摘要： PROBLEM TO BE SOLVED: To solve a problem that in a conventional cooling medium reheating type dehumidifying air conditioner, at passing through a head exchanger, the supersaturated state is released since cooled supersaturated air collides with heated air, water drip occurs and temperature unevenness is generated since blowing-out in the fully mixed state is impossible, or dehumidifying amount is largely affected by arrangement location of the heat exchanger since wind speed of a blower is not even, which greatly restricts design. SOLUTION: The heat exchanger is thermally divided, each of them is made as a heat exchanger for cooling and a heat exchanger for heating, and the heat exchanger for cooling is arranged on the upstream side to an air flow, while the heat exchanger for heating is arranged on the downstream side so that the entire air which has been cooled and dehumidified is reheated evenly.

摘要： PROBLEM TO BE SOLVED: To reduce a comsumption power energy and to cut a peak of power with a simple structure by circulating a refrigerant to a heat exchanger for heat exchanging the refrigerant with a thermal storage material, a user side pressure reducing unit and a user side heat exchanger, and cooling the refrigerant with the cold heat stored in the material at the user side exchanger. SOLUTION: In a refrigerant natural circulation cooling of cooling modes, a compressor 1 is stopped, and a cold heat stored as an ice in a thermal storage tank 99 is used for cooling in a cold heat thermal storage operation. Vapor refrigerant sent from two user side heat exchanges 8a, 8b is sent from uppermost parts to a thermal storage exchanger 6 through vapor piping 82 and an opening/closing valve 11 to radiate heat to a thermal storage material 98 in the tank 99 so that the refrigerant itself is condensed and liquefied. The liquefied refrigerant is fed from a lowermost part of the exchanger 6 to liquid extended piping 84 through a thermal storage pressure reducing unit 5 and an opening/closing valve 13. The fed refrigerant flows to the exchanges 8a, 8b through user side pressure reducing units 7a, 7b. Thus, the refrigerant natural circulation is conducted by using a temperature difference and gravity of the material 98.

摘要： PROBLEM TO BE SOLVED: To perform high-efficient operation through proper distribution of a refrigerant and refrigerator oil by a method wherein one end of a whole heat-exchanger incorporated in outdoor and indoor units is made to communicate with the lower end bottom part of a medium pressure receiver through an electronic expansion valve incorporated in a function unit. SOLUTION: Refrigerant gas discharged from compressors 1a and 1b flows in an oil separator 4 through discharge pipings 10a and 10b and flows in outdoor and indoor heat-exchangers 2a and 2z through a high pressure gas piping 8 and heat-exchange is effected thereat for liquefaction. A liquefied refrigerant is reduced in a pressure halfway by electronic expansion valves 14a and 14z and flows in a medium pressure receiver 5 through refrigerant liquid pipings 6a and 6z. The liquefied refrigerant flows in indoor-exchangers 2x and 2y through refrigerant liquid pipings 6x and 6y and electronic expansion valves 14x and 14y, and is heat exchanged with indoor air hereat for gasification. A gasified refrigerant flows in an equalizing oil tank 3, exchanges heat with a refrigerant in a medium pressure receiver 5 through heat-exchangers 21a and 21b, and returns to the compressors 1a and 1b.
