An air source heat pump water heater comprises a solar energy collector, a heat pump circulating pump, a water supply pump, a water feeding electromagnetic valve, a solar energy circulating pump, a water tank temperature sensor, a panel and a heat pump controller. The air source heat pump water heater is characterized by also comprising a collector temperature sensor; the collector temperature sensor and the water tank temperature sensor are connected with the heat pump controller and temperature signals are input into the heat pump controller; the heat pump circulating pump, the water supply pump, a water return electromagnetic valve and the water feeding electromagnetic valve which are connected with the heat pump controller are controlled by the heat pump controller to switch on and switch off; the heat pump controller intelligently judges whether to start the solar energy collector or a heat pump to heat water according to the temperature difference of the solar energy collector and a water tank. According to the technical scheme of the air source heat pump water heater, solar energy and the heat pump water heater can be simultaneously controlled based on the original heat pump controller without an additional controller and accordingly the installation is simple and convenient and the cost is saved.
Description
technical field [0001] The present invention relates to a water heater, and more specifically, the patent of the invention relates to a novel air source heat pump water heater capable of simultaneously controlling solar energy. Background technique [0002] The air source heat pump water heater is a new type of hot water and heating product. It is a heating equipment and hot water device that can replace a boiler. Received. However, compared with the solar water heating system, the energy-saving effect of the air source heat pump water heater is worse, but the solar water heating system is far inferior to the air source heat pump water heater in terms of convenient use around the clock. As the world's industrialization progresses faster and faster, energy consumption is getting higher and higher, resources are getting scarcer, and pollution is getting worse. A hot water system combining an air source heat pump water heater and a solar water heating system was born. [000...
