[Abstract]:Based on the previous research on the content of many, room temperature heat pump technology is already very mature and has been widely used, but because the water temperature is low, limiting the application range, the water temperature can be used if the side is raised to 80 DEG C, better prospects for development, the high temperature heat pump is the international development trend of heat pump, many experts and scholars at home and abroad are mostly in the water as heat source of high temperature heat pump, almost no using air as heat source and high temperature heat pump, this paper uses air as high temperature low temperature heat source heat pump water heater, it has practical value.
The refrigerant used in the experiment with mixed refrigerant, the refrigerant of certain theoretical cycle performances by equation calculation software, the condensing temperature is 85 DEG C, the evaporation temperature of 25 DEG C, considering the thermal performance and environmental protection, three as the components, quality components than by simulation the software simulation, and ultimately determine the composition ratio of A/B/C is 80%: 12%: 8%, as a mixture of experimental design. At the same time, the structure of the system and choose the equipment components, create a test prototype. In order to study the performance effects of varying operating conditions and environmental temperature on the high temperature heat pump water heater, respectively 20 C, 25 C, 30 C, 35 C, 40 C, 45 C at different ambient temperature, when the water temperature was 30 C, 40 C, 50 C, 60 C, 70 C, 80 C do the performance analysis and comparison.
The results show that the new refrigerant mixture, heating performance is good, the exhaust temperature of the compressor when the environment temperature is between 20 DEG ~40 DEG, the exhaust temperature does not exceed 110 degrees, when the ambient temperature is 45 degrees, the water temperature reaches 80 degrees Celsius, the exhaust temperature reaches the maximum value. This result is to fill the gaps in the air source heat pump in high temperature heating, high temperature heat pump performance test results are superior to the existing market. If it is used to replace the electric heating solar air conditioning system, at the same time for the two cases of operation were analyzed the economic benefit and social benefit, provide a reference for the development and promotion of the above high temperature air source heat pump, has a certain practical value.
