Introduction Solar heating and cooling

technology receive the thermal energy from sun and utilize this energy to provide space heating and cooling for residential, commercial and industrial applications.

The main function of solar system is to convert sun light into heat.

The primary requirement of Solar Heating and Cooling System is to setup the light collectors with higher efficiency.

Why we need Solar Heating and Cooling System?

Eliminating the need for electricity or natural gas.

An economical alternative to solar photovoltaic (SPV) system.

Solar heating and cooling systems simply eliminate the need for electricity to cool or heat the air and water in a home or business.

PASSIVE HEATING

Passive solar heating is the least costly technique to heat home space. The main aim of this system is to kept out heat in summer and kept in heat in winter from sun light. Passive solar heating also depends on ventilation or windows provided in buildings or houses.

Active Heating» This system can be used as commercial

hot water as well as space heat. » A space heat application involves some

additional connecting hardware for space heat distribution system.

» The two basic types of active solar space-heating systems use either liquid or air as the heat-transfer medium in their solar energy collectors

» Liquid-based systems heat water and air-based systems heat air in the collector.

Components Collectors to absorb energy Pumps or Blower Storage tank Backup heating system (Auxiliary

heating system) Heat Exchanger

Process of active space heating

» Liquid/air gets heated up in the flat plate collector.

» The hot fluid pass to storage tank.

» Fluid from storage tank Pump /blower Heat exchanger.

» The heat exchanger blow out hot air and heated up the surrounding living space in the building.

» Again the cool air /water passes to storage tank ,which supplied to flat plate collector for heating.

» Absence of the solar energy auxiliary heater used for space heating.

» The two basic types of active solar space-heating systems use either liquid or air as the heat-transfer medium in their solar energy collectors

» Liquid-based systems heat water and air-based systems heat air in the collector.

» Both of these systems collect and absorb solar radiation, then transfer the solar heat directly to the interior space or to a storage system, from which the heat is distributed.

Advantages of Solar Heating and Cooling over Conventional MethodsSHC reduced the conventional

heating and cooling cost up to 35-40%.

This system helps by providing employment to establish SHC system.

Direct reduction can be made by using SHC system.

Combination of heating and cooling easily available for all type of back up heat source.

Energy sourced easily available in maximum quantity.

Collectors are used can be recyclable.

Conclusion :-Solar heating and cooling system

reduce the operating cost as compare to conventional methods.

Efficiency of conventional method of heating and cooling can be increased 35-40%with the help of solar heating and cooling system.

The main consideration will be to reduce the initial cost of the system in future.

This system provide healthy environment to the employee in industries by heating and cooling mechanism.
