Heating, Ventilation, and Air Conditioning (HVAC)

The UMC established minimum requirements and standards for the protection of the public health, safety and welfare. 101.3 Scope. The provisions of this code shall apply to the addition to or erection, installation, alteration, repair, relocation, replacement, use, or maintenance of heating, ventilating, cooling, refrigeration systems; incinerators; or other miscellaneous heat-producing appliances within this jurisdiction.

The document discusses VLA, VRLA, and Nickel Cadmium stationary battery installations and is intended to serve as a bridge between the electrical designer and the heating, ventilation, and air-conditioning (HVAC) designer. Ventilation of stationary battery installations is critical to maximize battery life while minimizing the hazards associated with hydrogen production. This guide describes battery operating modes and the hazards associated with each. It provides the HVAC designer with the information to provide a cost-effective ventilation solution.

This data sheet covers electrical protection and fire protection for cables and bus bars and discusses aluminum conductors, describing methods of connecting, splicing and terminating to prevent excessive heating that could result in arcing and fire.

The purpose of this standard is to develop industry-wide requirements including methods and procedures for the control of battery room and enclosure environments. This includes adequate ventilation of battery-generated gases, the dissipation of battery-generated head, the control of room and enclosure temperature, the management of battery electrolyte spills, and in general the control of any contaminates within the battery room or enclosure.

The USEHC established minimum requirements and standards for the protection of public health, safety and welfare for application to the erection, installation, alteration, repair, relocation, replacement, addition to, use or maintenance of solar energy systems, including but not limited to equipment and appliances intended to utilize solar energy for space heating or cooling; water heating; swimming pool heating or process heating; and solar PV systems. The code includes systems where equipment and components collect, convey, store and convert the sun’s energy for a purpose, including but not limited to service water, pool water and space heating and cooling as well as electrical service.

This standard provides technical requirements for exhaust systems that will protect lives and property from fires and explosions and minimize damage in the event that such fires and explosions occur.

1.1
This Standard applies to newly produced gas-fired low-pressure steam and hot water boilers with gas inlet pressure ratings not exceeding 0.5 psi (3.5 kPa) and having input ratings of less than 12,500,000 Btu/hr (3 663 389 W) (see Clause 3, Definitions), hereinafter referred to as boilers*, constructed entirely of new unused parts and materials, for operation at or below the following pressures and temperatures:
Steam heating boilers 
   15 psi (103.42 kPa) steam pressure 
Hot water heating boilers 

This Part of this European Standard applies to all water-tube boilers as defined in EN 12952-1 which are heated by combustion of one or more fuels or by hot gases for the generation of steam and/or hot water.
This Part of this European Standard applies to those components between the feedwater inlet and the steam outlet of the steam generator. The quality of the steam produced is outside the scope of this standard.
