摘要:
An insulated reflector for a low-intensity radiant energy heating system. Several embodiments are disclosed. In one embodiment, the reflector forms a chamber which is used to preheat fresh air admitted to the heated area.
摘要:
A relatively low temperature, low-intensity infrared heating system in which at least a substantial portion of the effluent in the emitter tube is recirculated and mixed with the hot effluent from the burner of burners to produce a uniform system temperature. A relatively long low-temperature exhaust leg is utilized to increase thermal efficiency. The burner or burners receive combustion air from outside the enclosure and valves are used to prevent reverse flow.
摘要:
An energy efficient system for controlling the environment in a greenhouse. The system includes an infrared heater, having a burner, a heat disbursement means and an exhaust means, and a layer of reflective and insulative material selectively deployable below the roof and inside the walls of the greenhouse to retain heat within the greenhouse, to prevent excess heat from the sun from entering the greenhouse and to reflect light into the greenhouse from the sun. The system also includes an air-to-water heat exchanger, connected at the exhaust end of the heater, that transfers heat from the heater's exhaust to water used in the greenhouse. The heated water is stored in an underground tank. A series of connected pipes, in communication with the tank, are set into the floor of the greenhouse to circulate the water through the floor to remove excess heat from the water.
摘要:
A gas or a fired radiant energy heating system wherein a burner is connected to a long radiator tube. Means are provided for balancing the heat output over the length of the tube thereby lowering the temperature at the burner end. In one embodiment, this entails use of a length of insulator in the tube adjacent the burner and a length of turbulator near the exhaust.
