Understand the unit conversion relationship of masana’antu chiller cooling capacity to facilitate calculation results

The conversion relationship of various cooling capacity units is as follows:

1. 1Kcal/h (kcal/hour)=1.163W, 1W=0.8598Kcal/h;

2. 1Btu/h (British thermal unit/hour)=0.2931W, 1W=3.412Btu/h;

3. 1USRT (U.S. cold tons)=3.517KW, 1KW=0.28434USRT;

4. 1Kcal/h=3.968Btu/h, 1Btu/h=0.252Kcal/h;

5. 1USRT=3024Kcal/h, 10000Kcal/h=3.3069USRT;

6. 1hp=2.5KW (applicable to air-cooled industrial chillers), 1hp=3KW (applicable to water-cooled industrial chillers).

ra’ayi:

1. The “horse” used here, when used in power units, is expressed by Hp (imperial horses) or Ps (metric horses), also known as “horsepower”, 1Hp (imperial horses) = 0.7457KW, 1Ps( Metric) = 0.735KW;

2. Under normal circumstances, the cooling capacity of small and medium-sized chillers is usually expressed as “hp”, and the cooling capacity of large-scale chillers (such as large air-conditioning refrigeration units) is usually expressed as “cold ton (US cold ton)”.
