A refrigerant suitable for air source heat pump water heater

Abstract

The invention discloses a refrigerant suitable for an air source heat pump water heater, including refrigerant R134a, R417a and R407, which has passed the national environmental protection product quality supervision and inspection, and has an ozone depletion potential value ODP (<0.11, international standard ODP≤0.11) , purity 99.99%, moisture 0.001%, evaporation residue 0.0012%, acidity: not detected, appearance, colorless and transparent, no peculiar smell, low system pressure when the machine is running, low operating power consumption, high heating capacity, reaching above COP5.1 Energy efficiency: It is a high-temperature and low-pressure environmentally friendly refrigerant, especially adding cesium oxide as a catalyst, which can significantly improve the heating energy efficiency ratio of the refrigerant.

Description

technical field [0001] The invention relates to the field, in particular to a refrigerant suitable for an air source heat pump water heater. Background technique [0002] With the continuous improvement of people's living standards, water heaters have become a necessity in people's lives. According to the Market Economy Research Institute of the Development Research Center of the State Council ((2004-2006 China Urban Water Heater Market Research and Consultation Report), in the next five years, the market capacity can reach 50 billion yuan per year. As the fourth generation of water heaters, heat pump water heaters, It is popular for its advantages of good safety, energy saving, and environmental friendliness. The operating characteristics of air source heat pump water heaters depend to a certain extent on the characteristics of refrigerants. Therefore, choosing a suitable refrigerant can greatly improve the performance of air source heat pump water heaters. But at present,...

Problems solved by technology

However, at present, most heat pump water heaters still use the traditional refrigerant R22, and the "Montreal Protocol on Substances that Deplete the Ozone Layer" stipulates that for R22 refrigerants, developed countries must completely eliminate them before 2020, and developing countries must ban them all by 2030.
