What is Cabinet Air Conditioner

As a professional manufacturer and supplier in China, Hisurp 2500W Cabinet air conditioners are devices used in control cabinets, machine tools, industrial assembly lines, and other industrial environments that require stable temperatures. The reason to buy 2500W Cabinet air conditioner is -- The electrical cabinet is full of electrical appliances, motion control and motor control equipment, which cannot work properly under high temperature or overheating conditions. High temperatures can cause electrical components to deteriorate, which in turn affects the life and performance of equipment. The electric cabinet air conditioner can ensure that the electric cabinet can run continuously and stably.

Application

Features

- The 2500W Cabinet Air Conditioner uses a general-purpose microcomputer controller for management and an easily identifiable LED display, making it possible to change and confirm the set temperature, thereby ensuring that the set temperature inside the cabinet is not affected by the outside temperature.
- The temperature difference between the cold air inlet and the air outlet is small, and the air volume is large. It slowly cools down while dehumidifying, and condensation occurs on the electrical components.
- The independent, sealed electrical cabinet completely isolates the air inside and outside the cabinet, achieving a dust-proof effect.

How to choose a model of cabinet air conditioner

Effective heat transfer surface area of electrical cabinets Body size (mm) W= H= D=	A=	Calculation of effective surface area (floor standing type) Negligible bottom surface (5 sides)
Average temperature around the electrical cabinet℃	T0	Calculation of temperature difference ΔT=T0-T1
Desired temperature inside the electrical cabinet℃	T1	Calculation of temperature difference ΔT=T0-T1
Coefficient of thermal conductivity Plain steel plate: 5.5W/㎡k Plastic sheet: 3.5W/㎡k	K=
Heat absorbed by the effective surface of the electrical cabinet (W) Qs=K x A x ΔT	Qs	When T0>T1, heat absorbed by the cabinet from outside,Qs>0 When T0<T1, heat discharged by the cabinet, Qs<0
Total heat generated by the devices inside the electrical cabinet (W)	Qi	Heat generated by the inverter (W) = capacity (kw) x 60
Safety factor	1.2
Calculation of the necessary cooling capacity Q0=1.2 x (Qs+Qi)	Q0

Example

There is an electrical cabinet box made of ordinary steel plate material with the external dimensions of 1 m long, 2 m high and 0.5 m thick. The heat generated by the internal heating elements of the box is 400 W. The temperature to be controlled inside the box is 30°C and the average temperature outside the box is 40°C. How much cooling capacity should be selected for the electric cabinet air conditioner?

Calculation

1.A=2x1x2+2x0.5x2+0.5x1=6.5㎡
2.ΔT=T0-T1=40-30=10℃
3.Qs=K x A x ΔT=5.5x6.5x10=357.5W
4.Q0=1.2 x (Qs+Qi)=1.2x(357.3+400)=909W
So, 1000W electrical cabinet air conditioner is recommended.
