Description
Technical Field
The invention belongs to the technical field of clean energy, and particularly relates to a solar energy, energy tower, water source heat pump and air source heat pump multi-mode heat supply and refrigeration system.
Background
At present, the building area of cities and towns in China reaches about 88 billion cubic meters, the total heating energy consumption is about 1.53 billion tons of standard coal/year, and the total energy consumption accounts for about 40 percent of the total energy consumption of the buildings in cities and towns in China, so that the reduction of the energy consumption in winter heating seasons is a feasible way for reducing the total energy consumption in China.
The air source heat pump is a device for transferring the heat energy of a low-level heat source to a high-level heat source, obtains low-grade heat energy from the air in the nature by taking the air as the heat source, applies work through electric power, converts the low-grade heat energy into usable high-grade heat energy and provides the usable high-grade heat energy for people, and has the characteristics of high efficiency, energy conservation and environmental protection. Compared with the traditional heating mode, the heating device has the advantages that the structure is simple, the use cost is only 1/4 of the electric heating mode, and compared with the traditional gas heating mode, the heating device does not consume any gas fuel, and the use cost is only 1/3 of the gas fuel. As a novel heating mode utilizing renewable energy, the solar heating mode collects heat energy in sunlight through temperature rise and phase change of working medium water in the solar heat collecting pipe, and the whole process does not consume fossil fuel and does not discharge harmful gas. The air source heat pump system and the solar heating system are used for replacing the traditional heating mode in China, so that the energy utilization rate can be improved, the energy consumption is reduced, and the problem of overlarge heating energy consumption in winter in China is effectively solved. However, the air source heat pump system and the solar heat collecting heating system have their limitations while having the above advantages. The solar heat collection and heating system is greatly influenced by weather factors, can only collect heat in the daytime, has limited heating time and poor stability, and cannot be used in continuous rainy days; the air source heat pump can frost on the outdoor finned tube heat exchanger when the air source heat pump is used for heating in cold northern areas and high-humidity cold southern winter. The frost layer can increase the heat conduction and heat resistance between the wet air and the surfaces of the fins, increase the resistance of the air flowing through the finned tube evaporator and reduce the air flow; along with the thickening of the frost layer, the heating performance of the heat pump system is gradually reduced, and the heat pump system cannot work in severe cases. The frosting problem is a main factor influencing normal heating of the heat pump unit in winter, and the popularization and application of the air source heat pump system are limited to a certain extent.
A novel heating system integrating the advantages of various systems is designed based on the characteristics of solar heat supply, energy tower heat supply, water source heat pump heat supply and air source heat pump heat supply, and the novel heating system is a development direction of the current heating energy-saving technology.
