Description

[Detailed description of the invention] (a) Field of industrial application This invention relates to an outdoor unit of a refrigeration system used in a separate air conditioner or a refrigerator in a show case.

(b) Prior art Utility Model Publication No. 59-14679 discloses an outdoor unit with multiple blowers, in which one blower is set at high speed and the other blower is set at low speed in order to reduce the humming noise caused by the blowers. It is presented in the official bulletin.

(c) Problems to be solved by the invention In order to reduce the size of outdoor units, refrigerant containers such as gas-liquid separators that separate low-pressure refrigerant into liquid and gas and liquid receivers that store high-pressure liquid refrigerant are replaced with heat exchangers. When installing a refrigerant container in a ventilation room with a blower and a blower operating at high speed, if a refrigerant container is installed close to the blower in the ventilation path of the blower, the refrigerant container will greatly disturb the air near the blower, causing a rustling noise. It has been found.

The present invention provides an outdoor unit for a refrigeration system that solves these problems.

(d) Measures to solve the problem In this proposal, a refrigerant container is installed in the ventilation path of a blower that operates at low speed among multiple blowers.

(E) Effect Since the blower is operated at low speed, the speed and volume of the outside air flowing around the refrigerant container is low, and the wind near the blower is not disturbed by the refrigerant container so much, so there is no risk of rustling noise. few.

(F) Embodiment To explain based on the drawings, 1 is an exterior body of an outdoor unit consisting of an outer box 3 having an intake port 2 and a front panel 5 having a discharge port 4. A partition plate 6 separates the ventilation chamber 7 from the machine. Inside the ventilation chamber 7, there is an L-shaped heat exchanger 9 along the intake ports 2 on the back and sides, and a support leg 10 facing the heat exchanger.
The compressor 1 is connected to the heat exchanger 9 and the compressor 13 in the machine room 8.
A refrigerant container 14 that acts as a gas-liquid separator for separating the low-pressure refrigerant sucked into the refrigerant 3 into liquid and gas is built in.
It is mounted at a position close to the low-speed lower blower 12.

The outdoor unit of the present invention is constructed as described above, and when the air conditioner is in operation, the outside air flows through the intake port 2 - heat exchanger 9 - discharge port 4 due to the rotation of both blowers 11 and 12. The blower 11 is at high speed,
Since the lower blower 12 is rotated at a low speed, the wind speed and air volume are lower than in the upper half of the blower chamber 7, and the wind near the lower blower 12 flows into the refrigerant container 14.
It is not disturbed that much, and for this reason,
It has been confirmed through experiments that there is little risk of rustling noise occurring.

Note that, unlike the above embodiment, when the upper blower 11 is set at low speed and the lower blower 12 is set at high speed, the refrigerant container 14 may be attached to the upper side of the support leg 10 and brought close to the blower 11.

Further, the refrigerant container 14 may be a liquid receiver or a compressor 13 that stores high-pressure liquid refrigerant. Also, blowers 11, 12
There may be three or more, and there may be three or more blowers 11, 12.
It is also possible to use an outdoor unit with a top vent facing upwards.

(g) Effects of the invention According to this invention, the refrigerant container is installed in the ventilation path of the blower that is operated at a low rotation speed among the multiple blowers, so the outdoor unit can be made smaller and the generation of rustling noise can be reduced. can be reduced.
