From the market application of water source heat pumps, Shenzhen in the south of China, Guangzhou to the transitional area of â€‹â€‹Shanghai, Nanjing to the northern heating areas of Beijing, Dalian and other cities in public buildings (office buildings, commercial and residential buildings, shopping malls, etc.), and residential buildings Has been widely used.
The Beijing Olympic Village uses a regenerative water source heat pump air conditioning system. It does not require a cooling tower or a boiler room. Its energy consumption is 1/4 of that of a conventional electric boiler. More importantly, it does not emit any pollutants.
As the first batch of (2006) renewable energy building application demonstration project of the Ministry of Construction, the country's largest water source heat pump residential area, the investment of 400 million yuan by Maidao Jinan developed by Hisense Real Estate, using international advanced seawater/sewage source Heat pump saves energy and reduces pollution. After completion, heating can reduce more than 20,206 tons of coal per year, and reduce carbon dioxide emissions to the atmosphere by more than 54050 tons per year. The use of seawater central air conditioning is 40% more efficient than traditional air conditioning systems, saving operation. The cost is about 40%.
According to industry insiders, water source heat pump technology is widely used in all kinds of civil buildings, public buildings, military buildings and other central air conditioning systems that need to supply hot water for heating and cooling. It also involves freezing, refrigeration and cooling in the industrial field. The process system has become an important technology for energy saving and emission reduction.
Mono Calcium Phosphate ,the chemical formula is Ca (H2PO4)2.H2O, molecular weight of the body is 252.06, after dryed the product is white or slightly yellow micro powder or granules, the relative density of 2.22 (16 Â°C). Slightly hygroscopic, soluble in hydrochloric acid, nitric acid, slightly soluble in cold water, almost insoluble in ethanol. At 30 Â°C, 100 ml of water soluble MCP 1.8g. The aqueous solution was acidic, heating the aqueous solution can get calcium hydrogen phosphate. Lose crystal water at 109 Â°C and decomposed into calcium metaphosphate at 203Â°C. Applications:Monocalcium Phosphate is used to supply mineral nutrition such as phosphorus (P) and calcium (Ca) for animal, which can be easily digested and absorbed. Extensively applied as additives of Phosphorous and Calcium in aquatic animals feed.Higher water solubility of MCP is required in aquatic animals feed.
