Units
The use of units in this article makes me cringe. What kind of unit is a ton for cooling. If we are talking about an amount of cooled water, we still don't know in what time and from what starting temperature the water is cooled. — Preceding unsigned comment added by 46.126.154.230 (talk) 17:51, 14 November 2012 (UTC)

One ton of cooling used to refer to the cooling capacity of one ton of ice (per day, if I recall correctly). Now it has been standardized into 12,000 BTU per hour, and is commonly abbreviated "tr" as in 200tr. This lets HVAC/R personnel understand that it isn't referring to one ton of weight.

Also, what is the unit RT? It is not defined here. — Preceding unsigned comment added by 173.216.108.47 (talk) 00:23, 26 January 2014 (UTC)

It would be great if there was a section on the typical units used in the engineering of chiller plants. 170.121.14.11 (talk) 16:42, 14 November 2014 (UTC)Maddog

I've edited the units appropriately, adding a reference to the page that describes what a 'ton' is in refrigeration. Unfortunately, tons of refrigeration are completely different units then tonnes of mass, as the article seemed to indicate. Hopefully my edit will help add clarity in this regard. — Preceding unsigned comment added by 2605:A601:A2C:BC00:224:1DFF:FE23:DFC4 (talk) 05:07, 29 February 2016 (UTC)

How a chiller plant can produce chilled water by using heat energy. El método para evaluar los equipos de refrigeración, procede del tiempo en que se utilizaban bloques de hielo para eliminar el calor. Según pruebas científicas se necesitan 36.29 Kcal(kilocalorías) o 144 Btu (British Termal Unit) para fundir una libra de hielo a 0°C (32°F). Una tonelada de refrigeración (TR) es la cantidad de calor requerida para fundir una tonelada de hielo en un lapso de 24 horas. (1 tonelada americana es igual a 2000 libras). Si ocupamos 144 Btu de calor para fundir 1 libra de hielo, entonces, necesitamos 2000 veces más calor para fundir una tonelada de hielo (144 Btu/lb X 2000 lb = 288000 Btu (72576 Kcal). Este mismo procedimiento se aplica cuando se elimina calor de una sustancia (en los equipos de aire acondicionado y refrigeración, la sustancia es el refrigerante; por ejemplo: R22, R410a, R134a, etc.) Por lo tanto, si tenemos un acondicionador de aire que tenga una capacidad de 1 tonelada, eliminará 72576 Kcal/24h o 3023 kcal/h o 50.4 Kcal/min. Si tienes un chiller de 300 toneladas, multiplicas 300X72576 y el resultado es la capacidad de tu equipo para eliminar calor o refrigerar. — Preceding unsigned comment added by 201.132.24.205 (talk) 00:35, 16 May 2014 (UTC)

Shouldn't there be an article on the font of Chiller?DrWho42 17:00, 2 March 2006 (UTC)
 * What do you mean?

The chiller plant uses energy to run a compressor to compress a refrigerant that will condense back into a liquid and release its energy via a phase change. The liquid refrigerant than is evaporated at a different location to remove energy from the water lowering its temperature. The process continues and is the basic refrigeration cycle.

Refrigerants
There absolutely should be a reference for the data in this table. — Preceding unsigned comment added by 130.68.20.187 (talk) 19:50, 7 June 2011 (UTC)
 * Doesn't the refrigerant article have references, or is that bad policy? LightRobb (talk) 22:11, 18 April 2012 (UTC)

Chillers tend to be dominated by lower pressure refrigerants. This is because they have enough volume that building them to withstand higher PSI pressures rapidly increases the pressures exerted on the large surface areas, adding vastly to material cost. Yet, this section completely ignores refrigerants like R11 - which were (and still is!) a very prominent chiller refrigerant, yet includes refrigerants like R410A? Show me one single R410a chiller. This list needs to be updated with refrigerants that are relevant to chillers. — Preceding unsigned comment added by 2605:A601:A2C:BC00:224:1DFF:FE23:DFC4 (talk) 05:15, 29 February 2016 (UTC)

MOKON?
The link for MOKON is a product specific link, and it is more of an advertisement or press release than informational. I suggest that the link should be deleted, as I have worked in HVAC for years without having heard of it before. 170.121.14.11 (talk) 16:38, 14 November 2014 (UTC)Maddog
