Shower, heating and air conditioning complex system device for producing hot water by using solar energy, air source and low power

Abstract

The invention relates to a shower, heating and air conditioning complex system device for producing hot water by using solar energy, air source and low power. The device is formed by grafting and compounding a solar water heating system, a shower system, a floor heating system and an auxiliary heating system, and is provided with a control system; the auxiliary heating system is formed by grafting and compounding an air source pump and an air conditioner; in a steam compression refrigeration system of the air conditioner, a third heat exchanger which takes water as a heat exchange medium and one of a first heat exchanger and a second heat exchanger which takes air as the heat exchange medium in the system are connected with each other in parallel by using a pair of tee joints and two pairs of electromagnetic valves; and the third heat exchanger is provided with a temperature controller, is connected with a solar hot water storage tank by using a water inlet pipe and a water outlet pipe in a sealing way, and is connected with a hot water pump and an electromagnetic valve. The device has the advantages of saving electricity by 70 percent compared with an electric heater and saving a host compared with a special air-source heat pump, can be used for heating in winter and used for conditioning air in summer, recovers waste heat discharged from an original outdoor unit for producing hot water used for shower without reducing an energy efficiency ratio, acquires two gains by using one part of power, saves energy and reduces emission.

Description

technical field [0001] The present invention relates to the complementary and comprehensive utilization of solar heat utilization technology, air source heat pump and air conditioning technology, especially relates to the use of solar water heating system to produce hot water in sunny days, and the use of air source heat pump and low valley electricity to produce hot water in cloudy and rainy days and winter. Households or units shower all year round, heat in winter and air-condition in summer, use one electricity, get two incomes, form a cooling and heating cycle economy, save energy and reduce emissions, involving low-carbon technology. technical background [0002] Most households and units at home and abroad use fossil fuel boilers to provide hot water for year-round showers and winter heating. The disadvantages are that the reserves of fossil fuels are limited and will eventually be exhausted, and the second is the emission of CO 2 and other harmful gases, causing air p...

Problems solved by technology

[0002] Most households and units at home and abroad use fossil fuel boilers to provide hot water for year-round showers and winter heating. The disadvantages are that the reserves of fossil fuels are limited and will eventually be exhausted, and the second is the emission of CO 2 and other harmful gases, causing air pollution, global warming, and frequent natural disasters. Some families and units at home and abroad now install solar water heating systems to provide hot water showers and winter heating. The advantage is that solar energy does not pollute the environment and costs nothing. The disadvantage is that it needs to install another heating device for auxiliary heating in rainy days and winter for about half a year. Some use electric heaters or electric boilers for auxiliary heating. The disadvantage is that the heating coefficient is 1:0.95, and the consumption The electricity is relatively large, and some use a single-function air source heat pump water heater to supplement the solar water heating system and provide auxiliary heating on rainy days. The total investment of the hot water system and the air source heat pump has doubled. At present, most users cannot accept it, and it is difficult to promote it in the market. Therefore, people have an idea: whether it is possible to study a new type of auxiliary heating device, which must be like air The source heat pump is as efficient and energy-saving, and the cost is lower or close to that of electric water heaters or electric boilers, so as to replace electric heaters and electric boilers as an auxiliary heating device for solar water heating systems in rainy days and winter
