Recommendations to HVAC Engineers
As HVAC system engineer, one has to keep an eye on all factors and areas that can decrease the efficiency of system or increase downtime or HVAC system unavailability or increase the maintenance cost…
HVAC Valves
HVAC Valves are such components without which we cannot control flow in pipes .Valves are needed for every media whether it is water, gas, air or any other liquid. Valves would have…
HVAC Water Chillers Principle
Water chillers are backbone of HVAC cooling systems.Water chiller is a refrigeration machine which produces chilled water ( Approx 7 Degree C ~ 12 Degree C). The primary function of a chiller is to…
What is an Absorption Chiller? – Working Principle
Here learn the concept of an absorption chiller. HVAC chiller works in the concept of vapor absorption technology.
HVAC Double Effect Absorption Chiller
Undesrtanding the basics of Double Effect Absorption Chiller Double effect absorption chiller is an improvement in single effect lithium bromide chiller. Double effect water chillers have more coefficient of performance and enhanced…
Capacity Control of Absorption Chillers
Capacity of absorption chillers needs to be adjusted with respect to load on HVAC water chillers. Capacity control of HVAC chillers is very logical and required to save the input energy at low or part-load…
Difference between HVAC Absorption Chillers and Electric Chillers
In this post, we will learn the difference between an absorption chiller and an electric chiller used in HVAC systems.
Difference between Water Cooled Chiller and Air Cooled Chiller
In this post, we will learn the difference between water cooled and air cooled chillers in an HVAC system.
