Abstract: PURPOSE:To make it possible to carry out the optimum system operation based on each horsepower by changing setting values including not only open air temperature, pipe length but also operation horsepower. CONSTITUTION:Both remote controllers 22a and 22b or one of the controllers are turned on so that the operation may start. Then, when outdoor air temperature is detected with an open air detector 9 while pipe length is decided with a pipe length detector 23. An operation horsepower detector 24 is adapted to decide the operation horsepower based on ON/OFF signals transmitted from the remote controllers 22a and 22b while the preset pressure detector 25 detects the setting high pressure predetermined based on open air temperature, pipe length and operation horsepower. Then, a pressure detector 8 detects a high pressure side pressure and a differential pressure computing element 26 computes the difference between the detected pressure and the setting pressure. A competence control decision means 27 is capable of controlling the frequency of an inverter 2, responding to the differential pressure and operating the optimum system operation.

Abstract: PURPOSE:To prevent a rise in a suction temperature, moreover an increase in a discharge temperature and protect a motor shaft from burning and a bearing from seizing by forming a ring-shaped refrigerant circuit which connects outdoor equipment with a plurality of indoor equipment consisting of an indoor side expansion valve and an indoor side heat exchanger and installing a radiation mechanism on the way of a high gas pressure bypass line. CONSTITUTION:When the horse power of indoor equipment is smaller than that of outdoor equipment, the circulation amount of refrigerant is increased excessively compared with the functional power of the indoor equipment, which lowers the suction pressure and generates frost, thereby degrading a cooling power. To comply with this, a high pressure gas bypass valve 3 is opened so that high temperature and high pressure discharge gas may be partially radiated by way of a heat exchanger 18 for high pressure gas bypass, allowing the discharged heat to be bypassed to the suction side as low temperature and high pressure gas. During heating operation, the circulation amount of refrigerant is too excessive against the functional power of the indoor equipment, which increases the discharge pressure excessively. To comply with this, the high pressure gas bypass valve 3 is opened so that the high temperature and high pressure discharge may be partially radiated by way of the heat exchanger 18 for high pressure gas bypass, allowing the discharged gas to be bypassed to the suction side as the low temperature and high pressure gas. This construction makes it possible to prevent the suction gas from being heated excessively and inhibit a rise in the suction temperature, and further an increase in the discharge temperature.

Abstract: PURPOSE:To improve the efficiency of the heating and achieve evenness in the temperature distribution in the room by providing a means of switching over the air outlet whereby a switchover is made between a lower outlet and an upper outlet according as a operation mode is turned to heating or cooling and also by providing at the lower outlet means of altering the direction of the ejected air whereby the air ejected can be sent in any direction as desired. CONSTITUTION:In heating, the indoor air sucked in through an inlet 36 undergoes heating by a heat exchanger 27 and then in sent into an air duct 33 by a blower 28; for the heating, the vane of a means-of-switching-over-the-air-outlet 30 is driven upward so that warm air flows downward through the air duct 33, through a lower outlet 32 into a space 39 under the room, through the space 39 and into the room through a vent 40; the warm air heats the flooring 38 of a double-floor structure evenly throughout from under as it flows thereunder, and heats the room 24 as it flows therein and is sucked into the inlet 36. In cooling, the vane of the means-of- switching-over-the-air-outlet 30 is driven downward so that cool air flows upward through the air duct 33, flows out through an upper outlet 31, and after impinging against the ceiling 23, cools the room 24 as it spreads downward therefrom and is subsequently sucked into the inlet 36.

Abstract: PURPOSE:To get a complete liquid phase refrigerant before an indoor side expansion valve and prevent a reduction in capability by a method wherein the degree of opening of an indoor expansion valve of an indoor one for an indoor device located at a lower position is set lower than a degree of opening of an indoor side expansion valve of an indoor device mounted at a higher position. CONSTITUTION:Since an indoor device 7a is mounted at a position higher than an indoor device 7b by about 10m, refrigerant before an indoor side expansion valve 14 shows a pressure drop of a height difference of water column of 10m. At a valve degree of opening correction means 20 of the indoor device 7b, a throttling amount (S) of the expansion valve by about a height difference of 10m is calculated and a degree of opening of the indoor side expansion valve 16 is always set to be low by S than a degree of opening of the indoor side expansion valve 14. Accordingly, since the pressure drop of the height difference is accommodated by S, the condition in the indoor side expansion valve 14 and that of the expansion valve 16 are same from each other and an over-cooling degree is controlled in such a way as the refrigerant state becomes a liquid phase. Accordingly, it can be prevented that a flow are of the indoor device mounted at a higher position is extremely throttled and no capability is outputted.

Abstract: PURPOSE:To offer a space of a moderate temperature without an uncomfortable feeling by calculating a thermal load in a room, detecting a temperature unbalance in a residential area, and regulating air spouting angles of an air conditioner based on comparing a set value with the calculated thermal load and the detected temperature unbalance. CONSTITUTION:A thermal load arithmetic device 26 calculates a thermal load based on signals from a suction temperature detector 19 and a room temperature setting device 18, and a temperature unbalance detector 27 detects a temperature unbalance along a floor and in a residential area based on temperature signals from a radiation temperature detector 20 and a circumferential temperature detector 24. An air spouting angle decision device 28 decides whether an air spouting parallel to a ceiling 4 or a downward air spouting toward a floor surface 17 based on signals from devices 26 and 27, and air spouting angle switch-over devices 29a and 29b change the angles of louvers 12a and 12b based on the signal from the device 28. Thereby, when the operation reaches a steady state with a temperature similar to a set value, and an air temperature change ratio becomes low, a horizontal air current is produced in a nonresidential area to produce a large convection current along the ceiling in the entire room.
