There is a large amount of 30 DEG C to 60 DEG C of residual heat resources in industrial production, often directly discharged, cause energy wave
Take and environmental pollution.A kind of important means of the heat pump as energy recovery, can be converted to the low-phase energy in low-temperature heat source
High potential, it is directly used in the industrial production of requirements at the higher level, on the one hand improves energy utilization rate, be on the other hand significantly reduced
Energy waste and environmental pollution.Have widely for normal temperature heat pump of the condensation temperature less than 60 DEG C on domestic market
Use, but there has been no breakthrough in the research of moderate and high temperature heat for pursuing higher leaving water temperature (reach 100 DEG C and more than)
Progress.Wherein key reason is to lack the excellent refrigerant of a kind of environment-friendly, safety and stability, cycle performance.Conventional use
In refrigerant such as CFC113, CFC114, CFC11 of high temperature heat pump etc., ODP values and GWP value are larger, while damaging the ozone layer
Greenhouse effects are exacerbated, it is worldwide disabled, and such as HFC134a, HCFC22, have under worst hot case too high
Condensing pressure and compressor exhaust temperature and can not normal use.Meet that environment-friendly, safety and stability, cycle performance are excellent simultaneously
Novel refrigerant that is good, adapting to worst hot case is high temperature heat pump technology key issue urgently to be resolved hurrily.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of HFC-245fa/HFC-134a
Application of the mix refrigerant in high temperature heat pump.
To achieve the above object, the technical solution adopted by the present invention is：
Application of the HFC-245fa/HFC-134a mix refrigerants in high temperature heat pump, by HFC-134a, HFC-245fa two
Kind constituent element carries out physical mixed at normal temperatures by the quality proportioning specified, and can directly charge turns into high temperature heat pump in source pump
Unit, produce 70-110 DEG C or so of hot water.
Further, the HFC-134a accounts for percentage 0-60%, HFC-245fa and accounts for percentage 40-100%.
After said structure, beneficial effects of the present invention are：
(1) leaving water temperature is high：The mix refrigerant of the present invention can be charged directly in common HFC-134a source pumps, no
The lubricating oil of replacing unit is needed, more than 70-110 DEG C of hot water can be produced.
(2) security and stability is good：Two kinds of components in the present invention will not react between each other, and can with including
Material contact including copper, steel, refrigeration oil, pad, motor insulating layer, rubber, plastics etc. is protected without any reaction occurs
Having demonstrate,proved it being capable of safe and stable operation.
(3) worst hot case cycle performance is good：The present invention is under 50 DEG C of evaporating temperatures, the operating mode of 100 DEG C of condensation temperatures, root
Different according to component ratio, heating COP is all higher than 3.59, and unit volume heating capacity is all higher than 3143.2kj/m3, unit mass heating
Amount is all higher than 123.26kj/kg, and cycle performance is good.
