The R290 and R22?

now, heat pump water heater company is given priority to with R22, the goods accounted for about 80% of the total industry, and the rest of the goods first choose everything, R410A R32, with companies such as haier, will source separation in the residential and commercial market launched a few choose CO2 refrigerant commodity.

as we have learned, midea, haier, gree, such as the trunk stream of heat pump water heater brand in the field of environmental protection refrigerants instead of homework had to undertake an 'orderly'. The United States of 2015 first choose r410a and everything listed on the heat pump water heater. Gree heat pump water heater with R410A series products are now to the market. Guangdong thermal cubic heat pump first engaged in the export affairs, about European customers, first choose everything hot cubic heat pump water heater.

from heat pump water heater refrigerant alternatives to see in the world, Japan's main CO2, main R290 countries in Europe and Australia, the United States tend to be more center.

02。 R290 is suitable for small power commodity

used in heat pump water heater, the flammability of R290 make produce company must think of the problems of filling amount, R290 used there will be limitations on heat pump water heater. Now, the industry comparison recognition idea is R290 is suitable for small power heat pump water heater, and in the use of large commercial heat pump hot water machine is limited. Now the Chinese market didn't finish the R290 heat pump water heater production.

03。 CO2 in the short term is difficult to commercial

compared with other refrigerants, CO2 many advantages such as environmental protection, access to capital, haier heat pump water heater development department is very bullish on the use of CO2 in the heat pump water heater category vision. According to introducing, choose CO2 refrigerant heat pump water heater is competition of three big advantage: it is appropriate cryogenic condition, for example, in - 25 ℃ can normal heating; Second, the heating capability is strong, the water temperature higher than 80 ℃, can lower the tank volume, processing limited user device; Three is the high temperature is very appropriate commercial, industrial, printing and dyeing industry in particular.

about the CO2 refrigerant on the heat pump water heater to widespread commercial use, the important factors concerned personage thought 'high pressure CO2 make commodity price drop, drop in the heat pump water heater market competition force. 'CO2 as refrigerant of heat pump water heater, the whole machine operation operation pressure is very high, request all the piping in the goods bearing weight to 300 kg, is 10 times higher than the existing request, to all parts of the goods put forward higher request. Now the domestic market of form a complete set of CO2 heat pump water heater upstream parts companies such as compressor, throttle valve is very less, cause the cost of CO2 heat pump water heater is very high and pose a safety hazard, and the goods can be in the future the main commodity on the market now is good, so many companies are not willing to take this step. 'Of beauty, will switch to the CO2 refrigerant heat pump water heater does not exist skills difficulties, from the beginning of 2009 start the development work of beauty, and launch special compressor using CO2 heat pump water heater. Now, the chief problem of the CO2 heat pump water heater is a commodity itself offer is too high, is almost 3 times the general heat pump water heater, can't do commercial success. '
