Composite type hot water system combining solar energy with heat pump water heater

Abstract

The invention provides a composite type hot water system combining solar energy with a heat pump water heater. The composite type hot water system comprises a solar energy system, a heat pump system and a temperature control system, wherein the temperature control system is used for connecting the solar energy system with the heat pump system, and comprises at least one temperature control valve and a temperature control panel, and the temperature control panel is used for controlling the opening and the closing of the temperature control valves. The composite type hot water system combining the solar energy with the heat pump water heater has the beneficial effects that through the arrangement of the temperature control system, the solar energy water heater and the heat pump water heater are skillfully combined, so automatic water supplementing is realized, first usage of the solar energy hot water is realized, and cost is reduced.

Description

technical field [0001] The invention relates to a hot water system, in particular to a composite hot water system combining solar energy and a heat pump water heater. Background technique [0002] At present, water heater products mainly include gas water heaters, electric water heaters, solar water heaters and heat pump water heaters. They have both their own advantages and disadvantages: gas water heaters are the most convenient to use, ready to use, but poor safety performance, improper installation and use can cause carbon monoxide poisoning, there is a danger of explosion and fire, and serious pollution, so they are not widely used in the market. , causing some consumers to dare not pay attention to it, and the sale of it has been banned in Hong Kong; the initial investment of electric water heaters is not large, and the safety of use is acceptable, but the cost of use is high and the power consumption is too large. [0003] At present, there are two types of energy-sa...

They have both their own advantages and disadvantages: gas water heaters are the most convenient to use, ready to use, but poor safety performance, improper installation and use can cause carbon monoxide poisoning, there is a danger of explosion and fire, and serious pollution, so they are not widely used in the market. , causing some consumers to dare not pay attention to it, and the sale of it has been banned in Hong Kong; electric water heaters, the initial investment is not large, and the safety of use is acceptable, but the cost of use is high and the power consumption is too large

However, although solar water heaters have low cost of use and are advocated by the government, they have high initial investment costs, are greatly affected by the climate, have a single heat source, poor reliability, and cannot be used around the clock, which causes a lot of inconvenience to users; Although the water heater manufactured by the heat pump principle can generally reach more than 300% annual heating efficiency, it cannot directly use the precious solar energy, and the cost of use is still relatively high.
