Waste heating recovery system
An apparatus is described for recovering waste heat from a refrigeration system having a compressor, condensor and evaporator coupled together for circulating a refrigerant comprising: heat exchanger means adapted to be connected to the system between the compressor and condensor and having an inlet for receiving the refrigerant from the compressor and an outlet for supplying the refrigerant to the condensor and a water line passing therethrough to which heat is transferred from the refrigerant. The water line is adapted to be connected at one end to a source of cold water; a holding tank connected to the other end of the water line for receiving at an inlet water to which heat has been transferred and storing the water and having an outlet; means connected to the holding tank outlet and adapted to greater than the capacity of the holding tank by means of one way valve means so that heated water flows from the holding tank to the storage tank when the pressure in the storage tank drops below the pressure in the holding tank upon removal of water from the storage tank; pump means connected between the holding tank outlet and connected to the heat exchanger means inlet by the water line for circulating heated water from the holding tank; means for sensing the temperature of the refrigerant prior to passage through the heat exchanger; means for sensing the temperature of the heated water prior to passage through the pump means; solenoid valve means connected between the water line and the source of cold water; and a central control unit means causes the pump means to circulate water when either the temperature sensed by the refrigerant temperature sensing means is above a predetermined value, or the temperature sensed by the water temperature sensing means is below a predetermined value, and for opening the solenoid valve means when the pump means is not operating to circulate water.
