Embodiment Construction

[0020] In view of the disadvantages of the current evaporator frosting and defrosting, this paper proposes another technical route for the general technical requirements for the evaporator to be placed outdoors, such as figure 1 The new type of heat pump water heater shown, the heat water heater consists of two systems, one is the air source heat pump water heater system; the other is the solar heat pump water heater system. 2. The expansion valve 3, as well as the water pipeline and connecting pipeline, are all inherent configurations of the heat pump water heater.

[0021] Different from the general configuration, the indoor part includes water tank 2 and compressor 1. These two components belong to the solar heat pump hot water system and the air source heat pump water heater system at the same time. The existence of the common part of the dual system can effectively save costs. As a heat pump water heater The inherent configuration of the heat pump water heater should also...

Abstract

The invention discloses a heat-pump water heater which comprises an indoor portion and an outdoor portion. The indoor portion comprises a water tank with a heat exchanging device and an evaporator connected with the heat exchanging device through a compressor. The outdoor portion is provided with an outdoor evaporator connected with the evaporator in parallel, one node of parallel connection is connected with a pipeline through a two-position three-way valve, and the outdoor portion comprises a temperature sensor for driving the two-position three-way valve to be switched. By means of the heat-pump water heater, a purpose of defrosting the evaporator is achieved.

Description

technical field [0001] The invention relates to a heat pump (Heat Pump) water heater. Background technique [0002] At present, there are mainly four types of water heaters: gas water heaters, electric water heaters, solar water heaters, and air source heat pump water heaters. Solar water heaters and air source heat pump water heaters are more and more popular with users for their energy saving and comfortable features, but there are inevitably differences between the two. Some disadvantages are that solar water heaters are seasonal due to environmental influences, and air source heat pump water heaters still need to be driven by electricity and consume electricity. The combination of solar energy and air source heat pump water heater can solve this problem well. It can not only make full use of solar energy to achieve energy saving, but also make up for the seasonal shortage of solar energy through air source heat pump. [0003] A heat pump water heater is a device that us...
