Evaporator assembly, water heater and control method of water heater

Abstract

The invention provides an evaporator assembly, a water heater and a control method of the water heater. The evaporator assembly comprises a photovoltaic / photothermal cell and an evaporator. The photovoltaic / photothermal cell generates power through solar energy. The evaporator is in contact with the photovoltaic / photothermal cell and is used for absorbing heat generated in the power generation process of the photovoltaic / photothermal cell and heat in air. According to the evaporator assembly provided in the scheme, solar energy and heat energy in the air can be absorbed, the photovoltaic / photothermal cell can be utilized for generating power through solar energy, and therefore power generated by the photovoltaic / photothermal cell can be utilized for being supplied to a compressor, fans, a throttle valve and other loading equipment of the water heater for use; and drive of the water heater can be achieved through solar energy, and then energy in the nature can be utilized reasonably and effectively so as to reduce energy consumption of products. In addition, the evaporator of the structure provides a mounting platform for the photovoltaic / photothermal cell, and therefore a structure for mounting of the photovoltaic / photothermal cell does not need to be additionally arranged, the structure of the products can be simplified, and the machining cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an evaporator assembly, a water heater and a control method for the water heater. Background technique [0002] At present, both heat pump water heaters and traditional solar water heaters have the advantage of saving energy. As an abundant and clean energy, solar energy can not only utilize heat energy, but also generate electricity. The PV / T module, as a photovoltaic / photothermal comprehensive utilization module, can be used for both hot water and DC power generation. However, the power generated by the PV / T module needs to be stored in batteries and converted into AC power through inverters. In order to meet household needs, traditional heat pump water heaters can only use electric energy, not solar energy, which will cause a large consumption of electric energy, and thus do not conform to the concept of energy saving and environmental protection. [0003] Therefore, ho...
