摘要： PURPOSE:To prevent discharge of a large quantity of refrigerant into the atmosphere in the case of air purging and to omit an operator for monitoring the air purging. CONSTITUTION:The separate type air conditioner comprises a gas discharger 60 having a valve disc 63 for opening/closing a gas discharge port 62 at an upstream side of a gate valve 3 mounted at a connecting end of a refrigerant system of an outdoor unit, and driving means 64, 67, 68, 69 for automatically driving the disc 63 of the discharger 60 when a predetermined time is elapsed after air purging is started to close the port 62.

摘要： PURPOSE:To eliminate a problem of installation and reduce noise join a room by arranging a humidifier of an air conditioner comprising an outdoor unit and an indoor unit out of the room. CONSTITUTION:In an air conditioner comprising an outdoor unit 1 and an indoor unit 2, a humidifier device 3 comprising a water feeding tank 31 and a pump 32 for sending water in the tank 31 is installed out of a room, water from the pump 32 is sent to a water sucking element 35 in the indoor unit 2 so as to humidify the water sucking element 35. In addition, water fed from the pump is dispersed into an indoor heat exchanger in the indoor unit.

摘要： PURPOSE:To increase the velocity of high temperature air flow for allowing it to reach the distance and to be distributed in a room by a method wherein the air flow of a room fan is increased when high temperature air blow state is established. CONSTITUTION:The blow air temperature detected by a blow air temperature sensor 14 is input to a comparator 31 to compare it with the set temperature input from a blow air temperature setting device 32. When the blow air temperature rises above the set temperature of 65 deg.C, the comparator 31 outputs a signal to a timer 33 and a room fan rotating speed decision device 28. Then, the timer 33 begins to count, and the room fan rotating speed decision device 28 decides to increase the rotation speed of a room fan 11. The decision is input to a variable motor 8 through an output device 30 to operate the room fan 11 at a high speed. As the air flow of the room fan is increased during high temperature air blow operation, the range of the air flow extends and the high temperature air is distributed in a room.

摘要： PURPOSE:To facilitate a piping connecting operation and to compactly form a finish with beauty by forming an angle formed between piping outputting directions of two operation valves of piping connectors of an outdoor unit at an acute angle. CONSTITUTION:Pipings 14, 18 are so mounted as to form piping outputting directions at an acute angle theta. That is, the pipings 14, 18 are formed at an included angle of an acute angle, and naturally brough into contact with one another near a top of the acute angle theta. Accordingly, even if they are wound with a tape 17 and bundled, particular bent does not occur at the pipings 14, 18, its width W1 is small, can be started to be wound from a position near an operation valve 1, and a faworable external appearance is obtained without difficulty. Thus, since both the pipings can be brought into close contact with one another and bundled at a position near the valve merely by slightly small bending, taping of the piping is facilitated and its finish becomes beautiful.
