Heating, ventilation and air conditioning (HVAC) encompasses the overall technology that is associated with indoor and vehicular comfort control. HVAC is an important part of residential structures, such as:
- Single family homes
- Apartment buildings
- Senior living facilities
- Industrial & office buildings
- Ships & submarines
HVAC is also commonly utilized in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity using fresh outdoor air.
A well-maintained HVAC system will provide extended efficiency and reliability for many years. There are numerous types of HVAC parts and components that make up an entire system. The following HVAC components make up an HVAC maintenance system:
- Thermostat - The thermostat is usually the most visible part of your HVAC system. Set on a prominent, easily accessible wall, it may be either programmed in advance or set manually to keep the home at a desired temperature.
- Heat Exchanger - The heat exchanger is found inside your furnace unit's housing. This component switches on when the furnace is activated by thermostat to produce warmer temperatures in winter.
- Condensing Unit – This component is connected to the evaporator coil. When the refrigerant has been cooled to a liquid by heat exchange with the exterior air, the condensing unit pumps the liquid to the evaporator coil to be evaporated into a gas once more.
- Evaporator Coil – This HVAC part is located within a metal enclosure on the furnace's exterior, to the top or side, the evaporator coil works similarly to an automobile radiator to produce cool air, which is then circulated through the ductwork.
- Ductwork – These highly useful HVAC components transport air warmed or cooled by the system to the various areas of the structure.
- Refrigerant Lines - Refrigerant lines carry a refrigerant substance to the condensing unit vaporized in the form of a gas and return it to the evaporator coil in liquid form.
- Vents - Vents transfer the heated or cooled air from the duct system into the individual rooms of the structure being heated or cooled.
Choosing an HVAC Pressure Switch
An HVAC pressure switch
is a protective device that is installed in both heating and cooling systems. The switch will open and cause the system to stop operating under certain conditions which may hurt the system. Pressure switches are commonly tripped by occurrences like clogged vents or hoses, dirty filters or condenser coils. The exact type of application that your HVAC pressure switch will be used for will determine the style of HVAC pressure switch and HVAC components that you will require.
Types of HVAC Pressure Switches
The design and number of HVAC pressure switches your system has depends on whether it uses conventional or condensing technology. There are several different types of HVAC washers
and pressure switches that can be utilized to provide your system with proper efficiency and reliability. These pressure switches, include:
- A single-stage conventional system has one hose leading from the draft inducer fan to the pressure switch.
- A single-stage condensing system has two hoses on the pressure switch, one to sense pressure at the draft inducer and another for sensing venting pressure at the condensate collector box.
- A two-stage system may have two pressure switches.
- A modulating system may have three pressure switches.
