Abstract

The invention discloses a cold and hot water supply device by compositely utilizing energy. The device comprises four parts, i.e. a heat pump sub hot water system, a water tank subsystem, a heat-utilization heat-transfer subsystem and a solar photovoltaic power generation subsystem. A water distributor in a water tank of the device can be effectively controlled to realize the partition distribution of hot water with different temperatures, the water with higher temperature is located in a hot water area, and the water with lower temperature is located in a freeze water area, so that the economy and stability of the hot water supply system can be guaranteed. Heat quantity generated in solar photovoltaic power generation can be effectively utilized to improve the water supply temperature of the condensation side of the heat pump circulation, and reduce heat transfer temperature difference; and meanwhile, the domestic hot water and the freeze water can be supplied at the same time, the circulating efficiency of a heat-pump water heater system can be improved and the heat quantity generated in the photovoltaic power generation can be effectively utilized by utilizing a plurality of energy resources including a solar energy, an air source, a ground source and the like.

Description

technical field

[0001] The invention discloses a cold and hot water supply device for compound utilization of energy. Background technique

[0002] Traditional fuel energy is decreasing day by day, and the harm to the environment is becoming more and more prominent. At the same time, there are still 2 billion people in the world who do not have normal energy supply. At this time, the whole world is turning its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain sustainable development. Among them, solar energy has become the focus of people's attention due to its unique advantages. Abundant solar energy is an important energy source, which is inexhaustible, non-polluting, cheap, and an important energy source that human beings can use freely. Solar water heater? It converts sunlight energy into heat energy, and heats water from low temperature to high temperature, so as to meet people's demand for hot water in...
