Air energy heat pump is to use the heat in the air to generate heat energy, can 24 hours a day, high water pressure, constant temperature to provide the whole family with different hot water, heating and cooling needs, and at the same time to consume the least energy to complete the above requirements.
The principle
Air energy heat pumps operate on the "reverse Carnot" principle, the reverse Carnot cycle principle. Operating through a compressor system, it absorbs heat from the air to produce hot water. The specific process is: the compressor compresses the refrigerant, the temperature rises after compression, and the refrigerant passes through the condenser in the tank to produce hot water. The refrigerant after heat exchange returns to the compressor for the next cycle. In this process, the air heat is absorbed into the refrigerant through the evaporator, and the refrigerant is introduced into the water to produce hot water. Air heat pump water heater is a new generation of water heater which is heated by compressor air. Metaphorically speaking, the "outdoor machine" compresses the air like a 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 ° C, and then releases heat to the water.
The heat pump works on the principle of heating, as opposed to air conditioning refrigeration - the national refrigeration standard is 1000 watts, and electric refrigeration is 2800 watts. According to the principle of heat balance, at least 2800 watts of heat is generated at the same time, plus the input of 1000 watts of electricity, the actual heat generated in 3000- 4000 watts, the heat is transported to the insulated water tank, its power consumption is only a quarter of the electric water heater (even if the thermal efficiency is 100%, the input of 1000 electricity is only 1000 watts of heat).
Air-powered water heaters do not require sunlight, so they can be placed at home or outside. Therefore, most of the manufacturers of the machine have a separate machine and a machine, solar water heater storage after the water is used up, it is difficult to immediately produce hot water. If the electric heating takes a long time, and the air heater as long as there is air, the temperature is above zero degrees Celsius, it can operate 24 hours a day under pressure. In this way, once a tank of water is used, another tank of hot water will be produced in an hour or so. At the same time, it can fundamentally eliminate the electric water heater leakage, dry burning and gas water heater when the use of harmful gas and other safety hazards, overcome the solar water heater overcast and rainy days can not be used and installation inconvenience and other shortcomings, with high safety, high energy saving, long life, no gas emissions and many other advantages. Air energy water heaters generally have a life span of 10 to 15 years.
The installation
Air energy heat pump is usually installed in the kitchen balcony, the outlet is linked to the kitchen through the air duct, so that the cold air blown out can directly enter the kitchen, to achieve the effect of refrigeration. When installing, only the cold and hot water mouth and the house reserved cold and hot water link, can be used, the installation is very simple, but the effect is not too good.
