062172000 | Air compessor, cooler and expander | 7 |
20080196425 | Method for evaluating refrigeration cycle performance - The present invention discloses a method for field testing refrigeration cycle equipment to evaluate condenser and evaporator performance. | 08-21-2008 |
20080264084 | PRESSURIZED CLOSED COOLING SYSTEM - An aircraft air conditioning system includes an air supply system (engine bleed or cabin air compressor taking ambient air and pressurizing it at or above cabin pressure) and a cooling system (air cycle or vapor cycle cooling packs to reject heat outside the vessel). These systems can exist as independent systems or combined into a single unit. Air supply and cooling are powered from either engine bleed air or electric power. In order to increase the airflow through the cabin, some cabin air is re-circulated and mixed with fresh air from the air supply system. | 10-30-2008 |
20120180509 | LOW PRESSURE BLEED ARCHITECTURE - A bleed air conditioning system within an aircraft including a low-pressure bleed air line and a high-pressure bleed air line. The system includes an air-to-air heat exchanger and an un-cooled bleed air line to connect the air-to-air heat exchanger to the low-pressure bleed air line and the high-pressure bleed air line. The un-cooled bleed air line carries a flow of un-cooled bleed air from at least one of the low-pressure bleed air line and the high-pressure bleed air line to the air-to-air heat exchanger. The system also includes a cooled bleed air line connected to the air-to-air heat exchanger for carrying cooled bleed air from the air-to-air heat exchanger and a low-pressure bypass line connecting the low-pressure bleed air line to the cooled bleed air line, bypassing un-cooled bleed air from the low-pressure line around the air-to-air heat exchanger to the cooled bleed air line. | 07-19-2012 |
20120192580 | Apparatus and Methods for Regulating Material Flow Using a Temperature-Actuated Valve - One embodiment of the present invention is a gas discharge system utilizing a temperature-actuated valve. The temperature-actuated valve uses a temperature-measuring device to sense the temperature of the natural gas after it pass through an expansion valve and after leaving a heat exchanger inside the discharge station. This temperature-measuring device sends a signal to a valve that is automatically actuated. If the temperature of the gas is too low, the valve is tightened, increasing the residence time in the heat exchanger and increasing the gas temperature. If the gas temperature is too high, the valve is opened, reducing the residence time in the heat exchanger, decreasing gas temperature. Using this temperature-actuated valve to control the temperature of a wet gas discharge station is also disclosed. | 08-02-2012 |
20130133348 | BLENDED FLOW AIR CYCLE SYSTEM FOR ENVIRONMENTAL CONTROL - An aircraft air provision system includes a power turbine that receives bleed air at a first pressure and provides rotational energy to a shaft and outputs output air at an intermediate pressure. The system also includes a compressor coupled to the shaft that receives input air at a second pressure that is lower than the first pressure and outputs compressed air having a pressure equal to the intermediate pressure and a mix chamber coupled to outputs of both the power turbine and the compressor where the output air and the compressed air are mixed. The system also includes a cooling turbine coupled to the shaft and that is in fluid communication with an output of the mix chamber. | 05-30-2013 |
20160054034 | CHILLER SYSTEM - A chiller system is provided. The chiller system may include a plurality of chillers, each of which may include a compressor, a condenser, and an evaporator, and a controller that controls the plurality of chillers. The controller may determine an expected load and a chiller to be operated of the plurality of chillers on the basis of the determined expected load to operate the determined chiller. | 02-25-2016 |
20160084511 | AIR-CONDITIONING SYSTEM - Maximum evaporating temperature setting values and minimum evaporating temperature setting values in an indoor heat exchanger and a ventilator cooler are determined in accordance with outdoor air temperature and humidity, evaporating temperature setting values in the indoor heat exchanger and the ventilator cooler are set to be between the respective maximum evaporating temperature setting values and the respective minimum evaporating temperature setting values, and evaporating temperatures in the indoor heat exchanger and the ventilator cooler are controlled so as to be the respective evaporating temperature setting values. | 03-24-2016 |
