Method and recovering refrigerant from an air conditioning system
A refrigerant service system according to the disclosure includes an inlet port configured to connect to an air conditioning system, a recovery valve fluidly connected to the inlet port, an accumulator fluidly connected to the recovery solenoid valve and including a pressure transducer configured to generate an electronic signal corresponding to a pressure in the accumulator, and a controller. The controller is configured to determine a target pressure for the accumulator based upon a condition of the refrigerant, obtain a current pressure in the accumulator from the pressure transducer, and to operate the recovery valve based upon the accumulator target pressure to control flow of refrigerant from the air conditioning system to the accumulator based upon the obtained current pressure and the determined target pressure for the accumulator..

Macpherson Engineering Inc.
Air conditioning indoor unit
An air conditioning indoor unit includes a casing having an air outlet, a horizontal blade, a coanda blade and a control unit. The horizontal blade changes an up and down direction flow of outlet air blown out from the air outlet.
Methods for operating heating, ventilation and air conditioning systems
A control method is for controlling a variable-speed direct gas-fired air-handling unit of a heating, ventilation and air conditioning system. The method includes sensing a make-up temperature of the system and comparing the sensed make-up air temperature to a make-up air temperature setpoint.
Solar air conditioning heat pump with minimized dead volume
A method and apparatus that reduces the dead volume in a heat engine or heat pump, such as a duplex stirling or vuilleumier cycle device, by nesting the components of the displacer and regenerator such that nearly all working fluid is purged from the interstices of the regenerator elements and all other working fluid spaces that are not involved in doing useful work at each portion of the cycle. Particularly, a more scalable and efficient method and apparatus for providing solar air conditioning or refrigeration by means of a heated cylinder that alternately pressurizes and depressurizes a separate cooling cylinder by directly transferring thermally induced pressure changes to that cooling cylinder at optimized times in the cycle, under the control of a numerically controlled actuation system that can cycle at a much lower rate than mechanically coupled or harmonically phased systems..
Vehicl air conditioning apparatus
There is provided a vehicle air conditioning apparatus that can prevent the amount of the refrigerant discharged from the compressor from reducing when an outside air temperature is low to achieve a heating performance required for a heating operation, and also can dehumidify the vehicle interior without deteriorating the heating performance during a heating and dehumidifying operation. The vehicle air conditioning apparatus includes: a heat released refrigerant expansion valve that decompresses the refrigerant discharged from the radiator during the heating operation and the first heating and dehumidifying operation; a gas-liquid separator that separates the refrigerant decompressed by the heat released refrigerant expansion valve into a gaseous refrigerant and a liquid refrigerant; and a bypass circuit that allows part of at least the gaseous refrigerant separated in the gas-liquid separator to flow into a section of the compressor through which the refrigerant being decompressed passes..
Hybrid heat exchanger
This disclosure presents a heat exchanger that comprises a header frame having end plates, a plurality of rows of finned hairpins, each extending through a cooling fin and each having ends extending through the end plates, and at least one finless hairpin having ends extending through the end plates. Additionally, a support sheet is coupled to the header frame and at least on finless hairpin extends through the support sheet and is supported thereby.
