Problems solved by technology

For example, the binary mixed refrigerant R32 / R125 applied for in U.S. Patent 4.978. 467 may be a mixed refrigerant with practical value, but the existing mixed refrigerant is only suitable for a certain range of applications and has relatively large limitations because the refrigerant has its own
[0005] Due to its fixed characteristics and scope of application, no mixed refrigerant can be applied to different evaporation temperature regions and condensation temperature regions at the same time, and the refrigerants introduced in the existing literature have limited energy-saving effects in refrigeration, heat pump and air-conditioning equipment. Generally, it is 5-10%; in addition, the use of existing refrigerants often requires more modifications to the original refrigerants, heat pumps and air-conditioning equipment before it can be applied, which will bring many difficulties to practical application and promotion

Abstract

The invention relates to an energy-saving environment-friendly mixed refrigerant. The energy-saving environment-friendly mixed refrigerant consists of CH2F2(R32), CHF2CF2(R125), CH2FCF3(R134a) and / orCHF2CHF2(R134), CH3CH=CH2(R1270). The mixed refrigerant does not damage an ozone layer, is relatively low in greenhouse effect coefficient, extremely good in environment acceptability and excellent inthermal physical and chemical properties, can be used as refrigerant to substitute for R22 and R502 to be widely applied to air conditioners, heat pumps and refrigeration apparatuses, and can save the energy by 30 to 45 percent when used in the air conditioner and heat pump apparatus; when the mixed refrigerant is used in the refrigeration apparatus, the energy can be saved by 25 to 45 percent; and meanwhile, the mixture can also be used as a heat transfer medium, a spray-type propellant, a foaming swelling agent, an electric insulation substance, a power circulating working medium, a cleaning solution, a solvent and the like.

Description

technical field [0001] The invention mainly relates to engineering technical fields such as heating, refrigeration, thermal power, etc., and in particular relates to an energy-saving and environment-friendly multi-element mixed refrigerant suitable for air conditioners, heat pumps and refrigeration devices. Background technique [0002] As we all know, in traditional refrigeration and heat pump devices such as air conditioners, refrigerators, and refrigerators, halogenated hydrocarbons obtained from alkane series derivatives are usually used as refrigerants. In the prior art, chlorodifluoromethane (CHCIF 2 , R22, boiling point -40.8°C) and R502 (an azeotropic mixture composed of R22 and R115) have been widely used as refrigerants in refrigeration devices such as air conditioners, freezers, and refrigerators; at the same time, halogenated hydrocarbons are also widely used in fire fighting , cleaning, production of foam polymers and other fields. [0003] However, in recent y...
