Problems solved by technology

At present, heat pump systems using HCFC22 or its substitutes R407c, R410a, etc. as the working fluid are widely used, and the maximum temperature of hot water that can be provided is 50-55°C (no matter how high it is, it will not only deteriorate the cycle performance, but also cause the system to break through. The upper limit of pressure and exhaust temperature will cause harm), unable to provide heat energy of higher temperature grade

Abstract

The invention relates to a high-temperature heat pump mixed working medium. In a first scheme, the mixed working medium comprises the composition in the percentage by weight: 50-90% of HCFC-124 (chloride-1,2,2,2-tetrafluoroethane) and 10-50% of HCFC-142b (chloride-1,1-difluoroethane). The high-temperature heat pump mixed working medium of the invention is friendly to environment, has favourable thermal performance, can satisfy the using requirements of medium-high temperature heat pump systems of which the condensing temperature is 70-105 DEG C.

Description

technical field [0001] The invention relates to a high-temperature heat pump mixed working fluid. Background technique [0002] For civil heating and industrial production processes, such as well washing in oil field production, heating of crude oil transportation, heating of bath liquid in electroplating production, heating in printing and dyeing and textile production, they have relatively low requirements for thermal energy grade (temperature is 60-100 ℃), the use of heat pump heating technology not only has a higher total energy utilization efficiency than conventional energy supply methods, reduces CO2 emissions (thus reducing the greenhouse effect), but also effectively utilizes industrial waste heat, geothermal energy, solar energy and the environment. The low-grade heat energy contained in (air, soil, surface water or shallow groundwater) reduces thermal pollution caused by waste heat discharge. At present, heat pump technology is developing towards medium-high temp...
