditioning refrigerants, air conditioning refrigerant _ are described in detail

Household air conditioner generally use which kinds of refrigerant? Commonly used household air conditioning refrigerant has everything, R22, R407C, r410a.

R22 refrigerant introduction

R22 is a kind of freon refrigerant in the application, mainly used in household air conditioner and cryogenic refrigerator. The thermodynamic properties of R22 similar to ammonia. Standard gasification temperature is - 40. 8 ℃, condensing pressure usually not more than 1. 6MPa。 R22 non-combustible, not burst, safe and reliable in use than ammonia. Unit volume of R22 about 60% higher than R12, the unit volume when the capacity at low temperature and saturation pressure are higher than R12 and ammonia. In recent years of large air-conditioning chiller refrigerant mostly to replace everything.

main use: refrigerant R22 as today's most widely used in low temperature, is mainly used in household air conditioner, commercial air conditioning, central air conditioning, mobile air conditioning, heat pump water heater, dehumidifier, frozen type dryer, cold storage, food refrigeration equipment, Marine refrigeration equipment, industrial refrigeration, commercial refrigeration, refrigeration condensing units, supermarket display cabinets and other refrigeration equipment.

refrigerant R407C introduction

physicochemical properties: under atmospheric pressure, R407C is a chlorine fluoroalkane non azeotropic mixed refrigerants, colorless gas, storage is compressed in the cylinder of liquefied gas. The ODP 0

and therefore is not damage of atmospheric ozone layer environmental protection refrigerant R407C.

main use: R407C is mainly used to replace R22, clean, low toxic, non-combustible, refrigeration effect is good wait for a characteristic, a large number of used in household air conditioner, small and medium-sized central air-conditioning.

R410A refrigerant is introduced

physicochemical properties: under atmospheric pressure, R410A is a chlorine fluoroalkane non azeotropic mixed refrigerants, colorless gas, storage is compressed in the cylinder of liquefied gas. The ODP 0

so R410A the ozone layer is not to undermine the atmosphere environmental protection refrigerants.

main use: R410A is mainly used to replace R22, r114

, with clean, low-toxic, non-flammable, refrigeration effect is good wait for a characteristic, a large number of used in household air conditioner, small commercial air conditioning, household central air conditioner, etc.

R134a( Four fluorine ethane) Refrigerant is introduced

everything is internationally recognized as substitute R12

one of the main refrigerating agent, commonly used in automotive air conditioning, commercial and industrial refrigeration system, and used as a foaming agent in hard plastic insulation materials production, can also be used to configure other mixed refrigerants, such as r404a and R407C

and so on.

main use: the main substitute R12 used as refrigerant, used in automobile air conditioning and refrigeration.

home air conditioning refrigerant R22 and R410A contrast

R22 properties: colorless at room temperature, the approximate tasteless gas, not burning, explosion, corrosion, toxicity than R12 slightly larger, but is still a safe refrigerants, security classification for A1; Pressure can be liquefied colorless transparent liquid. Chemical stability and thermal stability of R22 are very high, especially in without the presence of moisture, can't afford to under 200 ℃ and general metal reaction. In water, only with alkali slow work. It happens in high temperature cracking. Refrigerant R22

is a kind of low temperature, can be obtained The refrigeration temperature of 80 ℃.

R410a used in frequency conversion air conditioning. It is a new kind of environmental protection refrigerants, does not destroy the ozone layer, the pressure of work for the common R22 air conditioner 1. Refrigeration (about 6 times, Warm) High efficiency,

improve the performance of air conditioning does not destroy the ozone layer.

R410a features: new refrigerant R410a is composed of two kinds of quasi azeotropic mixture of R32 and R125 each 50%, mainly include hydrogen, fluorine and carbon ( Said for HFC) , has the stability, non-toxic, superior performance, etc. At the same time as a result of not containing chlorine, so will not react with ozone, which does not destroy the ozone layer.

in addition, the adoption of new refrigerant air conditioning in terms of performance also will have certain to improve. R410A is by far the most appropriate internationally recognized to replace R22 of refrigerant, and in Europe and the United States, Japan and other countries. R410A replacement in the main international market of global trends and prospects of using condition and the dynamic of entering the international market.

what kind of model is more than half the household air conditioning related introduction, note that air conditioning refrigerant charging must be according to the type of air conditioning on filling, avoid the damage in air conditioning system.

Everyone who has a start capacitor suppliers wants it to look start capacitor suppliers. However, in order to achieve that, it normally involves investing in a start capacitor suppliers air conditioner capacitor. Hangzhou E cool refrigeration Co.,Ltd can offer you the best solution.
