Solar cooling

The parabolic trough makes possible the implementation of a 2-stage absorption chiller for the production of solar cooling. By this means, cooling processes and air-conditioning processes can be supported or even completly operated using renewable energy.

The thermal energy collected with the aid of parabolic trough collectors can be used as the driving energy for refrigeration. Physically, there are a variety of options for converting heat into cold.

The methods for refrigeration are dependent on the operating temperature of the generator. The use of parabolic troughs is particularly suitable in operation with a two-stage absorption chiller.

How it works:

The thermal energy from the parabolic trough reaches the cooling unit. If little or no cooling is required, the energy can be stored in an accumulator. The thermal energy in the refrigeration unit is used for the thermal compression of a refrigerant.

A cooling process is thereby set in motion without the use of expensive electrical energy. Depending on the configuration of the system, temperatures can be reached well below 0 °C. Due to rising energy costs and the growing interest in renewable energy, such systems are increasingly being employed.
