solar refrigeration

Principle: there are mainly absorption type, adsorption type, cold tube type, dehumidification type,jet type and photovoltaic refrigeration types

1.solar energy absorption type refrigeration

Solar collector is used to collect solar energy to drive theabsorption refrigeration system, and the phase change latent heat of liquid cooling agent is used to store energy, and its gasification at low pressure and low temperature. So far, the most used solar air conditioning method has been demonstrated. Most are lithium bromide-water system, and some use ammonia-water system.

2,.solar energy adsorption type refrigeration

Type refrigeration, the combination of an evaporative refrigeration, with solar energy as heat source, using the working medium for usually active carbon, methanol, molecular sieve, water, silicone, water and calcium chloride, ammonia, etc., using solar collector adsorption bed after heating for stripping refrigerant, by heating desattach —— condensation —— adsorption —— evaporation in several links such as refrigeration.

3.solar energy dehumidification air conditioning system

It is a open cycle adsorption refrigeration system. The basic characteristics are desiccant dehumidification and evaporative cooling, which is also an air conditioning system suitable for the use of solar energy.

4. Solar energy jet type refrigeration

Through the heating of solar collector, the low boiling point working medium is changed into high pressure steam. When passing through the nozzle, due to the high outflow speed and low pressure, the low pressure steam generated by the evaporator around the suction chamber into the mixing chamber, and the refrigerant is vaporized in the evaporator to achieve the refrigeration effect.

5.solar energy cold control cold

This is a kind of intermittent refrigeration, the main structure is composed of solar cooling tube, collector box, refrigeration box, accumulator and cooling water circuit, etc., is a special adsorption refrigeration system.

6. Solar semiconductor refrigeration

The system consists of four parts: solar photovoltaic converter (solar cell), CNC mismatch device, energy storage equipment (battery) and semiconductor refrigeration device. The solar photovoltaic converter outputs direct current, one part is directly supplied to the semiconductor refrigeration device for refrigeration operation, and the other part is stored in the energy storage equipment for cloudy days or night use, to ensure that the system can operate normally all day long.
