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 (ပေါက်ကွဲဒဏ်ခံ လေအေးပေးစက်) transfers from a colder to a warmer object per unit time. The nominal cooling capacity typically corresponds to an indoor အပူချိန် of 27℃ and an outdoor temperature of 35℃. သို့သော်, 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 (ဒဗလျူ) or kilowatts (kW). သို့သော်, in the realm of explosion-proof air conditioning, the traditional unit of kilocalories per hour (kcal/h) is still prevalent. ထို့ အပြင်, 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 နာရီ.

Heating Capacity:

The heating capacity represents the heat generated by the ပေါက်ကွဲဒဏ်ခံ လေအေးပေးစက် (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.
