Explosion-Proof Air Conditioning Cooling Capacity and Heating Capacity

The cooling and heating capacities are pivotal technical metrics for explosion-proof air conditioners and are the primary parameters consumers should evaluate when selecting an air conditioner. Understanding the physical implications of the unit’s cooling/heating capacity and its appropriate room area coverage is essential.

Cooling Capacity:

Referred to as the load, cooling capacity is the heat that the refrigeration machine (explosion-proof air conditioner) transfers from a colder to a warmer object per unit time. The nominal cooling capacity typically corresponds to an indoor temperature of 27℃ and an outdoor temperature of 35℃. However, this capacity decreases if the outdoor temperature falls below 7℃ or exceeds 35℃. According to national standards, the measured cooling capacity must not be less than 95% of the nominal value specified on the nameplate.

In the International System of Units (SI), cooling capacity is denoted in watts (W) or kilowatts (kW). However, in the realm of explosion-proof air conditioning, the traditional unit of kilocalories per hour (kcal/h) is still prevalent. Additionally, some countries use the ton of refrigeration as a unit, representing the cooling needed to freeze 1 ton of 0℃ water into 0℃ ice over 24 hours.

Heating Capacity:

The heating capacity represents the heat generated by the explosion-proof air conditioner (electric heating type) or transferred from external warmer air to the interior (heat pump type) over time. This capacity is a critical performance index for both heat pump and electric heating-type explosion-proof air conditioners, akin in significance to cooling capacity.
