Abstract
A system for cooling of water on a two wheeler using engine exhaust heat, said system comprising: input means adapted to receive exhaust gas from said engine; adsorber adapted to receive exhaust gas from said input means, said receiving being controlled by a first valve, said adsorber being a shell and tube heat exchanger such that said exhaust gas passes through said tubes and refrigerant adapted to be compressed in said shell of said heat exchanger, wherein, adsorbing material of said adsorber is heated upon receipt of said exhaust gas thereby making refrigerant to come out of said adsorbing material; air cooled condenser coil(evaporator cum condenser coil) placed in series with said adsorber; the condenser coil is a double tube heat exchanger coil which act as a condenser as well as an evaporator; the refrigerant is cooled and becomes liquid in the condenser coil: the said condenser cum evaporator coil is connected to the adsorber through a control valve; said control valve allows the flow of refrigerant to condenser coil in heating mode; the said control valve is opened after some time and allows flow of refrigerant back to adsorber; the said flow back of refrigerant to condenser coil produces refrigeration; during said refrigeration water is flown throw inner tube for cooling; the said water can be used as cold water for drinking purpose.
