A unit installation tool facilitates installation of a unit of a separate type air conditioner on a vertical member, preventing exposure of conduit to the elements, and improves the appearance. The tool has a yoke fitted to the vertical member with bolts, and a support part extended forward from the yoke, for mounting the upper part of the back side of the unit on its leading end. The mounted unit is supported at an upward position by a specified extent from the support part. A conduit space is formed on the support port between the supported outdoor unit and the yoke or the vertical member on which it is mounted.

Device for fitting outdoor unit of separate type air conditioner

The present invention has an object to provide a most preferred power-source covering device for an outdoor unit of an separate-type air conditioning systems, which is adapted to reduce vibration during the operation of the air conditioning system and heat conduction to a power cord from a pipe and a pipe connection valve. A power-source cover,is disposed to cover a terminal plate,for electrical interconnection between an indoor unit and an outdoor unit,via a power cord,, and a pipe connection valve,interconnecting the indoor unit and the outdoor unit,via a pipe,thereby forming a refrigerant circuit. The power-source cover,includes an opening,which is located above the pipe connection valve,and through which the power cord,connected to the terminal plate,is led out.

Power-source covering device for an outdoor unit of a separate-type air conditioning systems

Separate type air conditioner

Outdoor unit of separate type air conditioner

The constitution has (a) an outdoor unit, and (b) an indoor unit including a wind circuit unit having an air suction port, a heat exchanger and blowing means, an air stream control unit having an air diffuser and air stream control means, and an electrical unit having an electric control device and an electric circuit. At least one of the wind circuit unit, the air stream control unit, and the electrical unit is formed separately, and the one unit and the remaining units of the plurality of units are mutually assembled integrally to form the indoor unit. The indoor unit composed of the wind circuit unit, air stream control unit, and electrical unit possesses a front surface having a continuous pattern. In this constitution, it is possible to obtain an indoor unit of an air conditioner having such effects as excellent appearance, small number of parts, enhanced ease of disassembling, excellent working efficiency in mounting, and excellent working efficiency in repair service. Moreover, in model changeover, by modifying the individual units of the wind circuit unit, air stream control unit and electrical unit according to the purpose, restyling is easier. Hence, expenses for making dies for producing the units are saved, so that the manufacturing cost is reduced.

Separate type air conditioner and assembling method of indoor unit

A unit-type air conditioner has an out-door portion which has an out-door heat-exchanger, an out-door fan opposing the out-door heat exchanger and an air guider having an orifice defining the passage of air from the out-door fan and the out-door heat exchanger. The center of the circle of a slinger ring attached to the out-door fan is slightly offset from the center of the circle of the orifice such that the circle of the slinger ring is offset from the center of the orifice in the direction in which the slinger ring scoops condensate water generated in the air conditioner. Part of the condensate water scooped by the slinger ring is sprayed to the out-door heat exchanger so as to be evaporated by the heat generated in the heat-exchanger, while the remaining part of the condensate water collides with the wall of the orifice so as to be returned to a drain pan. Consequently, undesirable springing of condensate wall from out-door air suction openings is avoided.

Condensate water disposal arrangement for unit-type air conditioner

A control box 6 of an air conditioner at the front part of the body has two compartments 6A, 6B parted by a partition plate 7. One compartment 6A is for receiving lead wires 2 which connect electric components with a compressor motor and a fan motor, and the other compartment 6B is for containing electric parts. The lead wires 2 are folded once in the compartment 6A. and again folded at the rear end of the partition plate 7. By such twice folding of the lead wires and cramping them at the rear end of the partition plate 7, damaging of electric components by the lead wires is prevented.
