摘要： PROBLEM TO BE SOLVED: To simplify control by minimizing the number of sensors and rationalize harmony between an indoor temperature and humidity. SOLUTION: An indoor wall surface temperature Tiwall is computed from a temperature Ti on the indoor side and a temperature To on the outdoor side only by an outdoor temperature sensor 7 to measure the temperature To on the outdoor side and a humidity sensor 6 to measure humidity Ts on the indoor side. By comparing a magnitude relation between a dew point temperature determined by the temperature Ti on the indoor side and the humidity Ts on the indoor side and the indoor wall surface temperature Tiwall, dehumidifying operation, cooling operation, and ventilation operation are switched and harmony between a temperature and humidity is properly controlled by a dew- point temperature basis.

摘要： PROBLEM TO BE SOLVED: To prevent generation of abnormal noise and instability of the refrigeration cycle by splitting a flow passage in which the refrigerant flows into a plurality of circuits in the vertical direction, and providing a riser pipe on an outlet pipe of a condenser located higher among a plurality of circuits to uniformly flow the refrigerant. SOLUTION: In an air conditioner in which a condenser is split into a plurality of circuits in the vertical direction, a riser pipe 17 is provided on an outlet pipe 15 of a condenser 11 located on an upper part of the air conditioner. The height and the diameter of the riser pipe 17 are set corresponding to the liquid head difference from the liquid head of a condenser pipe 12 arranged therebelow. Because the similar liquid head to that applied on an outlet pipe 16 of a lower condenser is applied to the refrigerant flowing from the upper condenser 11 into the outlet pipe 15 of the upper condenser by the riser pipe 17, the liquid outflow from the upper and lower condensers 11, 12 becomes uniform. Abnormal noise can be eliminated, and the refrigeration cycle with excellent balance can be formed irrespective of the difference in height of the condensers 11, 12.

摘要： PROBLEM TO BE SOLVED: To provide a detection method capable of detecting surely the composi tion of a circulating refrigerant, and a refrigerating apparatus which performs stabilized operation using the detection method. SOLUTION: In a refrigeration cycle which has a compressor 1, a condenser 2, a liquid receiver 5, an electronic expansion valve 3 and an evaporator 4 and seals a non-azeotropic mixed refrigerant, the temperature and the pressure of saturated refrigerant in the liquid receiver 5 are calculated, and the composition of refrigerant responding to the saturated refrigerant temperature and the saturated refrigerant pressure measured in the liquid receiver 5 is computed based on the relation of three elements comprising the saturated refrigerant temperature, saturated refrigerant pressure and refrigerant composition, which are predetermined, thereby detecting the refrigerant composition which circulates through the refrigeration cycle. There is provided a controller 8 which controls the rotary speed of an inverter-driven compressor based on the detected value thus detected and adjusts the opening control of an expansion valve 3.

摘要： PROBLEM TO BE SOLVED: To reduce amounts of refrigerant, miniaturize an accumulator, and reduce the cost by interposing in a liquid side connection pipe near an outdoor machine a parallel circuit including a check valve which allows refrigerant to flow therethrough only at the time of a cooling operation and a throttle which throttles refrigerant at the time of a heating operation. SOLUTION: A parallel circuit 20 including a check valve 21 which allows refrigerant only at the time of a cooling operation and a throttle 22 which throttles refrigerant at the time of a heating operation is interposed in each of liquid side connection pipes 11A, 11B near respective indoor machines A, B. In an heating operation, refrigerant circulates through a refrigerant circuit and is condensed and liquefied at indoor heat exchangers 7A, 7B, and the liquefied refrigerant is throttled when it passes through a throttle 22 of the circuit 20, whereby the refrigerant is formed into a gas-liquid phase and flows through the pipes 11A, 11B into an outdoor machine O. In a cooling operation, refrigerant formed into the form of gas-liquid phase by being throttled at expansion valves 5A, 5B of the machine O passes through the pipes 11A, 11B and into the machines A, B through the check valve 21 of each of the circuits 20.

摘要： PROBLEM TO BE SOLVED: To prevent the drop of an evaporator inlet temperature and to prevent the decrease in the performance of an outdoor heat exchanger by providing a liquid reservoir on the way of the refrigerant channel of the exchanger, and providing a throttle at the connecting part of the reservoir to the refrigerant channel of the side to become the inlet of the exchanger at the time of heating. SOLUTION: Since the liquid refrigerant condensed by a first outdoor heat exchanger at the time of cooling is recovered by a liquid reservoir 5 via a connecting tube 6, the heat transfer is not stopped due to the reduction in the heat transfer area caused by the storage of the condensed refrigerant in the exchanger 3. At the time of heating, the refrigerant throttled and expanded in a throttle mechanism 8 is partly evaporated in a second outdoor heat exchanger 4, dropped at the pressure due to the passage through a reduced- diameter connecting tube 7, introduced to the exchanger 3 via the reservoir 5 and evaporated. The drop of the inlet refrigerant temperature of the reservoir 5, i.e., the exchanger 3 is prevented by the pressure drop. Accordingly, the high heat transfer performance can be maintained.
