Top Mounting Cabinet Air Conditioner

Scope: electric equipment control box, battery compartment, and telecommunication equipment and other pertinent equipments, enclosed area climate control such as wireless communication cabinet, battery cabinet, industry control cabinet etc.

Features:

• Cooling capacity: 350W~1000W
• Refrigerant: R134a
• Digital control mode, can reach high accuracy.
• The unit can work perfectly from -40 to +50 Degrees Celsius.
• Keep the dust, oil fog and moisture from entering the internal of the equipments. IP23
• The structure design makes the installation more flexible. And the unit can be installed perfectly in the side or outside wall of the equipment 
• Totally solve dust and moisture contamination issues caused by ventilation
• Applicable for severe ambient environment, such as high temperature
• Using natural cooling technologies, energy efficient operation
• Widely used in telecommunications, broadcasting, electricity, automation and other industries out-door cabinet, IDC room cooling needs.
• The unit applications: electric equipment control box, battery compartment, and telecommunication equipment and other pertinent equipments, enclosed area climate control such as wireless communication cabinet, battery cabinet, industry control cabinet etc.
• The cabinet air conditioner is endothermic cooling through compression refrigeration.
• In the confined cabinet, the heat issued by the inside equipment is transferred to the outside.
• The high temperature, dust and other dirty gas outside the cabinet will not enter into the cabinet.
• Thus it solves a series of problems caused by the fans during its cooling.
• The temperature in the cabinet can be kept at an ideal level which ensures a stable running of the electronic equipment.  

Installation instruction:

• Don't use the equipment in the environments with more dust, oil moisture, corrosive or harsh air. Among them shall not exceed 55°C ambient temperature, and not lower than 0°C, humidity should not exceed 95%
• Use M6*10 screws fix flange on cabinet
• Drain cannot stress, after the installation must ensure smooth condensate drain
• Handling or moving the equipment , do not upside down, tilt and collision.  

Parameter Table:

Switch:

1.Power on, the fan of internal circulation will be normally open.  

2.Set the start temperature of chiller.(For example---18°C)

 When the temperature inside the cabinet is higher than the setting temperature, the chiller will be on; when it is lower than the setting temperature, the chiller will be off.

How to Determine Correct Model of Cabinet cooler 

Key Point---Calculating Heat Load for your Enclosure
To determine the correct model for your application, it is first necessary to determine the total heat load to which the control panel is subjected. This total heat load is the combination of two factors — heat dissipated within the enclosure and heat transfer from outside into the enclosure.

Steps of Calculating Btu/hr.:
1. First, determine the approximate watts of heat generated within the enclosure.  Watts x 3.41 = Btu/hr.

2. Then, calculate outside heat transfer as follows:
    a. Determine the area in square feet exposed to the air, ignoring the top of the cabinet.
    b. Determine the temperature differential between maximum surrounding temperature and desired internal temperature. Then, using the Temperature Conversion Table (below), determine the Btu/hr./ft.² for that differential. Multiplying the cabinet surface area times Btu/hr./ft.² provides external heat transfer in Btu/hr.

3. Add internal and external heat loads to get total heat load.
