Solar water heater heat exchange water tank for passive house and solar water heater

Abstract

The invention relates to the technical field of passive house energy conservation, in particular to a solar water heater heat exchange water tank for a passive house and a solar water heater. A tank body is sequentially provided with a shell, a heat preservation layer and an inner shell from outside to inside, a hot water chamber is arranged in the tank body, the space outside the hot water chamber in the tank body is a pressure balance chamber, the pressure of the pressure balance chamber is less than that of the hot water chamber in the normal working state, and when the temperature of hot water reaches a set value and the hot water is consumed, the hot water chamber no longer supplements cold water, but fills compressed air into the pressure balance chamber. Compared with the prior art,the solar water heater heat exchange water tank has the following beneficial effects that, 1) the water tank conforms to the concept of environmental protection and energy conservation of the passivehouse, the water tank is divided into the hot water chamber and the pressure balance chamber, and the volume of the hot water chamber can be adjusted according to requirements; (2) the volume of thehot water chamber can be set according to the heat exchange efficiency of the solar energy and the use requirements of the hot water; and (3) systematic monitoring and real-time acquisition of pressure, temperature and flow parameters can be realized, the normal and stable operation of an energy system of the passive house can be guaranteed, and the maximization of energy utilization is realized.

Description

technical field [0001] The invention relates to the technical field of passive house energy saving, in particular to a passive house solar water heater heat exchange tank and a solar water heater. Background technique [0002] Passive house is a master of building energy saving concepts and various technical products. It makes full use of renewable energy such as solar energy and geothermal energy to make the primary energy consumption for heating not more than 15 kW / square meter. Such a low energy consumption standard is currently mainly achieved through high heat and sound insulation, strong airtight building exterior walls and renewable energy. my country's building energy consumption accounts for 1 / 3 of the total energy consumption, of which heating energy consumption per unit area accounts for 60% of the entire building energy consumption. Efficient use of renewable energy is an important way for the sustainable development of society. Passive houses are a low-energy bu...

Problems solved by technology

This patent attempts to solve the problem that when the hot water flows out, the water tank needs to be filled with cold water at any time, so that the water temperature in the water tank keeps dropping, and the temperature of the hot water becomes lower as the water is used, but it has not been able to adjust the solar energy according to the change of the heat gain. The water output of the water heater, and the large volume of the water tank itself also limits its application
