Abstract

The invention provides a solar energy instantaneous-hot heat pump water heater. The heat pump water heater comprises a solar energy heat collector, a heat pump circulating pipeline with a circulatingpath switching device, and a hot water heat exchanger; the solar energy heat collector is in series connection with a pipeline between a heating expansion valve and a heat storage expansion valve in the heat pump circulating pipeline; and a condenser of a heat pump circulating system is arranged in the hot water heat exchanger. The circulating path of the heat pump circulating pipeline is switchedthrough the circulating path switching device, during bath, the heat pump circulating pipeline is switched to a heating circulating path, the heat pump circulating pipeline is utilized to quickly heat water of the hot water heat exchanger, and thus the instantaneous-hot effect is achieved; and when not bath, the heat pump circulating pipeline is switched to a heat storage circulating path, the solar energy heat collector and the heat pump circulating pipeline are utilized to heat a working medium in a cold water tank, the heat collecting temperature of the solar energy heat collector is decreased, solar energy is effectively utilized, the operation rate of the solar energy heat collector is further decreased, and the technical defect of the low heating speed is avoided.

Description

technical field [0001] The invention relates to the technical field of heat pump water heaters, in particular to a solar energy instant heat heat pump water heater. Background technique [0002] In people's daily life, domestic hot water accounts for a large proportion of daily water use, and hot water heating devices are gradually becoming popular. There are four types of water heaters commonly used at present, namely electric water heaters, solar water heaters, gas water heaters and heat pump water heaters. Among them, electric water heaters are divided into two categories, heat storage electric water heaters (including hot water tanks) and instant electric water heaters. The electric water heater generates heat to heat the water through the heating device under the condition of electricity, and at the same time controls the start and stop of the heating through the temperature sensor, so as to realize the regulation of the water temperature. Electric water heaters are l...
