Heating, ventilation, and air conditioning (HVAC) is a primary mechanical engineering service provided by Bath Group, Inc.
Bath engineers are experienced and trained in the principles of thermodynamics, fluid mechanics and heat transfer for indoor environmental comfort and process chilling. In addition to designing for environmental comfort, they consider pressurization to protect against contamination, humidity control of process areas, and energy consumption.
Our engineers are experienced in HVAC design for new facilities and analyzing existing facilities for issues and HVAC efficiency. New designs are based on the facility construction, size, and number of rooms, room uses, local climate, utility costs, HVAC space requirements and which type system is best for client needs. Automated control systems are designed based on facility size, number of rooms, need for occupant sensors, and need for multiple regions for heating and cooling, and scheduling. These will determine if simple programmable thermostats are used or if Direct Digital Control (DDC) systems are needed
Our engineers and technicians utilize specialized tools and instruments to measure performance of exhaust hoods, exfiltration, humidity and air flow. Sophisticated computer programs are used to model existing conditions and digitally test proposed solutions.
To determine HVAC efficiency Bath engineers look at the efficiency specs of the HVAC components, appropriate size for facility, local climate, usage, and types of fuel used. The engineer looks at the systems’ Seasonal Energy Efficiency Ratio (SEER), the Annual Fuel Utilization Efficiency (AFUE), the Heating Seasonal Performance Factor (HSPF) and the Wattage the system uses to estimate the systems expected consumption of energy.
