air source heat pump water heater
The air source heat pump water heater is the working principle of the use of a compression heat pump equipment, mainly evaporator, compressor, condenser and expansion valve four-part composition of the working fluid through the completion of the constant evaporation (environmental lessons in the heat) → → compression condensate (heat off) → → cut further evaporation of the heat cycle, so the environment will be transferred to heat water, heat pump at work, the environmental media stored energy in the QA evaporator be absorbed; it Their consumption of energy, that is, the compressor power QB; working fluid through the circulatory system in the condenser carried out in the heat QC, QC = QA + QB, which can be seen that the output of energy for heat pump compressor power QB do And the environment to absorb heat from the heat QA; As a result, use of heat pump technology can save a lot of power. Heat pump technology with the history of the development of the industrial revolution, in the early 19th century, people will be able to lower the temperature of the heat from the media "pump" to a higher temperature of the media on this issue have taken place in interest. British physicist JPJoule made "by changing the pressure of compressible fluids will be able to make a change in temperature" principle. In 1854, W. Thomson, a professor (that is well-known Lord Lord Kelvin) published papers, a multiplier of heat (Heat Multiplier) concept, for the first time described the idea of absorption heat pump air in the low-calorie, through the middle of the media The exchange of heat and compressed into a high-temperature gas pipeline through the circulatory system for water heating, electric water heater power consumption is only 1 / 4. The new products to avoid relying on a solar water heater and installation of the hot sun to adopt the shortcomings of inconvenience. As the air heater to work through the heat exchanger medium, so the electric heating elements do not come into contact with water, not the risk of leakage electric water heater, gas water heaters are not likely to risk of explosion and poisoning, not to mention fuel emissions caused by the water heater Air pollution. Heat pump at work, the environment, energy storage medium Q air source heat pump water heater is the working principle of the use of heating, air conditioning and refrigeration on the contrary - the national standard refrigeration is 1000 W 2800-watt electric refrigeration. According to the principle of heat balance, at least at the same time generate 2,800 kilowatts of energy, together with the input of 1,000 watts of electricity, he actual heat generated in the 3000-4000 watt, these heat transfer to the water tank insulation, and its power consumption is only one-fourth of the water heater (Even if the water heater thermal efficiency of 100%, type 1000-watt electric only 1,000 watts of heat). Air source water heaters do not need the sun, so at home or on the outside can be. Solar water heaters save water are used up, it is difficult to produce hot water again soon. If the electricity and heating will take a long time, as long as the water heater and air air source, the temperature at -7 degrees Celsius to 43, can run 24 hours a day under pressure. As a result, even if run out of a box of water (60 liters), about half an hour and then it will have a box of hot water. At the same time, it can also eliminate the electric water heater leakage, as well as dry gas water heater when the use of harmful gases such as security, solar water heaters to overcome the rainy days can not be used to install and inconvenience, and other shortcomings, high security, high-energy, long life No gas emissions and many other advantages. Air source water heaters can be life-expectancy of 15-20 years.
