摘要:
Countercurrent flow absorber and desorber devices are provided for use in absorption cycle refrigeration systems and thermal boosting systems. The devices have increased residence time and surface area resulting in improved heat and mass transfer characteristics. The apparatuses may be incorporated into open cycle thermal boosting systems in which steam serves both as the refrigerant vapor which is supplied to the absorber section and as the supply of heat to drive the desorber section of the system.
摘要:
Sensible waste heat from industrial or other sources is boosted to useful temperature levels by combining at least one Rankine vapor generation cycle with at least one solution heat pump cycle. Waste heat is first utilized to boil off refrigerant in the Rankine cycle evaporator to provide a source of relatively high pressure vapor to an absorber in the solution heat pump. In the absorber, the vapor is contacted with a working solution of absorbent and refrigerant. As the refrigerant vapor is absorbed into solution, its latent heats of condensation and solution are given off at a temperature higher than the temperature of to a process (boosted output) stream the waste heat source. The working solution is then throttled to a relatively low pressure desorber where a portion of the refrigerant is desorbed as vapor from the solution by the further use of waste heat. The desorbed refrigerant vapor is then condensed and pumped to the evaporator for reuse. Working solution is recycled from the desorber to the absorber for reuse. Utilization of the sensible waste heat, first source is maximized by extracting successive portions of heat for use in the Rankine cycle evaporator section and then in a heat pump cycle desorber section. Multiple cycle systems are disclosed which boost the temperature of a portion of the waste heat to even higher levels than possible from the single cycle system.

A system is provided which improves the ability of cogeneration facilities to meet varying electrical power and process steam demands. One or more thermal boosting systems each having a Rankine cycle evaporator coupled with a solution heat pump cycle is integrated with the turbines of the cogeneration facility to maintain full steam flow through the turbines and provide a portion of the process steam demands on the facility. Optionally, a bottoming turbine is added to the system to further improve its flexibility to meet varying demands.

A hybrid air-conditioning system having an absorption refrigeration subsystem for sensible heat loads and a cooperating liquid desiccant dehumidification subsystem for latent heat loads incorporates additional apparatus for effecting the efficient transfer of available heat between the subsystems to improve the total system Coefficient of Performance (C.O.P.) over a wide range of latent heat load to sensible heat load proportions. Available heat recovery and system internal load generation are utilized in high and low latent load ratio regions, and modulated heat transfer using an additional series absorption refrigeration cycle loop is optionally utilized in the mid-latent heat load ratio region.
摘要:
A system and apparatus for compressing gaseous fluids, especially refrigerant gas vapors operating in refrigeration cycles, combining reciprocating pistons in a rotating cylinder member which is mounted for rotation in a stationary frame and is driven by an external source of rotative power. The cylinder block rotates in an encircling port ring member which contains inlet, interstage, and outlet port sets with the number of port sets, numbering more or less than the number of cylinders, to provide a vernier effect in the timing of connections between the port sets and the cylinders.

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.

A residential-type hybrid air conditioning system having a conventional refrigeration subsystem which handles system sensible heat loads and a liquid desiccant dehumidification subsystem which handles system latent heat loads additionally incorporates an evaporative cooler which cooperates with and receives heat from the dehumidification subsystem to increase the performance efficiency of the total system.
摘要:
A double-effect absorption refrigeration system is provided with a novel, generally concentric and vertically-elongated high-pressure condenser chamber, low-pressure desorber, and low pressure condenser combination. Such combination further includes novel annular liquid collection cups located at the combination lower extremes to receive high-pressure liquid refrigerant, low pressure concentrated refrigerent solution, and low-pressure liquid refrigerent. Flow restrictor devices are incorporated in distribution lines connecting the collection cups to a system evaporator/absorber assembly to further enhance temperature, concentration, and pressure conditions imparted to the liquids flowed for absorption purposes.
摘要:
The heating and cooling of structures is accomplished by driving a compressor of an air conditioning system with an internal combustion engine. The engine also drives an electrical generator to provide electrical power to the various components of the heating and cooling subsystem such as fans, motors, pumps, and controls. A constantly variable transmission apparatus and a differential power transmission are cooperatively connected to the engine to provide substantially constant speed operation of the generator.
