Specifications include, but are not limited to: LUBBOCK COUNTY COURT HOUSE: The closed loop water system consists of two systems: 1. Chilled Water (chilled water comes from central plant chiller) 2- Chilled Water Pumps 2- Interconnected Chilled Water Pumps 2. Heating Water 2- Heating Water Pumps 3- 2mBTU Hot Water Boilers The chilled water system consists of the chiller loop which is supplied by the chiller pump(s). The chiller piping loop supplies chilled water to the building chilled water loop piping system, and pumped to the building HVAC. The chilled loop piping is interconnected to the Central Plant system by the tunnel piping and is isolated/controlled by the BAS (Building Automation System) to open/close the interconnect valves as required. CENTRAL PLANT: The closed loop water system consists of two systems: 1. Chilled Water 1- 350 ton York Chiller 1- 350 ton Cooling Tower (BAC) 1- 50 ton ClimaCool Modular Chiller 1- Chiller Pump for ClimaCool Modular Chiller 1- Heat Exchanger for ClimaCool Modular Chiller 2- Chiller Pumps for York Chiller 2- Tower Pumps for York Chiller 2- Chill Water Building Pump for the Law Enforcement Center The Chilled Water System consists of the chilled water loop which is supplied by make-up in the Central Plant. The chilled water loop pumps are fed from the chiller loop. The building chilled water pumps supply chilled water to the Law Enforcement Center HVAC units. The chiller loop piping system is interconnected to the Lubbock County Courthouse system by the tunnel piping and is isolated/controlled by the BAS (Building Automation System) to open/close the interconnect valves as required. The Modular chiller, Modular chiller pump and Heat Exchanger is connected to the Chilled Water Systems, and used as a backup chiller if ever the emergency power is used, or the Central Plant’s main York chiller goes down. 2. Heating Water System 3- 2mBTU Hot Water Boilers 2- Heating Water Pumps for the Law Enforcement Center 2- 7.5 cu. ft. Water Softener The Heating Water System is operated by the BAS (Building Automated System). Operation of heating water system is usually year round to support the building’s Variable Air Volume (VAV) box’s reheat coil and/or Multi-Zone Air Handler Unit’s temperature requirements. The system has a regulated make-up system from domestic water. ADULT PROBATION: 1. Chilled Water: 1- 40-ton chiller (Air Cooled) 1- Chilled Water Pump 2. Heating Water: 2- 2 mBTU Hot Water Boiler 1- Heating Water Pump System has a regulated water make-up system from domestic water. Both systems are controlled and regulated by the BAS (Building Automated System). 916 MAIN STREET BUILDING: 1. Chilled Water 1- 311 ton Trane Chiller 1- Tower Pump for Chiller 2- Chiller Pumps for Chiller 2- Building Pumps for the Chilled Water Loop 2- Plate and Frame Heat Exchangers The chilled water system consists of a chiller loop piping system which supplies chilled water to the building chilled water loop pumps and also supplies chilled water to the one of the Plate and Frame Heat Exchangers. 2. Heating Water System: 3- 2 mBTU Hot Water Boilers 2- Heating Water Building Pumps 3- Recirculating pumps for the hot water boilers The Heating Water System consists of 3- 2mBTU Hot Water Boilers with a recirculating pump for each Boiler. This Hot Water Loop supplies heating water to the building Heating Water Pumps. This is a 4-pipe system that is controlled by the BAS (Building Automated System). LUBBOCK COUNTY DETENTION CENTER: 1. Chilled Water: 2- 400 ton air-cooled Trane Chillers 2- Chiller Pumps 2. Heating Water: 7- 2mBTU Hot water Boilers 2- 1.3mBTU Hot water Boilers 2- 1.7mBTU Hot water Boilers 2- Heat Exchangers 3- Heating Water Building Pumps 11- Recirculating pumps There are 7 Hot Water Boilers, 2 building pumps, and 7 boiler recirculating pumps that support the HVAC’s heating water loop. The other 4 Hot Water Boilers and 4 boiler recirculating pumps provide heated water to the 2 Heat Exchangers, which heat the domestic hot water loops.
