| 20100107681 | HEAT EXCHANGER AND REFRIGERATION CYCLE APPARATUS - Heat exchangers | 05-06-2010 |
| 20100170273 | REFRIGERATING AND AIR CONDITIONING APPARATUS - In a range of a wind velocity of 0.5 to 3.5 (m/s) in a refrigeration cycle, when combining absorbent having a small dependency on the wind velocity and the refrigeration cycle, it is not possible to vary dehumidification capability by changing the wind velocity and matching with an actual load is poor. In a refrigerating and air conditioning apparatus having a refrigerator | 07-08-2010 |
| 20100282455 | HEAT EXCHANGER AND MANUFACTURING METHOD OF THE SAME - A heat exchanger is used which has heat transfer tubes acting as flow paths of a refrigerant and metal fins having pores opened inward from the surfaces thereof for adsorbing and desorbing moisture in air within the range of a relative pressure of 0.1 to 0.9 so as to transfer heat of the heat transfer tubes to air, wherein the pores have a diameter of 1 to 20 nm and a depth of 1 to 100 μm. | 11-11-2010 |
| 20130180278 | REFRIGERATING APPARATUS - A refrigerating apparatus includes a high temperature side first cycle; a high temperature side second cycle; a low temperature side cycle in which carbon dioxide is used as a refrigerant; a first cascade condenser and a second cascade condenser, which each exchange heat between a high temperature side refrigerant and a low temperature side refrigerant; and a control unit lowering an evaporation temperature of a high temperature side evaporator in correspondence to the flow of the low temperature side refrigerant. | 07-18-2013 |
| 20140027524 | HOT WATER SUPPLY SYSTEM - A hot water supply system includes a hot water storage tank configured to store hot water, a plurality of temperature sensors that are installed in the height direction of the water storage tank and that detect temperatures at their installed positions, a main-unit-side hot water supply device that heats hot water in the hot water storage tank, a sub-unit-side hot water supply device, a main-unit-side control board equipped with control means that controls the corresponding hot water supply device, and a sub-unit-side control board. Signals sent from the temperature sensors are input in a distributed manner among the main-unit-side control board and the sub-unit-side control board, and each of the control boards are communicably connected to each other by a transmission line. | 01-30-2014 |
| 20140083124 | REFRIGERATION APPARATUS - A refrigeration apparatus includes a high-temperature side circulation circuit, a low-temperature side circulation circuit, a cascade capacitor, and control means. The high-temperature side circulation circuit forms a refrigerant circuit in which a high-temperature side compressor, a high-temperature side condenser, a high-temperature side expansion device, and a high-temperature side evaporator are connected by a pipe. The refrigerant circuit allows a high-temperature side refrigerant to circulate therethrough. The high-temperature side refrigerant has a carbon-carbon double bond in its molecular structure. The high-temperature side compressor has a variable discharge capacity and is configured to discharge the high-temperature side refrigerant. The low-temperature side circulation circuit forms a refrigerant circuit in which a low-temperature side compressor, a low-temperature side condenser, a low-temperature side expansion device, and a low-temperature side evaporator are connected by a pipe. The refrigerant circuit allows a low-temperature side refrigerant to circulate therethrough. The low-temperature side refrigerant contains carbon dioxide. | 03-27-2014 |
