Examples of air source heat pump systems engineering and economic and technical analysis – air source heat pumps – heat pump industry
With economic development, Energy Tensions and environmental protection has become increasingly prominent in recent years, Shanghai's many hotels have implemented the "coal to gas (oil, electricity)," environmental policies, but created a bath of hot water costs rise, we Baoshan Hotel in winter The cost of a single peak as high as 3 million yuan per day, how more and better use of natural energy, especially low-grade energy, prevent and reduce pollution, ease the energy shortage has long been a subject of concern to people. Some hotel bath water to reduce the cost of installation of the vacuum tube Solar Energy Hot water system Rely on direct sunlight to heat, is to solve the environmental problems, and reduce some of the corresponding period of the bath water costs, but nearly three years, according to the Shanghai meteorological data show that each year nearly half a year the city is cloudy and rainy days, this depends on weather conditions, or auxiliary heating pipe heating, water heating and electricity costs directly than Boiler Also high (per tonne up to 40 temperature rise more than 30 yuan), and the need to provide a large enough roof area to install lighting, there are some limitations. Solar energy is inexhaustible human nature to give clean energy, full use of its services to the production of human life, that people had long desired. Air Source Heat Pump Hot water system is the ideal potential of the sun (air can) use one of the ways that end, Peng, general manager of our hotel in a group under the leadership of the decision-making, instructed the Ministry to protect the lead manager in the whole set up by the quarter Kin-ming, the Admiralty, Yu Ming Fat, Ye Guoliang, Zhang Bing, etc. Project Technical staff of QC research team began the second half of 2004, exploration in this area.
1. Heat Pump And heat Pump Works
Heat pump technology in recent years, concern in the world of new energy technologies, currently used in reverse cycle air conditioners more. Many pump applications in daily life. Pump is an increased potential energy of the device, according to different uses have water pump, air pump, oil pump and so on. Pump is mainly to improve or increase the water level pressure; pump is to increase the pressure; pump is mainly used for oil supply systems and hydraulic equipment. People use the pump is a simple double-injection pump. These pumps are directly exposed to the material for success.
"Hot" is not material, but the energy, the existence of a broad range of quality in the nature of objects, these substances, we think the heat carrier, carriers can be solid (eg metal), liquid (water) can also be a gas. Heat transfer methods are convection, conduction and radiation. "Hot" must carry and pass through the carrier, the main transmission of different carriers in different ways. As the name suggests is the heat pump heat pump device. Under the new dictionary definition of the international refrigeration, heat pump is Condenser Release heat to heat the cooling system. Heat pump works can be divided into vapor by compression, gas compression, steam jet, absorption type, electric type, semiconductor type, and electrochemical variety. The present application should be the most common vapor compression heat pump. Its work is primarily driven by the power Compressor To heat pump in the compressor, heat exchangers, throttling device and other parts consisting of closed-loop system to cycle through the phase change working fluid state, the low-grade heat energy into high-grade heat. Low heat absorption refrigeration, high heat and heating cycles of circulation of the refrigerant has the dual effect of heating, air conditioning now used more.
Heat pump system works. Evaporator After absorbing heat, the refrigerant evaporation temperature low-pressure superheated gases generated in the compressor into high temperature and pressure by the adiabatic compression of gas condensate at constant pressure by the condenser for the low-temperature high-pressure liquid (heat of vaporization of release, while heating). Blood pressure of liquid refrigerant by throttling the low temperature low pressure liquid insulation, re-entering the evaporator, absorbing heat at constant pressure heat and evaporation into superheated steam to repeat the next cycle. Therefore, heat pump water heater using the heat released into the water, not directly generate electricity out of heat, but by heat pump water heater to heat transport into the water to go.
