4. Installation precautions
1.Plan ahead: During the hydropower transformation stage, it is necessary to determine the air conditioning plan and reserve pipeline locations.
2.Outdoor unit location: Ensure good ventilation and ≥3 meters away from bedroom windows
3.Ceiling height: The indoor unit requires 25-30cm of installation space
4.Condensate drain: The slope should be ≥1% to avoid backflow
5.Acceptance criteria: Operating noise detection, temperature uniformity test, water leakage inspection
5. Frequently Asked Questions
Q: Does central air conditioning consume more electricity than ordinary air conditioning?
A: Inverter central air conditioners are more energy-saving in long-term use scenarios. Split-type central air conditioners may be more economical for short-term use.
Q: Can central air conditioning be installed with a floor height of 2.7 meters?
A: Yes, choose an ultra-thin indoor unit (thickness 18-20cm) and match the partial ceiling design.
Q: Can old houses be retrofitted with central air conditioning?
A: It is necessary to meet the ceiling modification conditions. It is recommended to choose a model with adjustable refrigerant pipe length.
From the above analysis, we can see that choosing central air conditioning requires comprehensive consideration of factors such as house structure, usage requirements, and budget. It is recommended that consumers conduct professional heat load calculations before purchasing and choose a service provider with formal installation qualifications to ensure the best use experience.
