A burner apparatus for combustion of gaseous fuel and air, for use in range-top type environments, is provided. The burner apparatus includes a burner housing, an inlet, a combustion chamber, and a heat absorbing and radiating quarl surrounding the outlet to the combustion chamber. The burner apparatus is advantageously configured so as to provide for substantially uniform heating of an object supported above the combustion chamber, through a combination of convective and radiative heat transfer.

Burner apparatus

A absorption refrigeration system having cooling and heating modes of operation functions with a double-effect or 'split' refrigeration cycle having approximately the same refrigerant concentration span in each cycle loop. The system includes a novel direct expansion combined evaporator and absorber assembly with improved heat transfer characteristics and with interchangeable liquid flows accomplished through actuation of a conventional reversing valve. Also, the system is provided with improved recuperative heat exchangers to further increase system energy conversion efficiencies.

Double effect air conditioning system

Systems and methods are provided to regulate the environment in a greenhouse where food and flower production is carried out, and in which outside air is inducted into the enclosure of the greenhouse through an evaporative cooler. A portion of the inducted air is recirculated, selectively heated or cooled and dehumidified, and mixed with the inducted air after contact with the agriculture in the greenhouse.

Method and system for controlling the environment in a greenhouse

A method, apparatus and system is provided for controlling the rate of insolation transmission through the roof of a building, such as a greenhouse. The roof is provided with translucent panels through which liquid containing opaquing material passes. Control is effected by varying the amount of opaquing material passing through the panels, according to preselected optimum fulfillment of the combined heating, cooling and insolation needs of the building under varying atmospheric conditions.
