Chiller Cooling Capacity
Let look at how to calculate the cooling capacity. We’ll first look at how to calculate in metric units and then imperial. Metric units: The water flow rate of chilled water into the evaporator is 0.0995m3/s, the inlet temperature is 12*c and the outlet temperature is 6*c.

How to calculate electrical costs for cooling and power …

For putting together a business case costs and revenues are an important part of it. If you want to calculate the direct resource costs associate with hosting a server in your data center, you want to know the direct power consumption by the server in electrical costs and the costs associated with cooling the environment where the server is situated.
Server BTU Calculator
For these reasons we have developed these this server BTU and cooling calculator to help you plan and prepare proper cooling for your server rooms. Advanced Server Heat Load Calculator Use the heat load calculator below to estimate the electrical and cooling costs of up to 3 types of servers or devices and determine the estimated heat load that will be required to be handled by your ac unit.

How to Convert HVAC Tons to Amps

 · PDF 檔案How to Convert HVAC Tons to Amps In the heating, ventilation and air conditioning (HVAC) industry, tons are used as a way to measure an air conditioner’s cooling capacity. In particular, one HVAC ton is equivalent to 12,000 BTUs per hour. One BTU refers to the
Chiller – an overview
The energy savings attributed to switching from a single-chiller plant to a multichiller cooling plant depend on the load profile and climatic conditions. Table 8.5 shows the number of hours of operating one-chiller system at various part-load ratios for a load profile associated to office buildings located in four US climates.

Ton of refrigeration
A ton of refrigeration (TR or TOR), also called a refrigeration ton (RT), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment. It is defined as the rate of heat transfer that results in the freezing or melting of 1 short ton (2,000 lb; 907 kg) of pure ice at 0 C (32 F) in 24 hours.
