Hot and cold storage

Abstract

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.

1 . A thermodynamic cycle of refrigeration system for controlling heating and cooling in a room comprises:
 a) A circulating refrigerant passes through compressor ( 1 ) as vapor, the vapor is compressed and exist the compressor superheated the superheated vapor passes through the shell and tube type condenser ( 15 ) which first cools and removes the superheat by circulating water through tube of condenser and fan coil unit ( 2  &  5 ) with condenser water pump ( 16 ) the said vapor is condensed into liquid this liquid is passes through the evaporation coil ( 4 ) and is vaporized by the cooling of the warm air by a fan ( 6 ) across the evaporation coil   b) Once the temperature of hot room goes beyond the required temperature the thermostat ( 7 ) switch ON the exhaust fan ( 8 ) and the fresh air fan ( 9 ) to maintain temperature of hot room and once the atmospheric temperature is higher than hot room temperature then the thermostat ( 10 ) gets ON and switched OFF fresh air fan ( 9 ) and at the same time the water pump ( 11 ) gets starts and sprinkles water on both sides of the condenser coil the said water pump ( 11 ) decrease the temperature and increase the humidity of hot room   c) A heater ( 14 ) provided at the hot room to increase the temperature and decreases the humidity of hot room.   
     
     
         2 . A thermodynamic cycle of refrigeration system for controlling heating and cooling in a room temperature as claimed in claim- 1  wherein once the humidity of hot room goes down then the required water pump starts with the humidity stat ( 12 ). 
     
     
         3 . A thermodynamic cycle of refrigeration system for controlling heating and cooling in a room temperature as claimed in claim- 1  wherein the warm air in hot room passes through the coil and gets heated up with fan ( 5 ), the said heat is absorbed by the product kept in hot room. 
     
     
         4 . A thermodynamic cycle of refrigeration system for controlling heating and cooling in a room temperature as claimed in claim- 1  wherein water pump ( 11 ) get starts and sprinkles water on both sides of the condenser coil when atmospheric temperature is higher than hot room temperature. 
     
     
         5 . A thermodynamic cycle of refrigeration system for controlling heating and cooling in a room temperature as claimed in claim- 1  wherein a heater ( 14 ) is provided in the hot room for initial heating the fresh product if necessary, and to reduced the humidity with the help of humidity stat ( 12 ). 
     
     
         6 . A method for controlling heating and cooling in a room temperature comprises the steps of circulating refrigerant enters the compressor ( 1 ) as vapor, the said 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 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.
