HVAC and VRF, Rocky Hill CT | Surgery and Medical Center

Controlled Air Inc. — Thu, 09 Aug 2018 14:57:03 +0000

Controlled Air, Inc. was excited to work with AZ Corporation on the newest orthopedic surgery center in Rocky Hill, Connecticut with 7 operating rooms and 1 procedure room. This was a new build project that required strict standards to adhere to the ASHRAE requirements for any medical center, such as increased air change outs and HEPA filtration. The project has three phases: Phase 1, The Core; Phase 2, Surgery; and Phase 3, Medical Office Building.

Just to give you an idea of the enormity of this project, it required over 58,000 ft. of ductwork with a combination of insulted and non-insulated. A brief overview of just some of the HVAC equipment we installed includes:

Seven AAON units with humidity control, return air bypass, energy efficient dehumidification and economizers; one AAON units with a premium efficiency motor, economizer with power exhaust and a VFD; one AAON unit with an Energy Recovery wheel, premium efficiency motor, and 2 motors on 2 VFDs; and two 25 Ton High Efficiency Lennox RTUs with variable volume air flow and economizers. All new RTU’s installed use R-410A refrigerant per the EPA requirements.
We also installed six (6) Sterling Linear Radiant Hydronic Ceiling Panels. Radiant Panel ceiling systems are an energy and cost saving method of heating. They provide distributed heating radiantly rather than by forced air providing a “draftless” environment.
2 PK Gas fired condensing boilers with Axiom Condensate Neutralization Tank and Nuro touch-screen control system.
8 Nortec Humidifiers, The industry’s most precise humidifier. An isothermal system that produces mineral free, odorless, sterile steam from any water type.
Ceiling Grid System by Titus which allows for the building of critical environment spaces with flexibility. Each system is custom engineered to meet the requirements of codes and guidelines, such as ASHRAE Standard 170 and the Facility Guidelines Institute (FGI) ‘Guidelines for Design and construction of Hospitals and Outpatient Facilities.’

The Expected completion date is 10/31/2018.

What is always challenging about medical facilities and pharmacies, are the extensive regulations for air changes, filtration, as well as humidity and temperature controls. Unlike office buildings where the building requires consistent settings throughout the building, medical facilities can have different requirements per area. Surgical rooms and pharmacies, have different settings from the offices and also from each other. It take extensive controls and programming to make sure each area functions as required.

HVAC Installation, Hartford CT | Hartford Hospital Histology

Controlled Air Inc. — Thu, 24 May 2018 13:38:49 +0000

For this project we needed to set up a new lab in an existing hospital space. There was a lot of intricacy, coordination and planning to work inside a functioning hospital that allowed for no downtime. The exhaust fan was 3 floors down and autopsy and tissue sampling was using the same system. Additionally the air handler had to be changed on the fly as it fed the maternity ward and other areas that could not be shut down.

We furnished and installed one roof mounted exhaust fan connecting to existing system, along with a new steam coil, hot water coils, piping modifications, and custom grilles for the downdraft system cabinets. Additionally we installed three Accu Valve VAV boxes, two with fume hood controllers, registers, grilles & diffusers and piping as required. New stainless ductwork with exterior supply duct having board insulation with peel-n-seal covering. We also installed a specialty exhaust system on the lab tables that pulls the air through the back splash to reduce or eliminate issues of contamination or smells.

Building Controls, New Haven CT | Pharmaceutical Laboratory

Controlled Air Inc. — Thu, 07 Dec 2017 18:04:59 +0000

Controlled Air, Inc. installed a Building Control System (BMS) for a pharmaceutical laboratory and office building allowing for proper operation and sequencing. The BMS was integrated with installed mechanical and process equipment. The BMS monitors the electric and BTU usage and work to make equipment operate at peak efficiency. The BMS is made by Johnson Controls by their Facility Explorer line that allows for remote monitoring and alarming if any issues arise. What makes this system more complex than most is the use of data sharing between all systems to make sure all equipment runs optimally. There are spaces within the building that require critical temperature and humidity controls in order to operations to run smoothly.

Below is a list of some of the equipment the BMS also monitors and controls:

Steam boilers for the lab and domestic hot water.
Life safety and tenant generator systems supply back up power in the event of power failure for critical areas.
Kitchen exhaust fans for occupancy, allowing the fans and exhaust hoods only to run when the space is occupied and in use.
Cooling tower controls, which provides temperature controlled water to the chillers, and heat exchangers serving individual floor air conditioning units.
Refrigerant monitoring to control exhaust in case of a leak.
Individual floor air conditioning units, while also controlling occupancy. The individual units serve VAV’s throughout all floors, to maintain individual space temperatures.
Stairwell pressurization fan control in the case of a fire.
Boilers serving the entire buildings heating requirements, including baseboard heat, air handling heating coils and zone reheats throughout the space.
