The air source heat pump hot water project works according to the "reverse Carnot" principle. Simply put, the "outdoor unit" compresses air like an air pump, raising the temperature of the air, and then conducts heat to the indoor water storage tank through a liquid that will boil at -17 ℃, and then releases and conducts the heat to the water. Simply put, it absorbs heat from the air to heat the water temperature, and the absorbed heat is used in the kitchen to solve the problem of stuffiness. Using the working principle of a heat pump for heating, it is the opposite of air conditioning for cooling - the national cooling standard is 1000 watts, and electric cooling is 2800 watts.
According to the principle of thermal equilibrium, a minimum of 2800 watts of heat is generated simultaneously, and with the input of 1000 watts of electricity, the actual heat generated is between 3000-4000 watts. Transporting this heat to the insulated water tank consumes only a quarter of the electricity of an electric water heater (even if the thermal efficiency of an electric water heater is 100%, the input of 1000 watts of electricity only produces 1000 watts of heat). Air source heat pump hot water projects do not require sunlight, so they can be placed at home or outdoors. After the water stored in the solar water heater is used up, it is difficult to produce hot water immediately.
If electric heating requires a long time, while air source water heaters can operate under pressure 24 hours a day as long as there is air and the temperature is above zero degrees Celsius. In this way, even after using one tank of water, another tank of hot water will be produced in about an hour. At the same time, it can fundamentally eliminate safety hazards such as electric water heater leakage, dry burning, and harmful gases generated during the use of gas water heaters. It overcomes the disadvantages of solar water heaters being unusable and inconvenient to install on rainy days, and has many advantages such as high safety, high energy saving, long service life, and no toxic gas emissions. The lifespan of an air source water heater can generally reach 15 to 20 years.
