| 20090071177 | Refrigerant Air Conditioner - A sufficient heating capacity can be displayed even in cold districts with atmospheric temperatures of −10° C. or less by improving the heating capacity in the refrigerant air conditioner much more than that of conventional gas injection cycles. | 03-19-2009 |
| 20090093569 | Novel Dispersant And Compositions Thereof - A composition comprising a particulate Solid, an organic medium and a compound with an alkyleneoxy compound with an inorganic acidic polar head group (Z), wherein the compound is defined by Formula (1) and salts thereof: U—(Y) | 04-09-2009 |
| 20090126375 | Air conditioner, refrigerant filling method of air conditioner, method for judging refrigerant filling state of air conditioner as well as refrigerant filling and pipe cleaning method of air conditioner - An air conditioner is arranged so as to be able to accurately judge a refrigerant filling state within the air conditioner regardless of environmental and installation conditions. The air conditioner has a computing section | 05-21-2009 |
| 20090158761 | REFRIGERATOR AND AIR CONDITIONER - A refrigerator has a coolant cooler for cooling a coolant at the entrance of a flow control valve, when the cooling amount in the coolant cooler is deficient as well as excessive. The refrigerator includes a compressor for compressing the coolant, a radiator for radiating heat from the coolant, a coolant cooler for cooling the coolant, a flow control valve for regulating the flow volume of the coolant, an evaporator for evaporating the coolant, and a heat-exchange-amount control for controlling the amount of heat exchanged in the coolant cooler. The coolant is circulated through the compressor, the radiator, the coolant cooler, the flow control valve, and the evaporator, in that sequence. | 06-25-2009 |
| 20100152903 | REFRIGERATING CYCLE APPARATUS AND OPERATION CONTROL METHOD THEREFOR - In a refrigerating cycle apparatus and control method thereof, a controller sets a high-pressure pressure target value from thermal load and temperature conditions based on refrigerant information that has been obtained from detectors, and controls at least one of a rotational frequency of a compressor, a degree of opening of an electronic expansion valve, a rotational frequency of an outdoor fan, or a rotational frequency of an indoor fan to match a high-pressure pressure to the high-pressure pressure target value that has been set. Here, a threshold value is set when the high-pressure pressure target value is set, and a method for setting the high-pressure pressure target value is modified depending on whether the high-pressure pressure is greater than or equal to the threshold value or less than the threshold value when the high-pressure pressure target value is decided. | 06-17-2010 |
| 20100192607 | AIR CONDITIONER/HEAT PUMP WITH INJECTION CIRCUIT AND AUTOMATIC CONTROL THEREOF - Heating equipment, including a first heat exchanger, a compressor, a second heat exchanger, and a first expansion valve that decompresses a refrigerant flowing from the second heat exchanger to the first heat exchanger, are connected so as to circulate the refrigerant. A third heat exchanger provides heat of the refrigerant flowing from the second heat exchanger to the first heat exchanger to the refrigerant flowing from the first heat exchanger toward the compressor. An injection circuit merges part of the refrigerant flowing from the second heat exchanger to the first heat exchanger with the refrigerant that is sucked by the compressor. An injection expansion valve is installed in the injection circuit and decompresses the refrigerant flowing in the injection circuit. A fourth heat exchanger is installed in the injection circuit to supply heat of the refrigerant flowing from the second heat exchanger toward the first heat exchanger to the refrigerant flowing in the injection circuit. | 08-05-2010 |
| 20100205987 | REFRIGERATION CYCLE APPARATUS - A refrigerant cycle apparatus comprising: | 08-19-2010 |
| 20110083456 | REFRIGERATION CYCLE DEVICE AND METHOD OF CONTROLLING THE SAME - A refrigeration cycle device | 04-14-2011 |
| 20110132019 | HEAT PUMP APPARATUS - A heat pump apparatus includes a refrigerant circuit in which a compressor, a condenser, expansion means, and an evaporator are serially connected. Condensation temperature detection means that detects a saturation temperature of the condenser, and evaporation temperature detection means that detects the saturation temperature of the evaporator are provided. Operation efficiency is estimated by a value obtained by dividing heating ability estimated from a detection value of the condensation temperature detection means by a difference between a detection value of condensation temperature detection means and that of evaporation temperature detection means or dissipation power estimated by the difference. | 06-09-2011 |
