<p>A thermodynamic cycle of refrigeration system for controlling heating and cooling in a room / storage consisting -of compressor (1) circulating refrigerant which enters in the compressor (1 ) as vapor. The vapor is compressed and then exists the compressor superheated, the superheated vapor passes through the condenser (2) which first cools and removes the superheat. The vapor is condensed into a liquid by removing additional heat pressure and temperature by fan (5) across the condenser coil. The warm air in hot room passes through the condenser coil and gets heated up, this heat is absorbed by the products kept in hot room, the said liquid refrigerant goes through the expansion valve (3) when pressure suddenly drops down, flash evaporations takes place. The cold liquid vapor mixture then travels through the evaporation coil (4) and is vaporized by the cooling of the warm air by a fan (6) across the evaporation coil, the refrigerant vapor returns to the condenser inlet to repeat the cycle. Exhaust fan (8) and fresh air fan (9) helping to maintain temperature of hot room. Water pump (11) decrease the temperature and increase the humidity of hot room. Heater (14) increases the temperature if necessary and decreases the humidity of hot room.</p> |
