Cooling System Cove.tool Help Center

Chillers utilize a refrigeration cycle to chill water for distribution around a building and reject heat to another medium. A water cooled chiller rejects heat from a building via a condenser water system and a Cooling Tower. The primary energy source for a water cooled chiller in cove.tool is electricity and electricity is also used by the ...

Jul 26, 2019 Recently we worked on a 130,000 ft 2 medical office building located in Salt Lake City, UT where an IDEC system can provide low-cost cooling up to 3,460 hours per year. This amounts to about 80% of the cooling load for the building in a typical year, saving tens of thousands of dollars per year in operating costs.

Difference Between DX Cooling Units and Chillers

Difference Between DX Cooling Units and Chillers

Jun 28, 2016 The DX Air Conditioner system uses a refrigerant vapor expansion and compression cycle to cool air coming in through a supply plenum and returns it to the area that needs cooling through the return. The unit effectively circulates refrigerant through a series of condensers and evaporators, which warm air moves through and is cooled down before being …

How do absorption chillers work?

How do absorption chillers work?

Michael Faraday came up with the idea of the absorption chiller based on this concept in 1824. The principle behind an absorption process is to separate and recombine to fluids (refrigerant and absorbent) to create a cooling effect. Usually, absorption chillers are either NH 3 -H 2 0 (ammonia-water) cycle or LiBr (Lithium bromide) cycle.

The diagram above shows a cooling cycle of a heat pump DX system. The valve used is a reversing valve that reverses the refrigerant flow to enable the heat pump to run cooling or heating. A normal valve is used when a cooling only system is needed. This type of system is also known as the vapor compression systems.

4. HVAC AND REFRIGERATION SYSTEM

Using a phase-change refrigerant, the chiller’s compressor pumps heat from the chilled water to the condenser water. – Condenser water loop. Water absorbs heat from the chiller’s condenser, and the con-denser water pump sends it to the cooling tower. – Cooling tower loop.The cooling tower’s fan drives air across an open flow of the hot
