Heat pump principle

The definition heat pump is a device that can obtain low-grade heat energy from natural air, water or soil, and work through electric power to provide high-grade heat energy that can be used by people.

The heat pump is essentially a heat boosting device. The heat pump is used to extract heat from the surrounding environment and transfer it to the heated object (higher temperature object). The working principle is the same as that of the refrigerator. The difference between the working and the Carnot cycle is that the operating temperature range is different.

When the heat pump is working, it consumes a part of the energy itself, excavates the energy stored in the environmental medium, and uses the heat transfer medium circulation system to increase the temperature, and the whole heat pump device consumes only a small part of the output work. Therefore, the use of heat pump technology can save a lot of high-grade energy.

The heat pump is a refrigeration system that supplies heat from the condenser to heat it. It is called a “heat multiplier”. At present, heat pump heating has been widely applied to household heating and cooling air conditioners widely appearing on the market, and the heating coefficient thereof has been as high as three or more. Then, the principle of heat pump is used to make hot water, and the hot water obtained by one degree of electricity is consumed more than the hot water obtained by the ordinary electric water heater, which is unmatched by the conventional water heater.

Basic principle The basic principle of heat pump water heater: it is mainly composed of compressor, heat exchanger, axial flow fan, heat preservation water tank, water pump, liquid storage tank, filter, electronic expansion valve and electronic automatic controller. After the power is turned on, the axial fan starts to operate, the outdoor air exchanges heat through the evaporator, and the air after the temperature is lowered is exhausted by the fan. At the same time, the internal combustion fluid of the evaporator is sucked into the compressor, and the compressor will The low-pressure working gas is compressed into a high-temperature, high-pressure gas and sent to the condenser. The water forced to be circulated by the water pump also passes through the condenser, is heated by the working medium and sent to the user for use, and the working medium is cooled into a liquid, and the liquid is expanded. After the valve throttles to cool down, it flows into the evaporator again. After repeated cycles, the heat energy in the air is continuously “pumped” to the water, so that the water temperature in the insulated water tank gradually rises, and finally reaches 55 °C, which is just suitable for people to take a bath. It is the basic working principle of air source heat pump water heater.

Anti-corrosive Primer

â… Description:

Anticorrosive Primer consist of a mixture of butyl rubber and synthetic compound and a solvent-gasoline. The Liquid adhesive is quickly drying applied to the appropriately prepared pipe surface before application of inner layer tape. The function of Liquid adhesive is to provide a bonding medium between the pipe surface and the inner layer tape. It is suitable for hand brush or machine spray application. It can be applied by hand or machine.
