A condensate trap for a furnace system includes a trap inlet configured to receive combusted gases, a condensate chamber coupled to the trap inlet and configured to trap condensate, a trap outlet coupled to the condensate chamber and configured to exhaust the combusted gases, a header box inlet configured to receive condensate from a header box, and a condensate outlet configured to drain condensate from the condensate chamber. Combusted gas that passes through the condensate trap provides heat to condensate within the condensate trap to thaw frozen condensate or to prevent condensate from freezing.

A water heater includes a burner generating combustion gas, a heat exchanger heating water which flows through the inside, through heat exchange with combustion gas generated in the burner, a fan supplying air to the burner, and a housing storing these components. The water heater has a water entry portion in a top plate of the housing. A water supply pipe for supplying water to the inside of the heat exchanger is connected to the water entry portion. The water entry portion is arranged to be included, in a plane view, in at least one component constituting the heat exchanger and an exhaust path for combustion gas which has passed through the heat exchanger. The component is made of a material having corrosion resistance against drainage water resulting from condensation of combustion gas.

In one aspect, a refrigeration system is provided. The refrigeration system includes a refrigeration circuit configured to condition an air supply, a subcooling circuit configured to cool the refrigeration circuit, the subcooling circuit including a subcooling condenser, a subcooling heat exchanger, and at least one adsorption bed, and a heat generation system thermally coupled to the subcooling circuit.

The present invention is a method of optimizing radiant and thermal efficiency of a gas fired radiant tube heater. A heat exchange blower receives intake air and delivers intake air through a heat exchanger as pre-heated air to a combustion air blower. The combustion air blower receives pre-heated intake air from the heat exchanger and then provides the pre-heated intake air to a burner for mixing with fuel. The fuel-intake air mixture is burned in the burner thereby producing combustion gasses which are fired into a radiant tube. The exhaust combustion gases pass through the balance of the radiant tube and through the heat exchanger where residual heat is transferred and extracted from the combustion gases to pre-heat the intake air. The turbulators are configured to increase the turbulence within the radiant tube and are placed within the initial 10′ to 30′ of the radiant tube after the burner to increase the tube temperature and the radiation emitted from this section of the radiant tube.
