R32 DC Inverter Heat Pump for House Heating and Cooling

SolarShine Heat Pump Water Heater

In the construction industry, air to water heat pumps can be used for heating and domestic hot water supply, so as to promote building energy conservation and carbon reduction. According to the report of the International Energy Agency, the construction industry accounts for more than one third of the global final energy consumption, and its direct and indirect carbon dioxide emissions account for nearly 40% of the total. Moreover, due to the improvement of living standards in developing countries, the improvement of energy supply, the increase in the ownership and use of energy consumption equipment and the rapid growth of global building area, the energy demand of the construction industry will continue to rise.

First, heat pump water heaters are used to provide domestic hot water for buildings. With the development of urbanization, the supply of domestic hot water has become a common demand. There are three main ways to produce domestic hot water in Beijing and Shanghai: gas water heaters, electric heating water heaters and solar water heaters, which together account for more than 90% of the market share of water heating equipment, while the share of electric heat pump water heaters (mainly air energy heat pump water heaters) is very small, about 2%, the use of heat pump technology can effectively reduce carbon emissions from the preparation of domestic hot water. Although the gas water heater uses clean fuel, it still has carbon emissions, and the change of energy consumption structure of building terminals in the future is just around the corner; As the heat pump water heater system uses the environmental heat, its coefficient of performance can reach about 3, that is, one share of electric energy is input to generate three shares of heat energy, which is far better than the electric heating water heater in terms of energy utilization, thus effectively reducing carbon emissions. In addition, if the air energy heat pump water heater is combined with the solar water heater to form a solar assisted air energy heat pump water heater and other composite systems, it will have a better energy-saving performance. Therefore, in terms of domestic hot water supply, heat pump water heaters have great advantages and broad markets.
