Central Heating and Cooling Plant
About CHACP I
History - CHACP I was constructed in 1967 and has since gone through two major expansions. The first was in 1974 when Boiler #3, Chiller #3 and cooling towers #3 & #4 were added to increase the capacity of the plant. The second was in 1999 when Chiller #4 was added as well as four additional Cooling Tower Cells to further increase the cooling capacity of the plant.
Chilled Water Capacity- The cooling capacity is tied to the amount of chilled water that can processed by the four steam turbine-powered centrifugal chillers. Currently that capacity is 20,000 tons.
Steam Capacity - Similarly to the cooling capacity of the plant, the heating capacity of the plant is tied to three 600 pounds per square inch, 750 degree, Natural Gas-Fired boilers. These three boilers produce up to 500,000 pounds of steam per hour.
Includes - CHACP I provides its services to 6.8 million square feet of the main campus through 7.75 miles of utility tunnels. Services include: 80psi steam for heating and humidification, circulates 7.5 million gallons of chilled water for cooling, and also provides a limited supply of compressed air and reverse osmosis water for select customers. The plant has a Back Pressure Turbine Generator Capable of Producing 935 Kilowatts of electricity for internal plant use, a 1,500 Kilowatt Emergency Generator to maintain plant equipment during power outages, and three water wells for cooling tower makeup.
Budget - CHACP I has an annual operating budget of $11,488,152 this includes all external utilities purchases such as electricity, natural gas and city water. The annual operating and maintenance budget is $1,884,705 which includes the operating and maintenance budget for the Texas Tech Museum and Fiber and Biopolymer Research Institute Utility Plants. CHACP I has an annual capital improvement budget of $900,000.
