Water Cooled Chiller System Explained

R427a pressure enthalpy chart.

Water cooled chiller system explained. Evaluating overall chiller plant performance will therefore involve an analysis of total power consumption of the compressor pumps cooling tower fans etc. Chilled water system basics. The condenser is located between the compressor and the expansion valve. The majority of the time it s usually something to do with the cooling tower or the flow of condenser water between the chiller and the cooling tower.

Chilled water system basics chilled water systems in residential hvac systems are extremely rare. Boiler system explained lthw paul evans jun 5 2019 1. If a partial blockage occurs in this condenser return line then the flow rate is going to change. Condensers for water cooled chillers.

Water cooled chillers have greater complexity due to the connection to a cooling tower system. This is a pretty advanced chiller video so if you re new to the topic then i highly recommend you start from the basics first. Chillers have many uses from bringing the temperature down in an ice hockey rink to cooling large buildings where low temperatures are essential such as food processing plants and petrochemical factories. In this article we are going to be taking a very detailed look at the design data for a centrifugal water cooled chiller.

While assessing the quality of a chilled water system machine efficiency is a major. In this article we are going to be looking at the condenser of a chiller. Water cooled chillers have a sealed condenser and water is pumped through to take the heat away and disperse this through the cooling tower. Chilled water systems provide cooling to a building by using chilled water to absorb heat from the building s spaces.

At the heart of the water chilled system a chiller removes heat from water by means of a refrigeration cycle. Water cooled chiller has advantages over air cooled chiller in terms of capacity efficiency life and environmental impact. Water cooled chiller design data. Water cooled chiller is a device used to remove heat and transfer it to the environment.

How chilled water systems work. A typical chiller uses the process of refrigeration to chill water in a chiller barrel. Water cooled chillers are mostly used in air conditioning industry or any other specific places that require temperature control. Chiller designs differ depending on the building or industry they are installed in and the temperatures required.

The cooling tower will also use a fan to reject the heat. Hot high pressure refrigerant vapour enters the condenser and liquid refrigerant exits the condenser. To evaluate comprehensive efficiency measures such as kw ton. In this case we find water cooled chillers to have notably longer lives in comparison to air cooled chillers.
