Description

Gas heating water heater and air source heat pump combined water supply and heating device

technical field

The utility model relates to a device for supplying hot water and heating in a living room. the

Background technique

Water heaters currently on the market include solar water heaters, electric water heaters, and gas heating water heaters. Among them, the gas heating water heater is composed of a burner, a combustion fan, a heat exchanger, a circulating water pump, a control valve, a central intelligent processor, a heating supply and return pipeline, and a domestic hot water inlet and outlet pipeline. Gas-fired heating water heaters use gas as energy. Although they can provide continuous heating, because gas is a non-renewable resource, the cost is high, and the flue gas emitted during use contains carbon dioxide and carbon monoxide, which pollutes the environment. the

At present, the world's most advanced energy-saving and environmentally friendly hot water system is an air source heat pump, also known as a heat pump water heater. It uses the reverse Carnot principle to absorb a large amount of low-temperature heat energy in the air with very little electric energy, and the heat in the low-temperature environment is transferred through the compressor. Transfer to the water heater under the high temperature environment to heat and make high temperature hot water. Therefore, it has low energy consumption and only needs to consume a small part of mechanical work (electric energy). The heat pump absorbs the air heat source to produce hot water, and the energy saving efficiency is more than 4 times that of the electric water heater. However, limited by the dependence on ambient temperature, when the temperature in winter is very low in some areas, the energy efficiency ratio of air source heat pumps decreases. Therefore, the combination of gas heating water heater and air source heat pump achieves complementary advantages, which can save energy and reduce pollutant emissions. the

Since the air source heat pump is not restricted by weather conditions such as external light in the non-heating season, it can meet the high-quality supply of hot water around the clock. In the heating season, the air source heat pump is preferentially used to exchange heat for the water in the vertical pressurized water tank, and the outdoor temperature and humidity of the air source heat pump are detected. When the COP value of the air source heat pump is low, the controller will shut down the air source heat pump The main engine starts the gas heating water heater for auxiliary heating; if the air source heat pump can fully meet the hot water demand, it can also be used for heating, at this time the intelligent controller will open the heating circulation pipeline. If the water temperature in the water tank does not reach the set requirement after the heating cycle for a few minutes, the controller will start the gas heating water heater to assist in heating the water in the water tank. In order to achieve complementary advantages, it can not only save energy, but also reduce pollutant emissions. the
