Features of Low Ambient Temperature Operation Air Source Heat Pump for Hotel
Low Ambient Temperature Operation Air Source Heat Pump for Hotel , Including evaporator, compressor, condenser, electronic expansion valve and economizer. The two ends of the housing of the economizer are respectively connected with the condenser and the electronic expansion valve, and the two ends of the heat exchange coil in the economizer are respectively connected with the evaporator and the compressor, so that the low-temperature and low-pressure gas in the evaporator is evaporated The refrigerant exchanges heat with the high-temperature and high-pressure liquid refrigerant before throttling in the economizer and then enters the compressor to increase the superheat of the return air of the compressor. It can also increase the subcooling degree before the refrigerant throttling. In the case of high energy consumption, the higher energy efficiency utilizes the high-temperature and high-pressure liquid refrigerant before throttling and the low-temperature and low-pressure gaseous refrigerant before the return gas to exchange heat to achieve the purpose of increasing the return gas superheat. It overcomes the disadvantages of the prior art that the cost increase and the volume of the main machine are increased by enlarging the evaporator, and the cost of the evaporator is reduced under the effect of ensuring the superheat of the return air of the compressor, and the volume of the main machine is reduced.
Energy-saving low-temperature compensation air energy water heater, air energy water heater includes air energy heat pump, heat preservation water tank and solar battery pack; heat preservation water tank is respectively connected with air heat pump and solar battery pack; the heat preservation water tank is provided with a control switch outside, and the heat preservation water tank has a built-in spring The heating wire is connected to the control switch based on the wire; the solar battery pack includes a photovoltaic panel, a controller, and a power storage unit, and the photovoltaic panel, the controller, and the power storage unit are connected in sequence, and the power storage unit is connected to the control switch connection. The utility model uses the solar battery pack to provide power for the heating wire. When the temperature of the hot water in the heat preservation water tank is lower than a certain temperature, the heating wire starts to work and generates heat to provide low temperature compensation for the hot water in the heat preservation water tank; and an electric heating wire is added The contact area with the water in the heat preservation water tank increases the contact area between the heating wire and the water; it ensures stable hot water use and saves electricity consumed during low temperature compensation.
