Solar heating system, multi-heat-source heating system and multi-heat-source heat supply method

Abstract

The invention discloses a multi-heat-source heating system utilizing solar energy. The multi-heat-source heating system comprises an air source heat pump, a radiator, a radiator water inlet pipe and a radiator water return pipe, and further comprises a solar heat collector, a high expansion non-pressure water tank, a heat exchange high-pressure water tank and a solar heat collector electric supplement system. A heat collector water outlet pipe and a heat collector water return pipe are arranged between the solar heat collector and the high expansion non-pressure water tank. An expansion water tank water return pipe and an expansion water tank water inlet pipe are arranged between the high expansion non-pressure water tank and the heat exchange high-pressure water tank. An air source heat pump water inlet pipe and an air source heat pump water return pipe are arranged between the air source heat pump and the heat exchange high-pressure water tank. The radiator water inlet pipe and the radiator water return pipe are both connected with the heat exchange high-pressure water tank. The solar heat collector electric supplement system is arranged on the radiator water inlet pipe. A new idea is provided for rural-urban continuums without urban heat supply pipeline networks and natural gas pipeline networks and engineering construction temporary heating, and references are provided for new energy development, environment protection and sustainable development paths of China.

Description

technical field [0001] The invention belongs to the technical field of building heating engineering, and in particular relates to the design of a system engineering for comprehensive utilization of solar energy in building heating, and also relates to an automatic control method for comprehensive utilization of solar energy in building heating engineering. Background technique [0002] Temporary facilities for construction buildings generally cannot be connected to the urban heating pipe network, and only electric heaters and air conditioners can be used for heating. One has a low safety factor and the other has a high cost. Under the background of increasing operating costs of modern enterprises and fierce market competition, it will undoubtedly increase the burden on enterprises; in addition, with the rapid development of cities today, it is already a trend for enterprises to go out of cities and enter parks, but many urban-rural fringes are still affected by funds. The co...

Problems solved by technology

However, a single solar energy as a heat source is obviously not enough for an office building with an area of ​​more than 1,500 square meters in the northwest region. Therefore, a multi-heat source heating plan must be proposed. However, what heat sources are included in the multi-heat sources and how to choose heat sources are all under construction. Difficulties encountered in planning; in addition, there is no precedent for the multi-heat source heating system under the background of the current dominant urban central heating. Each heat source must have advantages and disadvantages. How to effectively combine the advantages of each heat source The reduction of construction input cost and use cost also increases the difficulty of initial construction design
