Since its inception, MDW has seen growth in air travel. To handle the increased passenger volume and modernize the airport, a larger terminal went under construction in 2000 and was completed in 2004 as part of a terminal development program. The program also included a new Central Heating and Refrigeration Plant (CHRP), which was completed in 2000 to serve the increased cooling and heating needs of the new terminals. The CHRP was a separate contract from the terminal modernizations and was awarded using a third-party design build contract. Unicom Thermal Technologies (UTT) was awarded the project with Hill Mechanical Group (HMG) as its contractor. 

There are six basic types of cooling systems that you can choose from to meet the cooling needs of your load. Each one has its strengths and weaknesses. This article was written to identify the different types of cooling systems and identify their strengths and weaknesses so that you can make an informed choice based on your needs.
Temperature control of the musts during the fermentation process is required for the production of high quality wines. Alcoholic fermentation is the chemical reaction in which yeast is used to transform the natural sugars of the fruit into alcohol. The heat generated by this exothermic reaction has to be managed. If must temperatures are allowed to reach the 85°F to 105°F range the reaction will be stopped. This results in high sugar content and an unstable product that requires the addition of sulphur dioxide (SO2) to allow it to be stored without spoiling. In general, optimal fermentation temperatures are 65°F - 68°F for white wines and 77°F for red wines.
Industrial plants are major consumers of water. Water is used in many processes. Sustainability projects focus on reducing the consumption of water and the energy-costs associated with cooling water so it may be effectively used.
It is widely recognized that compressed air systems account for ten percent of all electricity and roughly sixteen percent of U.S. industrial motor system energy use. Seventy percent of all manufacturing facilities in the United States use compressed air to drive a variety of process equipment.
