Air source heat pump and combined saving 70
\"Solar water heaters and air heat pumps are a mature technology, but they had previously been \\ fragmented\\ , we adopted a set of control system, a good combination of the two, the traditional solar water heater can save 70% of electricity consumption.\" Haining Kai Solar Water Heater Co., Dayton manager Zhang Chengsong excitedly told reporters.
The air source heat pump and solar water heater \"match\" together, called \"hot water automatic control system,\" something that looks like an ordinary meter box, can it is this humble, \"gadgets\", the saving performance in a leading position.
According to the Solar Energy Industry Association, Haining Zhu Ling Xu introduced, the traditional solar water heater only in sunny sunny cold water can be heated in the event of rainy weather, the water temperature to reach the corresponding requirements. Now just heat pump \"grafted\" to the water heater, even experience a long rainy weather to cold water can be heated by heat pump. Because to 2:00 pm, water heater if the water temperature is still below 45 ?, the system will automatically start the air pump, the water temperature reached 55 ?, the system automatically shut down, and the power consumption of a traditional water heater heat pump system with auxiliary power of 30%.
Haining city, Shanghai Leather Co., Ltd. is the first company using this system, the reporter in the business to see the roof of staff quarters, 160 square meters of collector tube next to the stands four large water tanks, each tank Storage of two tons of cold water, plus the collector tube in the water, the total amount of water more than 10 tons. Such a large amount of water, only one air pump to get. Infrastructure company responsible just such an account: company previously used diesel boiler heating cold water, boiler equipment into one of 9 million; according to current prices, the monthly cost of diesel fuel burned 2.4 million a year is 288,000 yuan. If you use hot water control system, one-time investment 26 million, after a year of electricity only $ 20,000. In comparison, the latter despite higher one-time investment, but only a year, you can save 98,000 yuan. He said: \"In addition to savings, it also produced a significant reduction in air pollution due to oil.\"
