The evaporator includes an evaporation tube through which the refrigerant decompressed in the expansion device flows, a coupling tube through a refrigerant heat-exchanged with the refrigerant of the evaporator flows, and a heat-exchange fin coupled to the evaporation tube and the coupling tube.05-07-2015
20150300709AIR-CONDITIONING APPARATUS - An air-conditioning apparatus includes a plurality of indoor units each located inside a building and at a position that enables the indoor unit to condition air, and a relay unit installed in a space not to be air-conditioned inside the building. The relay unit and each indoor unit are connected to each other via a first heat medium pipe in which a first heat medium such as water or brine flows. The relay unit accommodates therein a first refrigerant circuit including a compressor, a plurality of first intermediate heat exchangers that exchange heat between the first heat medium and refrigerant that performs a phase shift or turns to a supercritical state during operation, a plurality of expansion devices, and a second intermediate heat exchanger that exchanges heat between the refrigerant and a second heat medium, which are connected via a refrigerant pipe.10-22-2015
20150369532COOLER - A cooler includes an estimator. The estimator is configured to estimate a coolant temperature from a measurement value of the temperature sensor. The estimator is configured to determine a difference by subtracting an immediately preceding measurement value from a current measurement value, determine a correction value from the difference, and output an estimated value of the coolant temperature. The estimated value is obtained by adding the correction value to the current measurement value. The correction value is obtained by multiplying a gain by the difference. The gain is determined from a time constant, the gain is determined according to a flow rate of the coolant. The time constant is obtained when a transfer function of heat transferred from the coolant to the temperature sensor is modeled as a first order lag system.12-24-2015

20160033185AIR-CONDITIONING APPARATUS FOR VEHICLE - An air-conditioning apparatus for a vehicle includes a casing that an air inlet which communicates with an opening formed in a roof of a vehicle and through which air in the vehicle is formed in, and an apparatus main body that is installed in the casing and conditions the air, in the vehicle, which is sucked through the air inlet. A wiring through hole for passing a wiring cable extending from the apparatus main body through a space between the roof of the vehicle and the casing is formed in a bottom plate of the casing. The wiring cable is disposed so as to be passed through the space between the bottom plate and the roof of the vehicle via the wiring through hole from the apparatus main body and to extend into the opening from a position that is in the bottom plate and above the opening of the vehicle.02-04-2016
20160146496AIR-CONDITIONING APPARATUS - An air-conditioning apparatus includes a refrigerant circuit connecting a compressor, a first heat exchanger, a first expansion device, and a second heat exchanger. The compressor and the first heat exchanger are housed in a heat source unit, the heat source unit, houses a second expansion device provided at a location on a downstream side with respect to the first heat exchanger and on an upstream side with respect to the first expansion device, and the second expansion device and the first expansion device are connected via an extension pipe. The second expansion device reduces a pressure of refrigerant flowing into the extension pipe in cooling operation to cause the refrigerant to turn into refrigerant having a medium pressure and in a two-phase state, and the medium pressure is lower than a refrigerant pressure in a condenser and higher than a refrigerant pressure in an evaporator.05-26-2016
20220140420COOLANT SUPPLYING MODULE - A coolant supplying module is for supplying a coolant stored in a shared reservoir tank to an electrical component cooling circuit and a battery cooling circuit, and includes a main body connected to the shared reservoir tank, at least one valve mounting portion formed inside the main body to mount at least one valve device, at least one pump mounting portion formed inside the main body to mount at least one water pump, and a control portion mounted outside the main body and electrically connected to the at least one valve device and the at least one water pump.05-05-2022
