40HP 110kw Air Cooled Chiller With R134a

1.How does a chiller system work?

Chiller has two circulation,one is process water circulation,the other is refrigerant gas circulation.Heat picked up from the process.Heat transfers to refrigerant circulation.Heat is remove to air or water.

2.How to calculate cooling capacity for chillers?

Cooling Capacity(kw)= Flow Rate(m3/h)*Temp Change(T1-t2)/0.86

Heat Load= C(specific heat)* M(quality output per hour )*Temp Change(T1-T2)

3.Types of chiller system?

Air Cooled Chiller and Water Cooled Chiller.Water cooled chiller needs a separated cooling tower and has a higher efficiency,but less easier than air cooled.

4.Cooling capacity unit conversion?

1 kcal/h = 1.163W,1 W = 0.8598 kcal/h; 

1 Btu/h = 0.2931W,1 W = 3.412 Btu/h; 

1 USRT = 3.517 kW,1 kW = 0.28434 USRT;  

1 kcal/h = 3.968 Btu/h,1 Btu/h = 0.252 kcal/h; 

1 USRT = 3024 kcal/h,10000 kcal/h = 3.3069 USRT; 

5.The chiller can heat?

Yes,by the electrical heating wire.Please kindly inform us the hot water temp or heating capacity.

6.Chiller maintenance?

Step 1: Keep Tubes Clean

Step 2: Ensure a Leak-free Unit

Step 3: Sustain Proper Water Treatment(prevent scale, corrosion)

Step 4: Analyze Oil and Refrigerant
