【 Weak current College 】 heat pump hot water unit structure and principle

Working principle
Use of equipment in thermal media (refrigerant) from the air or in the acquisition of the natural environment and, through the heat exchanger in the cold water rapidly raised temperature, while emissions from air-conditioning. To avoid the traditional solar products in rainy weather, night work, as long as the outside temperature is-15 ℃ above to work correctly, it can be more efficient, energy saving, and may not account for open space, the installation of a simple, flexible.
Units constitute operating modes and principle
Heat pump hot water unit is composed by a refrigeration cycle, including the host and the condenser. Which host portion including evaporator, fans, compressors and expansion valve; condenser condensation to put inside coil insulation box. Refrigerants in the evaporator heat absorption outside air through the heat pump in condensing coil in the release of heat, heat the water in the water tank. Water tank insulation with obturator rubber sponge or polyurethane foam, and has good insulation properties.
Heat pump equipment specifically reset an endothermic medium – refrigerant, liquefied state at room temperature below minus 20 degrees Celsius, so that there is a difference in the outside temperature, refrigerant absorbed outside temperature, in the evaporator inside pressure and evaporation vaporization, heat exchanger (heat pump), the refrigerant from the vaporization of the State into a liquid state, the objective existence of heat is released to water reservoir of water use. Electric only used at the heat energy released, and not in the direct heating, electricity, very few, in summer the temperature is high, producing a loss of about 5 tons of hot water — 6 unit, the winter cold weather about loss of 20-25 degrees of electricity, the annual average of no more than 15 degrees.
The characteristics of the product
Heat sources, including the Sun, the rain water and air. Regardless of the day, night, regardlessof the sunny cloudy, windy or rainy, snow can work as usual, is not affected by the climate impact, 24/7 all year round work as usual;
Can be placed anywhere you specify, without affecting the appearance of buildings, with little space, without direct lighting, the installation is very easy. You can open display, also can be placed in the inconspicuous corner or to the library, and can realize unmanned operation, automatic control temperature water supply;
Application range is extensive: it can be used for hotel, restaurant, factory, school, hospital, sauna, beauty salon, swimming pools, greenhouses, farm, laundries, family, etc., can be used separately, may be set using the different heating requirements, you can choose a different product lines and installation design, as well as free access air from any angle to meet your requirements;
Excellent insulation CFC-free, only 2% of heat loss, can be more time to maintain the water temperature, thermal efficiency than other conventional solar product indeed. Non-freon refrigerant, no emissions, wastewater discharge, absolutely no environmental protection, water tank gas or electric drive, absolute security.
Energy-saving effect is clear, and the use of fuel oil, gas, electricity, coal, etc., you can save at least 75 percent of the cost of running, allowing you to easily recover costs.
Product characteristics
High efficiency energy-saving: the air is not hot water unit to produce hot water and low temperature heat source, the power consumption of only for electric water heaters-1/3; 1/4 with coal, oil, gas hot water unit can be saved compared to 75 per cent of the running costs.
Environmental pollution: the system is running without any combustion and emissions, is a sustainable development of environmentally friendly products.
Run the secure and reliable: the entire system running non-conventional water heater (fuel or gas or electric water heater) possible flammable, explosive, toxic, dangerous, such as short circuit is a secure and reliable hot water system.
Long service life and low maintenance. Comfortable and convenient, automated, intelligent degree high.
