Cooling Water System Chiller Upgrades

HYDAC Chiller.

The team measured and adjusted all airhandling chilledwater flow for optimum performance and installed VFDs on ballroom airhandling units equipped with carbondioxide sensors to produce healthy indoor air quality IAQ.

The team removed 15000 pounds of chlorofluorocarbon CFC R500 and replaced it with 15000 pounds of nonozonedepleting hydrochlorofluorocarbon HCFC R134aSome capacity loss occurred due to the conversion but the refrigerant is more efficient Plutz says.

A typical watercooled chilled water system consists of 4 major components as below ChillerEach component has a lot more to talk about but in this post Ill give you an overview of them and explain through the chilled water system as a whole.

An industrial chiller is a cooling system that removes heat from one element water and transfers it into another ambient air or waterThe chiller will provide a stable temperature flow and pressure once it has been programmed by a user for their individual needs.

BAS was recently involved in the energy analysis design and install of a chilled water plant system replacement including upgrades to the corresponding digital control systemThe project was awarded a 171000 rebate and is estimated to save over 84000 in annual electric and gas savings with an 11 return on investmentThe project is estimated to conserve 395100 kWh and 19900 therms annually.

Energy Savings for Optimized Chiller Plant after HVAC Upgrades.

Most lasers include a basic external water pump for cooling the laserWith this configuration you place the pump in a bucket of water with ice packs to keep your laser coolThe problem with this is you dont know what the temperature is and you have to constantly replace the ice packsLaser tube life is shortened by excessive heat.

COOLER WATER SYSTEM CHILLER UPGRADE City of San Diego MBC Cooling Water System Chiller Upgrade replaed the entire chilled water system wth 3 new 250ton chiller units including primary and secondary pumps.

Feb 15 2022nbsp018332A properly sized watercooled chiller system is an asset to every industrial operator looking to maximize productivity while minimizing equipment downtimesThe key advantages of using a water chiller system for process cooling are outlined belowWater chillerenabled process cooling is a very efficient method for various.

Installing a new energyefficient unit with a cooling energy efficiency rating of 13 would result in cooling mode electricity costs of about 36900 annually—a savings of 16400 per yearIf the heating component of the system was improved to 90 percent efficiency the heating savings would be 2000 per year.

May 03 2018nbsp0183326In this article we’re going to be discussing different ways to improve the efficiency of your existing chiller setupWe’re going to cover Compressor Retrofit Compressor VFD Chilled Water Reset Condenser water reset Condenser and Evaporator cleaning Expansion Valve Air cooled chiller condenser fans Free cooling or Economiser.

May 04 2020nbsp018332Learn about chillers hvac upgrades replacements and related trends for building operations successThe chiller can be shut down and free cooling would be provided by circulating condenser water through one side of the heat exchanger and chilled water through the other side.

Part two of this increases each chiller by approximately 20 1Watercooled chillers will now have a full load efficiency of 033 Integrated Part Load Value IPLV 2Aircooled chillers will now have a full load efficiency of 11.

Sep 22 2020nbsp018332Summary of the Adiabatic Cooling ProcessAdiabatic cooling of air is an indirect evaporative cooling process air flowing through a closedloop is precooled to the desired temperatureWater channeled through an adiabatic system is evaporated as requiredThe state change from liquid to gas results in an energy transfer in the form of heat.

TechCom was contracted by the City of San Diego for an MBC Cooling Water System Chiller UpgradeThis project replaced the entire chilled water system with three new 250ton chiller units including primary pumps and secondary pumps with Variable Frequency Drives  TechCom completed the project on time and under budgetThe new energy efficient chillers and pumps will save the City millions of dollars in energy costs over the next 20 years.

The CoolSense174 prepackaged HVAC design system combines a dedicated outdoorair system DOAS with chilledwater sensiblecooling terminal units to deliver a flexible energyefficient solution that enhances comfortable spaces and simplifies maintenanceMaximizes comfort through zonespecific temperature adjustments independent from humidity.

The facility is a 3floor 80000 ft² building that was constructed in 1989The primary use of the facility is as office space for tenantsThe building is approximately 60 core spaces and as a result requires cooling year round.

The other is used along with the 500 ton chiller to supply 40176F chilled water to meet the cooling and dehumidification loads for the buildingThe chilled water plant also includes three open loop cooling towers each sized to match the three chillers with a common sump.

The proposed chilled water heat exchanger system would allow the cooling tower to provide free cooling when ambient conditions allowThe heat exchanger would have two 3 horsepower pumps that operate constantly during freecooling operationThe free cooling system would eliminate yearround chiller operation previously required to keep core spaces comfortable.

The total cost of the chiller plant upgrades was 641000This investment resulted in an annual cost savings of 110000 an annual energy savings of 104 percent with an internal rate of return of 16Mobil purchased the chillers before the tuneup and conversion of the return air system for lab spaces.

This project also includes the replacement of all the concrete slab and pads within existing chiller area to accommodate the new equipment and all necessary piping mechanical electrical instrumentation and controls as required by the cooling water system chillers upgrades.

Under the proposal all HVAC equipment in the building would be controlled via JCI FX controls allowing for proper equipment scheduling load resets temperature setbacks alarming remote monitoring and a better user interface for operatorsAll pneumatic controls were to be removed from the building.
