Healthcare Solutions

Health care facilities encompass a wide range of types, from small medical clinics to large, complex, and costly, teaching and research hospitals.
The challenge in the HVAC design of the healthcare facilities is not limited to comfort but also demands a type of control for contamination & pressurization for various types of areas in order to prevent cross infection.

Design Consideration

Infection Control
In a hospital environment, large amounts of harmful microorganisms tend to cluster. The most important rule of hospital design from an infection control point of view is not to expose the patient to harmful infections while in the hospital.
Airborne transmission occurs when either airborne droplet nuclei or dust particles disseminate infectious agents. In this case the control of ventilation and air handling is very needed to prevent nosocomial airborne transmission of microorganisms.

Energy consumption:
The amount of energy used up in healthcare buildings by traditional types of Heating, Ventilating and Air Conditioning systems is about 40% of the total building energy consumption. It also accounts for many harmful emissions released into the environment.

Noise Level:
Higher-than-recommended hospital noise levels may cause patients to lose sleep and impede their ability to heal, according to a new study in the Archives of Internal Medicine. The noise level should be restricted to 35 NC level for all patient rooms, operating rooms (major or minor), diagnostic rooms, audio suites, examination rooms, conference rooms, large offices, lobbies and waiting area.

Our Offering

  • Proper Design Services as per the international codes & standards to insure proper pressurization & ventilation for each part of the facility.
  • Accutrol Air Valves:
    • With a precise air flow reading, high accurate performance, Accutrol Air Valves can guarantee that all areas shall be ventilated & pressurized as per the design.
    • Low-Pressure Drop: Reducing the overall pressure drop in a ventilation system allows the system to be run at a lower static pressure. This requires less fan horsepower resulting in a significant reduction in energy cost, building’s environmental impact, carbon footprint and lowering noise levels in the duct, making the building environment more pleasant to work in.
    • Low-Noise Valve by design: The inspiration for the design of the AccuValve originated from analysis of the design of a silencer
    • Demand Static Pressure Reset Control functionality as per ASHRAE Standard 90.1 Without Additional Hardware.
  • MK Plastics Hazardous Extract Fans & K-KORE Energy Recovery Plenum:
    • High Efficiency Extract Fans requires lower horse power to achieve the building ventilation requirements. All MK Plastics are AMCA certified for performance & has the highest FEG (fan efficiency grade) in the market.
    • Revolutionary plenum solution for Energy Recovery Units that is fabricated from composite material, some of the features for the K-KORE plenums
    • Lightweight construction. Up to 40% weight savings vs. steel construction.
    • True no-thru-metal construction throughout the entire cabinet depth.
    • Unlimited salt-spray resistance
    • Highly Corrosion resistance.
    • Flame Spread index of less than 25 when tested according to UL 723.
  • Setra Room Pressure Monitors:
    • To ensure the integrity of the HVAC system that all areas are properly pressurized; high accuracy, industrial-grade pres.

Application

Following are various types of critical environment areas / applications

Isolation Rooms:

An isolation facility aims to control the airflow out of the room so that the number of airborne infectious particles is reduced to a level that ensures cross-infection of other people within a healthcare facility is highly unlikely. This may be achieved by:
  • Control of the Volume and quality of intake or exhaust air.
  • Maintain differential air pressures between adjacent areas.

A combination of Accutrol Tracking Pair Airflow control solution along with Setra pressure monitors achieves the following requirements in an isolation room:

  • Pressurization Control for both Main Room and Ante Room
    • Negative pressure in Airborne Infection Isolation “AII” Rooms
    • Positive Pressure in Protective Environment “PE” Rooms
  • Ventilation Rate (12 ACH As Per ASHARE-170)
  • Temperature Control
  • Humidity Control

Operating Theaters

Nowhere is infection control more critical than in operating rooms (ORs), where the surgical theatre exposes sensitive internal tissue to skin squames and airborne pathogens. From a ventilation standpoint, many types of rooms are treated as operating rooms, all of which receive positive pressure relationship to adjacent spaces. Rarely, highly infectious patients undergoing a surgical procedure will require a negative pressure OR.
A combination of Accutrol Tracking Pair Airflow control solution along with Setra pressure monitors achieves full airflow monitoring /control. The system can achieve the following requirements:
  • Positively Pressurization Controlled environment
  • Ventilation Rate (20 ACH As Per ASHARE-170)
  • Temperature Control
  • Humidity Control
  • Occupancy Control

Hospital Pharmacies/ Clean Rooms

Hospital pharmacies source many types of medications and treatments for patients, including Compounded Sterile Preparations (CSPs) for cancer treatment. Patients can become harmed by non-sterile and inaccurately prepared CSPs if improper ventilation compromises the environment surrounding personnel that prepare these drugs for use. This environment is regulated by the United States Pharmacopeia (USP) Chapter . USP requires a comprehensive environmental sampling (ES) program to identify trends, or points of failure, before they become critical. Hence, ventilation is a key component in controlling the spread of airborne particulates.
Accutrol Tracking Pair Airflow control solution along with Setra pressure monitors achieves full airflow monitoring /control. The system can achieve the following requirements:
  • Positively Pressurization Controlled environment
  • Temperature Control
  • Humidity Control
  • Bio-safety cabinet – air containment control & alarming
