What does a Trane chiller do?

Our chillers serve HVAC systems that deliver the right temperature, humidity and ventilation for the space, but they also help minimize operating costs with superior energy efficiency levels, low sound levels and with minimal environmental impact.

What are centrifugal chillers used for?

A centrifugal chiller uses the vapor compression cycle to chill water. It throws off the heat collected from the chilled water plus the heat from the compressor to a water loop. The water loop is cooled by a cooling tower. Centrifugal chillers are popular because they have relatively few moving parts.

What are the advantages and disadvantages of water-cooled chillers over air cooled chillers?

Water-cooled chillers usually don’t need replacement as often as air-cooled chillers do. They aren’t exposed to outdoor elements such as rain, snow, ice, and heat, which makes them less vulnerable. While air-cooled chillers have ducts and vents that create noise, water-cooled chillers operate quietly.

What is the best chiller efficiency?

Maximum efficiency occurs with most chillers running at approximately 70-75 percent load and the lowest entering condenser water temperature (ECWT), based on design.

How do I know what tonnage my Trane chiller is?

The easiest way to look Trane tonnage model number is on the AC unit itself. Go to the condensing unit on the outside and look for the data plate stamped on the actual side of the compressor. Find the model number. Within this string of letters and numerals, you should find an even, two-digit number.

Why do we need chillers?

Chillers generate chilled water which is used to provide air conditioning in buildings. All building generate a lot of unwanted heat, whether is be solar heat gain from the sun beating down on it or from the occupants inside and the equipment they use.

Are chillers efficient?

In general, centrifugal chillers with variable speed drives can typically see a 10 percent to 13 percent efficiency gain for every 5 degrees of condenser water temperature relief. Constant speed chillers also benefit, but only about 5 percent efficiency gain for every 5 degrees of chilled water relief.

What is a good COP for chiller?

The electrical power demand of the chiller to produce this is 460kW. The metric calculation would be: 2,500kW / 460kW = 5.4 so the COP is 5.4. This means that for every 1kW of electricity you put into the machine, you will produce 5.4kW of cooling.

Is a Trane XR14 good?

We’ve identified the Trane XR14 as our best value air conditioner because of its high efficiency ratings and more affordable price point. With a SEER rating of up to 16, you can expect to see noticeable energy savings when you replace an older, less efficient unit.

What are the characteristics of A Trane chiller?

Compressor Speed Operating Pressure Low Low Med/High High Delivering lowest acoustic and vibration characteristics First charge is your last charge (efficiency) Hermetic Direct Drive Open Gear Multi Drive Hermetic Gear Drive

What kind of refrigerant does Trane CenTraVac chiller use?

Trane CenTraVac® chillers feature a time-tested and proven low-pressure design utilizing environmentally friendly refrigerants R-514A and R-1233zd. They provide the safety of low pressure with continued product enhancements in a leak-tight design.

How does a centrifugal water chiller work?

Many of the components of the centrifugal water chiller are similar to those of other chiller types. This particular centrifugal water chiller makes use of a shell-and-tube evaporator where refrigerant absorbs heat from the water flowing through the tubes. The compressor is made up of 1 or more centrifugal impellers.
