What are the properties of HVAC?

One of the most common properties measured in the HVAC control is temperature. The principle of measurement involves- the thermal expansion of metal or gas and a calibrated change in electrical characteristics. Below are common types of temperature sensors:

What is a self contained HVAC system?

HVAC systems are classified as either self-contained unit packages or as central systems. Unit package describes a single unit that converts a primary energy source (electricity or gas) and provides final heating and cooling to the space to be conditioned. Examples of self-contained unit packages are rooftop HVAC systems, air conditioning units for rooms, and air-to-air heat pumps. With central systems, the primary conversion from fuel such as gas or electricity takes place in a central location, with some form of thermal energy distributed throughout the building or facility. Central systems are a combination of central supply subsystem and multiple end use subsystems. There are many variations of combined central supply and end use zone systems. The most frequently used combination is central hot and chilled water distributed to multiple fan systems. The fan systems use water-to-air heat exchangers called coils to provide hot and/or cold air for the controlled spaces. End-use subsystems can be fan systems or terminal units. If the end use subsystems are fan systems, they can be single or multiple zone type. The multiple end use zone systems are mixing boxes, usually called VAV boxes.

What is open loop control?

Open loop control is a system with no feedback i.e. there is no way to monitor if the control system is working effectively. Open loop control is also called feed forward control.

What is a direct acting thermostat?

The simplest form of controller is direct-acting, comprising a sensing element which transmits power to a valve through a capillary, bellows and diaphragm. The measuring system derives its energy from the process under control without amplification by any auxiliary source of power which makes it simple and easy to use. The most common example is the thermostatic radiator valve which adjusts the valve by liquid expansion or vapor pressure. Direct-acting thermostats have little power and have some disadvantages but the main advantage is individual and inexpensive emitter control. Direct-acting thermostatic equipment gives gradual movement of the controlling device and may be said to modulate.

How does HVAC control work?

Most of HVAC plant control takes place through control valves regulating steam or hot/chilled water flow as the means of trimming heat transfer therefore their characteristics, sizing and selection are extremely important.

What is an electric control?

Electric controlled devices provide ON / OFF or two-position control. In residential and small commercial applications, low voltage electrical controls are most common. A transformer is used to reduce the 115 volt alternating current (AC) to a nominal 24 volts. This voltage signal is controlled by thermostats, and can open gas solenoid valves, energize oil burners or solenoid valves on the DX cooling, control electric heat, operate two position valves and damper or turn on-off fans and pumps. A relay or contactor is used to switch line voltage equipment with the low voltage control signal. The advantage of electric system is that it eliminates the personnel safety and fire risk associated with line voltage, and allows these control wires to be installed by a non-electrician without requiring conduit and other safety measures. However, these systems are generally limited to providing on/off control only: they cannot operate at half capacity.
