| An air conditioning system is disclosed which takes advantage of low ambient temperature conditions so as to activate a refrigerant flow that bypasses the compressor. The activation of the refrigerant flow is achieved by the intelligent control of a pump positioned between the outlet of the condenser and the inlet of an expansion device upstream of the evaporator. The refrigerant flow produced by the pump does not require any particular positioning of the condenser and evaporator components with respect to each other. The evaporator preferably absorbs heat from water circulating in a secondary loop which is used to remove heat from a building by one or more fan coil units. | ||||||

| An integrated environmental control system for providing conditioned air supply in an aircraft is provided. The system includes an integrated bootstrap air cycle subsystem and a regenerative air cycle subsystem, which are in heat exchange relationship. The bootstrap and the regenerative air cycle systems are also in heat exchange relationship with a liquid cooling cycle subsystem. In the bootstrap cycle, bleed air is compressed and expanded. After absorbing heat from the liquid cycle, the expanded air from the bootstrap cycle is received and expanded by a first turbine of the regenerative air cycle. Before it is received by a compressor of the regenerative cycle, the air flow, which is expanded and cooled by the first turbine, absorbs heat from the liquid cycle, supplies air to the cabin and absorbs heat from the bootstrap cycle. After the compression, the air flow is received by a second turbine of the regenerative cycle and expanded. The expanded air flow merges into the air flow from the first turbine of the regenerative cycle. | ||||||
| 210 | Electro-adsorption chiller: a miniaturized cooling cycle with applications from microelectronics to conventional air-conditioning | US09922712 | 2001-08-07 | US06434955B1 | 2002-08-20 | Kim Choon Ng; Jeffrey M. Gordon; Hui Tong Chua; Anutosh Chakraborty |
| A novel modular and miniature chiller is proposed that symbiotically combines absorption and thermoelectric cooling devices. The seemingly low efficiency of each cycle individually is overcome by an amalgamation with the other. This electro-adsorption chiller incorporates solely existing technologies. It can attain large cooling densities at high efficiency, yet is free of moving parts and comprises harmless materials. The governing physical processes are primarily surface rather than bulk effects, or involve electron rather than fluid flow. This insensitivity to scale creates promising applications in areas ranging from cooling personal computers and other micro-electronic appliances, to automotive and room air-conditioning. | ||||||

| A method is provided for cooling a high temperature superconductor such as an oxide superconductor to a lower temperature at a lower cost with a more simple system. A superconducting coil is attached to a cooling stage of a refrigerator. By immersing the superconducting coil on the cooling stage in liquid nitrogen, the superconducting coil is cooled rapidly. Then, the superconducting coil is further cooled by the refrigerator. By the cooling operation of the refrigerator, the liquid nitrogen is solidified. Thus, the superconducting coil is surrounded with solidifed nitrogen. The superconducting coil covered with the solidified nitrogen is further cooled by the refrigerator. In the superconducting coil cooled to a lower temperature and covered with solid nitrogen, quenching is suppressed to allow a higher current to be conducted. | ||||||
| 217 | Multi stage thermoelectric power generation | US653862 | 1996-05-28 | US5722249A | 1998-03-03 | Joel V. Miller, Jr. |
| A refrigerating system having multiple stages wherein each stage has a boiler for holding a solution of a first constituent being a gas dissolved in a second constituent being a liquid. The boiler communicates with a separator where the gas is separated from the liquid by the heat from the boiler and the gas is then passed to a condenser where it condenses to a liquid. The liquid first constituent passes to an evaporator. In one of the stages, the evaporating first constituent cools the region to be refrigerated in thermal contact with the evaporated of the respective stage. The gaseous first constituent then passes to an absorber where it dissolves in the second liquid constituent that has passed from the separator to the absorber. The solution of first and second constituents now passes to the boiler where the cycle is repeated. | ||||||
| 218 | Condensing system and operating method | US427816 | 1989-10-27 | US5040373A | 1991-08-20 | Michael A. Minovitch |
| A cryogenic condensing system is provided wherein the working fluid is paramagnetic and entropy reduction is accomplished by means of a magnetic field. Condensation is obtained by isentropically expanding partially compressed vapor into a thermally insulated vacuum chamber with a sufficiently large expansion ratio to supersaturate the vapor, a portion of which condenses spontaneously. That portion of the vapor which does not condense is drawn out of the condensing chamber and into the bore of a superconducting solenoid by magnetic attractive forces thereby maintaining the vacuum environment inside the chamber. The noncondensed vapor is magnetized and magnetically compressed inside the solenoid thereby reducing its entropy. Heat of magnetization is extracted by a non-magnetic turbine which converts the kinetic energy of the gas stream pulled into the solenoid into mechanical work. The low entropy vapor is removed from the solenoid by a compressor mounted inside the bore such that its thermodynamic state is returned to the preexpanded state outside the magnetic field. This vapor is mixed with previously condensed vapor having the same thermodynamic state and recycled back through the condensing expander to produce a constant flow of condensed working fluid. The system could be used for cryogenic engines using oxygen. | ||||||

| 220 | Regenerative fresh-air air conditioning system and method | US288159 | 1988-12-22 | US4938035A | 1990-07-03 | Khanh Dinh |
| A regenerative fresh-air air conditioning system moves ingoing and outgoing air through a building structure and includes an ingoing air portion wherein the ingoing air is filtered and then pre-cooled by a pre-cooling heat pipe. The ingoing air is then moved by a blower to an evaporator where the air is further cooled and a resulting condensate forms. The cooled air is then supplied to the building by a supply register. Outgoing air passes across a wet heat pipe which is wetted by the condensate from the evaporator and may also be wetted by condensate from the pre-cooling heat pipe. The outgoing air is then sub-cooled and mixed with fresh air by a fan which moves the mixed fresh and outgoing air across a condenser and exhausts the mixed air from the building structure. | ||||||
