We can work with you to find total solutions to your energy requirements, perfect solution for your heating/cooling/hot water requirements

Air source heat pumps (ASHPs) absorb heat from the outside air to heat your home and hot water. They can still extract heat when air temperatures are as low as -15°C. ... If you have large garden space outside, you could consider a ground source heat pump.

Pros And Cons Of Air Source Heat Pumps Air To Water HVAC Heating System

The air source heat pump water heater is mainly composed of a compressor, a heat exchanger, an axial fan, a heat preservation water tank, a water pump, a liquid storage tank, a filter, an electronic expansion valve and an electronic automatic controller. After the power is turned on, the axial flow fan starts to run, and the outdoor air passes through the evaporator for heat exchange. The air after the temperature is lowered is discharged from the system by the fan. At the same time, the working fluid inside the evaporator absorbs heat and vaporizes and is sucked into the compressor. A low-pressure working fluid gas is compressed into a high-temperature, high-pressure gas and sent to the condenser. The water forced to circulate by the water pump also passes through the condenser. It is heated by the working medium and sent to the user for use. The working medium is cooled into a liquid, and the liquid is expanded After the valve is throttled and cooled, it flows into the evaporator again, and it works repeatedly in this way. The heat energy in the air is continuously "pumped" to the water, so that the temperature of the water in the heat preservation tank gradually rises, and finally reaches about 55°C, which is just suitable for people to take a bath.
. Air source heat pump is one of the most advanced energy utilization products in the world today. With the rapid economic development and the improvement of people's quality of life, domestic hot water has become a necessity for people's daily life. However, traditional water heaters (electric water heaters, fuel oil and gas water heaters) have disadvantages such as high energy consumption, high costs, and serious pollution; The operation of energy-saving and environmentally-friendly solar water heaters is restricted by meteorological conditions. The heating principle of the air source heat pump is completely different from the traditional solar water heater. The air source heat pump uses air, water, solar energy, etc. as the low temperature heat source, and the air source heat pump uses electric energy as the power to draw heat from the low temperature side to heat the domestic water, and the hot water is circulated. The system is directly sent to the user as a hot water supply or a fan coil unit is used for heating in a small area. Air source heat pump is the best solution for large, medium and small hot water centralized supply systems in school dormitories, hotels, bathing centers and other places.
