HVAC PLC Control Cabinet High Compatibility Centralized Management
Product Describe:
1. Large shopping malls/centers: Control the air conditioning units on different floors and areas (such as shops, corridors, and courtyards), automatically adjust the temperature according to the density of people flow (such as 18-26 ℃ in summer and 20-24 ℃ in winter), and link the fresh air system to supplement fresh air, while monitoring the operation status of equipment (such as fan and pump failure alarms).
2. Office Building/Office Building: Automatically start and stop air conditioning during office hours (such as 9:00-18:00), implement "temperature control in different time periods" through PLC programming (such as preheating in the morning and cooling down before leaving work), and support linkage with access control and lighting systems (such as automatically reducing air conditioning load when there is no one in a certain area).
3. Hotel/Hospital: The hotel rooms are controlled by a PLC cabinet to achieve linkage between "guest check-in - start air conditioning" and "check-out - turn off the host"; Hospitals need to accurately control the temperature and humidity of operating rooms and wards (such as operating room temperature of 22-25 ℃, humidity of 40% -60%), and ensure the stable operation of air filtration systems.

IP Grade:
IP54 / IP55 / IP65 / IP66
Suggestion:
1. Space & Layout
Match cabinet dimensions to installation space, leaving 10-15% clearance for operation and heat dissipation. Opt for compact/wall-mounted designs in tight areas.
Arrange components by weight (heavy devices at the bottom) and function (separate power/control zones) to avoid overcrowding; maintain ≥50mm spacing for cooling.
2. Environment Adaptation
Use IP54+ enclosures for dusty/humid areas; add fans or dehumidifiers for extreme temperatures. Choose 304 stainless steel for outdoor use.
3. Expandability & Safety
Reserve 10-20% extra space for future upgrades. Include communication ports (Ethernet, RS485) for system integration.
Add emergency stops and interlocks (power-off when door opens) for safety.
