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.

Temperature Conversion Table
Temperature Differential ° F	Btu/hr/ft.2
5	1.5
10	3.3
15	5.1
20	7.1
25	9.1
30	11.3
35	13.8
40	16.2

Example:     Internal heat dissipation: 650 Watts or 2216 Btu/hr.     Cabinet area: 40 ft.2     Maximum outside temperature: 110°F     Desired internal temperature: 95°F The conversion table (above) shows that a 15°F temperature differential inputs 5.1 Btu/hr./ft.2 40 sq. ft. x 5.1 Btu/hr./ft.2 = 204 Btu/hr. external heat load. Therefore, 204 Btu/hr. external heat load plus 2216 Btu/hr. internal heat load = 2420 Btu/hr. total heat load or Btu/hr. refrigeration required to maintain desired temperature. In this example, the correct choice is a 2500 Btu/hr. Cabinet Cooler System.
