Heat pump water heater is a new type of hot water and heating heat pump product, which is a heating equipment and hot water device that can replace boilers. Compared to traditional solar energy, heat pump water heaters can not only absorb heat from the air, but also absorb solar energy. The heat pump water heater absorbs heat through refrigerant temperature difference and compresses heat with the compressor, exchanging heat with water, greatly improving thermal efficiency and fully utilizing new energy. It is a new type of water heater that perfectly combines the advantages of electric and solar water heaters.
There are three series of heat pump water heaters: air source heat pump water heater, water source heat pump, and solar energy type, which are one of the best equipment for exploring and utilizing new energy. According to different heat sources, heat pumps can be divided into air source heat pumps, water source heat pumps and geothermal heat pump.
Air source (solar) heat pump is one of the most advanced products in the world today. The product uses refrigerant as the medium, and the refrigerant absorbs energy from the air (or sunlight) in the fan coil unit (or solar panel). After being compressed and heated by the compressor, the heat is transferred to the water supply through a heat exchange device to produce hot water. The hot water is sent to the user's radiator through a water circulation system for heating or directly used for hot water supply.
Principle of heat pump hot water unit:
The heat pump hot water unit follows the law of conservation of energy and the second law of thermodynamics. By using the principle of heat pumps, only a small portion of mechanical work (electrical energy) needs to be consumed to transfer the heat in a low-temperature environment (atmosphere or groundwater, etc.) to a high-temperature water heater for heating to produce high-temperature hot water. A heat pump can be compared to a water pump, where water cannot spontaneously flow from low to high. To transport water from low to high, a water pump must be used to consume a portion of electricity in order to deliver water to a high water tank. Similarly, according to the second law of thermodynamics, heat cannot spontaneously transfer (transfer) from a low-temperature environment to a high-temperature environment. To achieve this goal, a machine must consume a portion of mechanical work (such as electrical energy) in order to transfer heat from a low-temperature environment to a high-temperature environment. Such a machine is called a 'common heat pump'.
The function of a heat pump is to extract heat from air or low-temperature water, along with the heat energy converted from the electrical energy used, and send it to a high-temperature environment for application.
