Solar Refrigeration and Air conditioning system

Solar Refrigeration and Air conditioning system

Solar air conditioning refers to an air conditioning (cooling) system that uses solar power, power from the heat obtained from Sun’s rays.

The technologies that are being developed for gas cooling systems are the same ones being developed for active solar space cooling systems. Desiccant cooling systems and advanced absorption systems are the primary technologies that are used.

1. Desiccant system

A moisture absorbing material (desiccant) is located in the air stream going into the living space. As the air passes through the desiccant, which is usually located on a wheel that slowly rotates into the air stream, moisture is removed from the air, dropping the humidity level in the air stream to the point that an evaporative cooler can then cool the air. The desiccant is dried by the heat generated by the solar collectors as it rotates out of the air stream.

2. Absorption system

Heat from solar collectors separates a low boiling refrigerant in a generator which receives the pressurized refrigerant from an absorber. Solar heat can also be used in the evaporation stage of the cycle.

  1. This is the perfect blog for anyone who wants to know about this topic. Air conditioning service is a very popular form of cooling. The system is based on distributing the air from a centralized hub that is a high-power cooling unit. This unit provides the refrigeration. The content of your site is very informative. Thanks...
