Description

technical field [0001] The invention belongs to the application field of heating, ventilating and air-conditioning technology, and relates to indoor thermal comfort adjustment and system energy-saving process, in particular to an all-weather solar energy supply system. Background technique [0002] Energy shortage and environmental pollution are the primary problems facing human beings in the 21st century. It is considered that the only way out for future social development is to vigorously develop energy-saving and emission-reduction technologies in various fields and to seek clean and renewable energy to replace the increasingly depleted traditional fossil energy. It is one of the technical directions of key development in the medium and long-term scientific and technological development planning outline. This includes two meanings, one is to develop energy-saving technologies and systems for traditional energy sources, and the other is to search for new energy sources and...

[0005] The Chinese patent application number 201010509782.3 discloses a capillary network heat pump system using solar energy, which is suitable for central air-conditioning systems. This system uses the heat pump system to increase the temperature of water (28-32°C) and transport it to the capillary network when the climate is harsh in winter. system, the system is easily affected by the climate, and the efficiency of the heat pump unit will be affected in areas with lower ambient temperatures in the north

The Chinese patent with application number 201010611919.6 discloses a composite hot water heating and cooling device with solar energy, heat pump and capillary network. The device uses a hot water storage tank to store solar energy. Temperature, this kind of device is sensible heat storage for solar energy storage, and the volume of the hot water storage tank is large, which will lead to a huge system and is not suitable for effective promotion

The Chinese patent with application number 201110190676.8 discloses an indoor geothermal heating structure using capillary network and phase-change thermal storage material. The structure lays phase-change thermal storage material and capillary network equipment under the floor of users. The potential hazards caused by laying heat storage materials under the user's floor are the damage to the user's floor caused by the thermal expansion and contraction of the heat storage material and the inconvenience of maintenance.

In the Chinese patent application number 201120081136.1, the Chinese patent patent application number 201110160980.8, and the Chinese patent application number 201010509781.9, the heating method of ground source heat pump or water source heat pump system combined with solar energy and capillary network system is proposed. This structure Although the method also uses solar energy, the heat pump must still be turned on to supplement energy at night, and the system is more complicated

The Chinese patent with the application number 200920350744.0 discloses a new ground source heat pump capillary roof air conditioning system based on solution dehumidification. The system directly uses the ground source heat pump as the heat source and does not use solar energy as a clean energy source.
