M-Tech provides OEM HVAC controls and accessories. HVAC (heating, ventilation, and air conditioning) is the technology of indoor environmental comfort. Equipment that is used for (HVAC) has been in high demand. This equipment goes a long way in providing a workable infrastructure to small and medium enterprises pertaining to commercial building as well as for residential and commercial buildings. No matter where you are in the world, your building requires heating, ventilation, or air conditioning to provide a comfortable productive environment for your occupants. However, HVAC isn't cheap, it accounts for approximately half of a typical building's total energy consumption. Making sure your system is running as efficiently as possible is critical to your building's operational costs.
Heating: Heaters (H in HVAC) are appliances whose purpose is to generate heat for a building. This can be done via central heating. Such a system contains a boiler, furnace, or heat pump to heat water, steam, or air in a central location such as a furnace room in a home, or a mechanical room in a large building. The heat can be transferred by convection, conduction, or radiation.
Heating devices, or systems:
- Cathode heater, a coil or filament used to heat the cathode in a vacuum tube or cathode ray tube
- Central heating, method of providing warmth from one point to multiple rooms or apartments of a building
- Convector heater, a heater which operates by air convection currents circulating through the body of the appliance
- Dielectric heating, the phenomenon in which radio wave or microwave electromagnetic radiation heats a dielectric material
- District heating, a system for distributing heat generated in a centralized location for residential and commercial heating requirements
- Fan heater, a heater that works by using a fan to pass air over a heating element
- Feedwater heater, a power plant component used to pre-heat water delivered to the boiler
- Gas heater, a heater that burns natural gas or liquefied petroleum gas
- Geothermal heat pump, a heat pump that uses the thermal mass of the Earth to regulate indoor temperatures
- Hydronics, the use of water as the heat-transfer medium in heating and cooling systems
- Induction heating, the process of heating a metal object by electromagnetic induction
- Radiant heating, a heating system which heats a building through radiant heat rather than convection or forced-air heating
- Radiator, a heat exchanger designed to transfer thermal energy from one medium to another for the purpose of cooling and heating
- Solar furnace a structure used to harness the sun's rays to produce very high temperatures
- Solar heating, the usage of solar energy to provide process, space or water heating
- Storage heater, an electrical appliance which stores heat at a time when base load electricity is available at a low price
- Water heating, the heating of water for residential, commercial or industrial use
Ventilation: Ventilating or ventilation (V in HVAC) is the process of exchanging or replacing air in any space to provide high indoor air quality which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and other gases. Ventilation removes unpleasant smells and excessive moisture, introduces outside air, keeps interior building air circulating, and prevents stagnation of the interior air. Ventilation includes both the exchange of air to the outside as well as circulation of air within the building.
Categories of ventilation:
- Mechanical ventilation refers to any system that uses mechanical means, such as a fan, to introduce subaerial air to a space. This includes positive pressure ventilation, exhaust ventilation, and balanced systems that use both supply and exhaust ventilation.
- Natural ventilation refers to intentionally designed passive methods of introducing subaerial to a space without the use of mechanical systems. Mechanical systems are more popular for industry. Mechanical systems are able to regulate other things, including temperature, relative humidity, and oxygen levels.
- Mixed mode ventilation (or hybrid ventilation) systems use both natural and mechanical processes.
- Infiltration is the uncontrolled flow of air from outdoors to indoors through leaks (unplanned openings) in a building envelope. When a building design relies on environmentally driven circumstantial infiltration to maintain indoor air quality, this flow has been referred to as adventitious ventilation.
Air Conditioning: Air conditioning engineers broadly divide air conditioning (A in HVAC) applications into comfort and process.
Comfort applications aim to provide an indoor environment that remains relatively constant in a range preferred by humans despite changes in external weather conditions or in internal heat loads.
Process applications aim to provide a suitable environment for an industrial or a commercial process, regardless of internal heat loads and external weather conditions. Although often in the same comfort range, it is the requirements of the process that determines conditions, not human preference.
In both comfort and process applications, the objective is not only to control temperature (although in some comfort applications this is all that is controlled) but also factors like humidity, air movement and air quality.
Process applications include:
- Hospital operating rooms in which air is filtered to high levels to reduce the risk of infection and the humidity is controlled to limit patient dehydration. Although temperatures are often in the comfort range, some specialist procedures such as open-heart surgery require low temperatures (about 18 °C, 64 °F), and others such as neonatal relatively high temperatures (about 28 °C, 82 °F).
- Cleanrooms for the production of integrated circuits and pharmaceuticals etc. in which extremely high levels of air cleanliness and control of temperature and humidity are required for the success of the process.
- Facilities for breeding laboratory animals. Since many animals normally only reproduce in spring, holding them in rooms which mirror spring-like conditions can cause them to reproduce all year round.
- Aircraft air conditioning. Although nominally aimed at providing comfort for passengers and the cooling of equipment, aircraft air conditioning presents a special process due to the low air pressure outside the aircraft.
