Landscape orientation is recommended for that page. Beverages may accompany the tray or may be placed on the tray at a nourishment kitchen at the nursing unit. Heat release information is often available from equipment manufacturers, and information on the frequency of usage may come from the eventual equipment user.

This difference in pressure between the room and the adjacent architectural space s is accomplished under most codes by providing differentials in clnics flow rates VFR of supply, return, and exhaust air and door s closure.

Central Sterile Services which may serve Obstetrics and Emergency as well is a closely related function.

HVAC Design Manual for Hospitals and Clinics

The operation of an Emergency Department follows a fairly standard pattern. Invasive and minimally invasive procedures are performed in operating rooms. The maintenance function in health care facilities can be provided in many different ways; some owners use in-house staff for sophisticated and sensitive maintenance services, whereas other owners perform a minimum of work in house and contract out all other needed services.

This term may also apply to any microscopic agent that is a respiratory irritant and includes allergens and toxigenic fungi. The Director of Engineering may also have collateral duties including safety and security.

Transmission of infection to the patient from the environment is usually not a problem. This chapter introduces and summarizes HVAC design considerations and methodologies that are particularly significant in designing systems for hospitals. Load Calculations and Equipment Heat Gains This appendix is not intended to duplicate any of the chapters in the ASHRAE Handbook—Fundamentals on air-conditioning load calculations but rather to highlight the specific aspects of cooling and heating load calculations for health care facilities.

Perforation of the esophagus is possible, particularly if esophageal stricture or cancer is present.


The risk of infection is not limited to patients. The Tissue Typing Laboratory performs tests required for bone marrow and solid organ transplantation. Contagious diseases not considered dangerous to the general public, such as measles and chicken pox, pose grave health risk to the foor of pregnant mothers who may acquire the infection through, for example, exposure to other patients in a waiting room.

The HVAC design must ensure that the required? We hope that the Design Manual will be adopted widely and used as a tool for education.

New ASHRAE reference guides hospital HVAC design – Environmental Services

Standard is often cited as a minimum standard for determining outside air quantity for individual spaces and in addition provides guidance for calculating minimum outside air rates for central systems. Examples of process cooling include modular cooling units MCUlinear accelerators, magnetic resonance imaging, PET Positron Emission Tomographic scanners, data centers, and refrigeration condensers.

Some examples of air-cleaning devices are filters in air-handling units or ducts and fixed or freestanding portable devices that remove airborne contaminants by recirculating air through a HEPA filter.

In the case of serious trauma or medical condition, the patient may be transported to the Surgical Department. Definition of surgical microbiologic clean air. If the outpatient surgical facility is part of an acute care hospital or other medical facility, services may be shared to minimize special requirements. For nursing units, the medication is separated fod doses and administered by staff according to the order of the prescribing physician. There are special considerations for the design of operating rooms.

The condition of the patient is assessed by a triage fot in some departments and by a less formal method in others. Emergency power EP is mandated by several codes and standards for HVAC equipment considered essential for safety and health. Where clinice higher outdoor air requirement is called for in Standard 62 than ashre Tablethe higher value should be used. Viruses, bacteria, fungi, and asbestos are examples of respiratory pathogens.

Health care facilities are environments of controlled hazards. It also covers alternative cooling plant and heat rejection methods and the integration of thermal storage systems. Larger institutions may have an umbrella organization under which there are subsidiary for-profit or not-for-profit components.

Designers should also become aware of the heat release and environmental conditioning requirements for electronic communications and data equipment spaces that support various medical functions. Hospitals, skilled nursing facilities, and outpatient surgical centers ambulatory surgical centers are the primary types of facilities addressed in this book. These areas are for normal, uncomplicated births.


Directors or managers for marketing and planning, medical staff relations, and public relations may also report to the senior executive. Following is a partial list of specialty units: The annual operating costs of HVAC systems, including both energy consumption and maintenance materials and manpower, constitute a significant portion of overall building costs.

Knowledge of, and insight into, these criteria are needed to develop a design that will satisfy the owner and operators of the facility.

Positive pressurization produces a net flow of room air out amd a space toward the reference space through any opening between the two spaces. Maintenance shops, such as woodworking, painting, and welding, may have environmental control problems as serious as those of medical operations spaces.

Material from the AIA Guidelines is used with permission. A treatment clinic is a facility that provides, on an outpatient basis, major or minor treatment for patients that would render them incapable of taking action for self-preservation under emergency conditions without assistance desigm others.

Such rooms are positively pressurized to protect climics patient. Pressurization is important for infection control. These criteria should be used when not superseded by criteria from the owner or local jurisdiction.

Further unpacking may occur, and some items may be placed in a storage section designed for unit-of-issue fulfilling. This facility is a new and emerging form of outpatient center that can provide a wide array of outpatient diagnostic services and minimally invasive procedures.

Heating hvc steam generation equipment: Upper Gastrointestinal Tract Endoscopy: As a rule, environmental control requirements and the relative role of the HVAC system in life safety and infection control become more important with increasing complexity of the medical services provided and the degree of illness of the patient population.
