Hello, the central air-conditioning site layout, the master had better be present. The specific participants are air conditioning construction project manager, decoration designer, decoration foreman and owner. The installation of central air conditioning is closely related to the interior design, which requires multi-party docking confirmation (the height of air conditioning installation position, the height of inner corner line and the height of reflective lamp slot). These problems will affect the decoration construction and the later use effect of air conditioning. Before the renovation of the new house, we have a process of design and decoration, and so does the installation of central air conditioning. The first thing the sales staff of the air-conditioning business should do is to go back to the renovated house to measure and check the structure of the house (specifically, to know the location of the indoor unit, the location of the outdoor unit, the decorated ceiling, the general piping situation, the orientation of the house, the thermal insulation of the house, the floor height difference, the arrangement of indoor beams, the indoor power supply situation, and the demolition of the wall structure), and then take the information back to the company's design budget department to design an optimized air-conditioning scheme, and then carry out a deep air-conditioning scheme with the owner. The main participants are air-conditioning design surveyors, owners, decoration designers and construction foreman (the best on site).
