RenovationIn the planning of air conditioning, many household types encounter difficulties with external space shortages: multiple rooms require independent air conditioning, but only individual air-conditioning slots are reserved by developers. A number of owners would consider setting up multiple part-air-conditioning units in the same slot. This option could not be limited to sizes. It would require integrated ventilation and heat, structural weighting, maintenance, air flow interference, and a five-dimensional assessment of property regulation, any of which would leave a risk of long-term use。
Step 1: recognition of property norms as a precondition. Air conditioners in most sub-regions belong to public areas outside the building, and the number, form of installation, stub modifications and changes to the leaves are regulated. Some subdistricts are directly prohibited from stacking a number of aircraft in the same slot, as well as from cutting and removing the original leaves. Renovation management agreements must be consulted during the pre-renovation period, and the pre-communication installation programme must be communicated in advance, so as to avoid being required for modification and demolition upon completion. The programme did not meet management requirements until equipment arrived。
Step 2: physical space measurement, accounting for ventilated heat. The out-of-air air conditioners are the most prone to heat-back short circuits, relying on continuous air currents to take heat away and multiple out-of-air co-locations. In short, a hot wind blowing out of an external aircraft can be sucked in by another external aircraft next to it, resulting in continued high temperatures, cooling decay, rising energy consumption, and frequent hot weather protection stops. General installation requirements: a 50 cm barrier-free space is reserved for the exterior and a 15 cm gap between the back and the venting position. When multiple externals are set in rows, the machine must also leave a gap of 20 cm or more between the machines; up-to-down stacking options, at the bottom of the upper and down-to-tops, suggest a space of 30 cm or more, with the upper-to-down vents having to be placed in the wrong place and not in the right place. If the space is heavily enclosed with closed leaves, and the self-ventilating resistance is excessive, the post-heating conditions will deteriorate even further with multiple externals. Such slots, even when sizes are available, do not recommend the placement of multiple external aircraft. The measurements shall be based on the net internal size of the space, less the shelf, pipe, and heat-dispersion reserve space, and then match the outside captain's width to the outer overpack size。
Step 3: evaluate structural weights and select a reasonable installation option. The external weight of single dac units is approximately 25 to 40 kg, and the total load will increase significantly with multiple overlays. The bearing capacity of the space concrete plate and wall is the safety floor. There are three ways to mainstream the market:
(b) aligning: when horizontal space is sufficient, priority is given to loads spread over the floor of the slot, the stress is the most stable, the repairs are easier and the flow of air is relatively small; the disadvantage is that the space width is high. Up and down double racks stacked: scenes suitable for a sufficient altitude and insufficient width. An additional, dedicated double support frame must be selected, which cannot be fitted with an ordinary simple corner iron. The swelling bolts shall be fixed at the base of solid concrete and shall not be fixed on the outer wall to protect the layer and light bricks. The stand needs to be protected from rust and prolonged protection from rain erosion. Spoiling staggers: disconnected installation using wall stratums to the outside, reduced upper- and lower-flow interference, and higher demands on the wall's body。
In either case, civil servants could be consulted to assess the carrying capacity of the floors of the aircraft and to eliminate the security risks associated with overloading。
Step 4: preserve space, pre-empt noise overlap. Exterior aircraft need to be cleaned, refrigerated and electrically controlled. If the gap between external aircraft is small and the manpower and tools cannot be reached, later maintenance will be significantly more difficult and maintenance costs will increase. When designing the seat layout, at least one side is kept with a fully operational overhaul face. With regard to noise, multiple compressors are operating simultaneously, and noise has a cumulative effect. The outer side is equipped with a de-shocking pad to reduce the amount of vibration that passes to the wall; the outer side of the air vents avoids, as far as possible, adjacent household windows and their own bedrooms and reduces routine noise interference。
Step 5: rational choice of air conditioners in comparison to options. It is not the only solution to place multiple partitions in the same slot. Multi-line (one towed multi-central air conditioner): the entire system is only one external machine, ventilated to the slots, less heavy pressure, and the external surface is clean; however, the prior period is more expensive and the construction of indoor pipes is demanding. The advantage of the branch machine is that it operates independently of one station and that one malfunction does not affect the use of the other room, but the disadvantages are obvious when space is insufficient。
There are multiple external aircraft installed at individual locations, space is only basic, ventilation and structural security are at the core. Priority is given to identifying property requirements, measuring them on site, surveying the current environment by air conditioners on site, and determining layout options. The renovation phase is planned in such a way as to avoid a series of problems with air conditioning cooling, acoustic noise and safety hazards。
