Abstract

The invention provides a cold storage type instant heating hot pump water heater. The cold storage type instant heating hot pump water heater comprises a cold water tank, a main evaporator, a compressor and a hot water heat exchanger. According to the cold storage type instant heating hot pump water heater, the heat of a working medium in the cold water tank is absorbed through the main evaporator, bathing water is quickly heated in a heat exchange mode through the hot water exchanger, and energy loss in the hot water storage process of an existing heat pump water heater is avoided while instant heating is achieved; besides, the temperature of the working medium in the cold water tank is made to be lower than or equal to the environment temperature through absorption of the heat of the working medium in the cold water tank through the main evaporator, heat can be absorbed from the environment, and the energy utilization rate is further improved; and furthermore, as the temperature of the working medium in the cold water tank is free of the frosting phenomenon caused by the influence of the outdoor environment, the cold storage type instant heating hot pump water heater is suitablefor different seasons.

Description

technical field [0001] The invention relates to the technical field of heat pump water heaters, in particular to a cold storage instant 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 types, heat storage electric water heaters (including hot water tanks) and instant electric water heaters. Through the heating device, heat is generated under the condition of electricity to heat water, and at the same time, the temperature sensor is used to control the start and stop of heating. Thereby realizing the regulation to water temperature. Electric water heaters are low in cost, simple to install and easy t...
