摘要： The abstract concerns an expeller with six pump tubes positioned round the circumference of a circle. A weak refrigerant solution is conveyed through the tube by rising vapor bubbles. Heating is by means of sich flame tubes. To improve heat transfer, the pump tubes are welded to the flame tube. The pump tubes lead into an exhaust-gas flue and are located inside this flue. The hot exhaust gases can therefore transfer heat to the weak refrigerant solution.

摘要： An air cooling unit for a vehicle having a source of energy, such as heat from crankcase oil or transmission oil or a source of electrical power, such as an alternator. The cooling unit is of the absorption type and includes a condenser in series with an evaporator, an absorber and a boiler. The cooling unit is provided with a refrigerant, such as ammonia, and an absorption fluid, such as water. Hydrogen gas can optionally be placed in the cooling unit to move between the evaporator and the absorber to reduce the partial pressure of the refrigerant. A return line in the form of a coil extends from the boiler to an inlet of the absorber to return the absorption fluid to the absorber after the absorption fluid has been separated by heat from the refrigerant gas in the boiler. All of the components of the cooling unit are sized, shaped and located so that the cooling unit provides a compact package capable of being fitted into a relatively small space. A fan can be provided to blow air past the evaporator and through the vehicle for cooling the interior thereof. In one form of the cooling unit, the boiler is provided with heated oil to serve as a heat source, the oil being taken either from the crankcase of the vehicle or from the transmission of the vehicle. In another form of the invention, the boiler includes an electrical resistance heating element in a housing for receiving a mixture of refrigerant and absorption fluid from the absorber, the electrical resistance heating element having means for coupling the same to an electrical energy source, such as the alternator of the vehicle.

摘要： A single-pipe boiler construction in an absorption refrigerating apparatus which operates with inert gas, an absorption solution that is rich in refrigerant. The latter is lifted in a central pump pipe in which vapor is expelled and the weak solution thus formed flows downwardly in an outer pipe. At least one heat source is arranged in heat-conductive contact with the outside of the outer pipe and heat from the heat source is conducted through the weak solution in the outer pipe to the pump pipe and its contents. Heat is supplied directly by conduction to the outer pipe and a direct heat-conductive connection is arranged between the outer pipe and the pump pipe.

摘要： A spray generator for an absorption refrigeration system that includes a heat exchanger comprised of a multiplicity of variably spaced heat exchange tubes. The tubes are spaced close together near the top of the heat exchanger and spaced more widely apart near the bottom of the heat exchanger. Dilute absorbent solution is sprayed down through the heat exchanger. The close nesting of the tubes in the top portion of the heat exchanger retards liquid flow and aids heating of the solution. The wide spacing of the tubes in the lower section of the heat exchanger facilitate vapor flow out of the heat exchanger and eliminates liquid "blow-off". The top tubes are covered by a baffle to prevent the liquid solution from splashing out of the heat exchanger off of these top tubes.

摘要： An improvement in refrigerators of the absorber type in which heat from a flame circulates the refrigerant in the refrigerating cycle, particularly for use in caravans. To prevent the flame being extinguished in draughty conditions there is provided shielding means for protecting the flame, a flue extending from above the flame upwardly to an exit into ambient air, and means at the flue exit such as a venturi device adapted to provide a reduction of pressure from ambient air to the interior of the flue in draughty conditions of the ambient air. Preferably, the shielding means totally encloses the flame and is provided with an inlet connection pipe adapted to provide access for ambient air to the interior of the shielding means, the entrance to the inlet connection pipe having baffles and foils adapted to prevent any reduction of pressure from ambient air to the inlet connection pipe interior in draughty conditions of the ambient air. An ante chamber is preferably interposed in the inlet connection pipe and a moisture trap is preferably interposed in the flue.
