Abstract:
A thermal treatment system for supplying thermally conditioned or purified water for human or animal consumption, industrial processes, environmental containment, or removal of foreign species. The water purifier includes a heat exchanger for exchanging heat between outgoing thermally conditioned or purified water and incoming makeup water; a water heater is connected to the heat exchanger so as to receive pre-heated incoming makeup water, where the water heater subsequently heats the incoming preheated makeup water to a set-point temperature in the case of thermally conditioned water and for purified water also holds the water for a period of time sufficient to inactivate selected organisms to a predetermined level. The heat exchanger has one or more treated water outlets for supplying thermally conditioned or purified water at slected temperatures.

Abstract:
Disclosed in the present invention are a gas discharge device for discharging non-condensable gas in a refrigeration and air conditioning system, and a method thereof. The gas discharge device comprises a cold accumulation tank, and a condensation tank accommodating the cold accumulation tank. The cold accumulation tank stores a quantity of cold by means of a cold accumulation material. The condensation tank is used for separating a gas mixture of gaseous refrigerant and non-condensable gas exiting the system into liquid refrigerant and non-condensable gas, by causing the gas mixture of gaseous refrigerant and non-condensable gas to undergo heat exchange with the cold accumulation material in the cold accumulation tank; the isolated liquid refrigerant is led into the system, and the isolated non-condensable gas is discharged from the condensation tank. The method comprises a cold accumulation process, a condensation process, a gas discharge process and a liquid discharge process.
