Problems solved by technology

However, in the past, there has not been proposed an outdoor unit for a separate type air conditioner with a large horsepower.
In order to increase the capacity of the outdoor unit, while increasing the number of installed compressors, the capacity of the heat exchanger or accumulator must be increased. The equipment is well accommodated in the body of the outdoor unit, so as to effectively carry out maintenance on the accommodated equipment, etc.

Embodiment Construction

[0025] Next, an embodiment of the outdoor unit of an air conditioner according to the present invention will be described with reference to the drawings.

[0026] In Fig. 1, 1 represents the outdoor unit of 20 horsepower (hereinafter referred to as "ps") (hereinafter referred to as "main unit" for short); 3 represents the outdoor unit of 10 ps (hereinafter referred to as "subsidiary unit"). The main and auxiliary units 1 and 3 are connected to the indoor unit 51 through a refrigerant pipe 50 .

[0027] Regarding the "main unit" 1, the main unit 1 has three compressors, namely, a 10 ps rated compressor (scroll type) 15, a 5 ps rated compressor (rotary type) 17, and a power control mechanism. compressor (hereinafter referred to as "p / c compressor") 19. Explain about the p / c compressor 19 again, the p / c compressor 19 has a control port 19a on the cylinder (described later) for compressing refrigerant, if the high pressure valve 19b is open, high pressure is added to the control ...

Abstract

In an air conditioner in which plural outdoor units are connected to plural indoor units, at least one outdoor unit is provided with a compressor having a power control mechanism for inhibiting a part of a compression work, and the power of the compressor is made variable by controlling the power control mechanism. The outdoor unit is provided with two heat exchangers which are designed in a substantially U-shaped form, and disposed in a main body of the outdoor unit so that the opening sides thereof are confronted to each other, and the refrigerating elements which constitutes a refrigerant circuit and contains at least the compressor, an accumulator, etc. are disposed in a space which is surrounded by the two heat exchangers.

Description

technical field [0001] The present invention relates to a variable capacity air conditioner. Background technique [0002] As is well known, in general, a plurality of indoor units are connected to a plurality of outdoor units, and a compressor, a condenser, a pressure reducer, and an evaporator are connected sequentially to form an air conditioner (separate type air conditioner) that constitutes a refrigerant circuit. In such an air conditioner, it is conceivable to vary the capacity of the above-mentioned compressor according to the load. In this prior art, in order to vary the capacity of the compressor, a so-called inverter compressor that changes the capacity by changing the power frequency has been proposed. [0003] However, in the above-mentioned prior art, when an inverter compressor is used, the price is high, and at the same time, there are power frequency components that will bring noise to computers around the air conditioner, etc., and make capacitors (electri...
