How does the power of the main engine of the central air-conditioning water pump match the power of the inner coil, and is it the same as the refrigerant, that is, the refrigerating capacity of the inner engine is greater than that of the outer engine? According to the building structure, latitude, building orientation, room height and brand of fan coil unit, choose to use two rows of pipes or three rows of pipes. Cooling capacity calculation:

1 kcal/hour (kcal/hour) = 1. 163W, 1W = 0.8598 kcal/hour;

1USRT = =3.5 17kW, 1kW = 0.28434USRT.

1 = =2.5kW (air cooling unit), 1 = 3 kW (water cooling unit).

Second, the load index (estimated value) (for reference only)
