Giant energy heat collection plate, heating and refrigeration system adopting heat collection plate and control method

Abstract

The invention discloses a giant energy heat collection plate, a heating and refrigeration system adopting the heat collection plate and a control method. The giant energy heat collection plate is provided with a light transmitting layer, a heat collection layer and a device layer in sequence from top to bottom; the light transmitting layer is made of a polycarbonate material or a high transmittance glass material; the heat collection layer is of a honeycomb porous structure made of an iron material or an aluminium material; and the surface of the heat collection layer is coated with a high temperature resistant coating by adopting a sputtering technology. The light transmitting layer is made of the polycarbonate material, insolation easily penetrates through the light transmitting layer, escaping of far-infrared radiation converted from sun shining on the heat collection plate is blocked at high efficiency, the heat collection effect is enhanced, and a good thermal insulation effect isbetter. The heat collection layer is made of iron or aluminium, the insolation is easily absorbed, heat is dissipated to air well, the insolation energy is converted at higher efficiency, and the energy converting efficiency of the heat collection plate is improved.

Description

technical field [0001] The invention belongs to the field of heating and cooling, and in particular relates to a huge-energy heat collecting plate, a heating and cooling system and a control method using the heat collecting plate. Background technique [0002] The construction industry has always believed that economy, ecology, low energy consumption and renewable energy supply for buildings are irreconcilable or even contradictory goals, and at least a compromise is to be found between these goals. However, a small number of ultra-low energy passive house projects that have been built in China have proved that as long as the energy consumption of buildings is reduced to the greatest extent, then economy, ecology and renewable energy supply can be well coordinated with each other. Fundamentally improving energy efficiency is the key to improving energy efficiency. For the buildings in the cold winter and hot summer areas where we live, it means to achieve very good thermal ...

AI Technical Summary

Problems solved by technology

To achieve a healthy indoor air exchange rate, the use of direct fresh air will cause a lot of ventilation heat loss

The fresh air system with heat recovery also only brings the cold air outside the building into the room, and the heat load sacrificed is very large
