Description of Student Dormitories Hybrid Water Heater Large Scale Central Hot Water System:
A special rain cover for water pumps is adopted, which includes a waterproof surface and a fixing belt. The outer upper end of the waterproof surface is connected with a plurality of adhesive tapes and hairy surfaces, and the surroundings of the waterproof surface are connected with rain lugs. Several fixing straps are connected to one side of the waterproof surface. The bottom side of the fixing belt is bonded with an adhesive tape hook surface, the side where the waterproof surface is connected to the fixing belt is provided with a number of perforations, the outside of the fixing belt is clamped with a fixing frame, and one end of the fixing belt is from the perforation The inside of the locating bolt passes through and is connected to the fixing frame, the top of the perforation is connected with a threaded positioning bolt, and the bottom end of the positioning bolt abuts the fixing belt. The installation and disassembly of the waterproof surface and the water pump is convenient and quick, which improves the work efficiency. At the same time, the rain cover can be used for rain protection of water pumps and rain protection of other small parts, with a wide range of applications and strong application performance. The rain cover has a simple structure and is easy to disassemble and assemble. A rain cover can be applied to a certain range of water pumps and has a wide range of applicability.
Application of air source heat pumps
Air Source Heat Pump Air Conditioning provide house heating and hot water,wherever need hot water, energy saving and more economical, not feel dry,it is widely use in hospital,sauna,factory,commercial centre,slaughter, swimming pools, spas, etc
The air source heat pump water heater is a heat pump water heater that uses air as a low temperature heat source to produce domestic hot water. It is mainly composed of an air source heat pump circulation system and a water storage tank. The air source heat pump water heater is a device that produces hot water by consuming part of the electric energy and transferring the heat in the air to the water. In recent years, CO2 heat pump water heaters have been studied at home and abroad. Under the condition of the evaporation temperature of 0℃, heating the water from 9℃ to 60℃, the COP value of the CO2 heat pump hot water system can reach 4.3. When the ambient air is used as the heat source, the annual operating average heating COP value can reach 4.0, which can save 75% of energy compared with traditional electric heating or coal-fired boilers.
