Abstract
The invention discloses a refrigerant tubing method for multi-split air conditioners, and belongs to the field of mounting of air conditioners. The positions of an outdoor unit and indoor units satisfy the following conditions: (1), when the outdoor unit is higher than the indoor units, the height difference between the indoor units and the outdoor unit is not more than 50m; (2), when the outdoor unit is lower than the indoor units, the height difference between the indoor units and the outdoor unit is not more than 90m; (3), when the height difference between the indoor units and the outdoor unit is not more than 30m, the indoor units are evenly mounted on two sides of branch pipes; (4), when the outdoor unit is higher than the indoor units in terms of placement position and the height difference between the both is more than 20m, an oil return turn is arranged every 10 meters on a gas pipe of a main pipe, lengths of horizontals straight-pipe sections between copper-pipe turnings and adjacent branch pipes are not less than 0.6m, length of a horizontal straight-pipe section between every two adjacent branch pipes is not less than 0.6m, and lengths of horizontal straight-pipe sections connected with the indoor units and positioned in rear of the branch pipes are not less than 0.6m. By the refrigerant tubing method, refrigerant tubing difficulty is lowered, and operation efficiency of the units is improved.
Description
Technical field
The invention belongs to air-conditioning installing area, be specifically related to a kind of multi-gang air-conditioner coolant piping method.
Background technology
At present, known multi-gang air-conditioner refrigerant tubing is copper pipe, and coolant piping is as the passage of air-conditioning refrigerant, and its effect is very important.
Along with the fast development of China's economic construction, people are also more and more higher to the pursuit of life taste, air-conditioning is comparatively general entering in Common People also, the quality that coolant piping is installed will directly determine the quality of air-conditioning, affect the operational efficiency of unit, serious even have influence on unit and can normally move, must arouse attention.
Summary of the invention
In order to make multi-gang air-conditioner operational efficiency higher, riding quality is better, the invention provides a kind of multi-gang air-conditioner coolant piping structure, this multi-gang air-conditioner coolant piping structure can be simplified coolant piping difficulty, make pipe arrangement distance, layout more reasonable, improve refrigeration (heat) effect of indoor set, improve the operational efficiency of unit.
Technical scheme of the present invention is: multi-gang air-conditioner coolant piping method, coolant piping overall length is not more than 1000 meters, pipe arrangement physical length is not more than 160 meters farthest, pipe arrangement equivalent length is not more than 190 meters (branch pipe reduced length is 0.5 meter of piping length of equal value) farthest, the first branch pipe is not more than 40 meters to pipe arrangement equivalent length farthest, off-premises station is during higher than indoor set, drop between indoor set and off-premises station is not more than 50 meters, off-premises station is during lower than indoor set, drop between indoor set and off-premises station is not more than 90 meters, drop between indoor set and indoor set is not more than 30 meters, interior machine is the both sides that are arranged on branch pipe of equalization as far as possible, when the riding position of off-premises station exceedes 20 meters higher than riding position and the drop of indoor set, on supervisor's tracheae, every 10 meters, an oil return is set curved, horizontal straight tube segment distance between copper pipe turning and adjacent branch pipe will be not less than 0.6 meter, horizontal straight tube segment distance between adjacent two branch pipes will be not less than 0.6 meter, the horizontal straight tube segment distance that connects indoor set after branch pipe will be not less than 0.6 meter.
The invention has the beneficial effects as follows, simplified coolant piping difficulty, make pipe arrangement distance, layout more reasonable, improve refrigeration (heat) effect of indoor set, improve the operational efficiency of unit.
The described physical length of pipe arrangement farthest refers to the length of the pipe arrangement of actual use when multi-gang air-conditioner is installed.
The described equivalent length of pipe arrangement farthest refers to while connecting due to central air-conditioning pipe arrangement and has branch pipe, therefore the length of branch pipe is folded to piping length, is exactly equivalent length, and each branch pipe reduced length is 0.5 meter.
Pipe arrangement equivalent length=pipe arrangement physical length+branch pipe reduced length.
