Thermal wheel, the Glossary

Index Thermal wheel

A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop units or in the exhaust gases of an industrial process, in order to recover the heat energy.[1]

Adsorption

Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface.

See Thermal wheel and Adsorption

Air handler

An air handler, or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system.

See Thermal wheel and Air handler

Chrysler

FCA US, LLC, doing business as Stellantis North America and known historically as Chrysler, is one of the "Big Three" automobile manufacturers in the United States, headquartered in Auburn Hills, Michigan.

Countercurrent exchange

Countercurrent exchange is a mechanism occurring in nature and mimicked in industry and engineering, in which there is a crossover of some property, usually heat or some chemical, between two flowing bodies flowing in opposite directions to each other.

See Thermal wheel and Countercurrent exchange

Desiccant

A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant.

See Thermal wheel and Desiccant

Energy recovery

Energy recovery includes any technique or method of minimizing the input of energy to an overall system by the exchange of energy from one sub-system of the overall system with another.

See Thermal wheel and Energy recovery

Enthalpy

Enthalpy is the sum of a thermodynamic system's internal energy and the product of its pressure and volume.

See Thermal wheel and Enthalpy

Fouling

Fouling is the accumulation of unwanted material on solid surfaces.

See Thermal wheel and Fouling

Fuel efficiency

Fuel efficiency (or fuel economy) is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work.

See Thermal wheel and Fuel efficiency

Gas turbine

A gas turbine, gas turbine engine, or also known by its old name internal combustion turbine, is a type of continuous flow internal combustion engine.

See Thermal wheel and Gas turbine

Heat of combustion

The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it.

See Thermal wheel and Heat of combustion

Heat pipe

A heat pipe is a heat-transfer device that employs phase transition to transfer heat between two solid interfaces.

See Thermal wheel and Heat pipe

Heat recovery ventilation

Heat recovery ventilation (HRV), also known as mechanical ventilation heat recovery (MVHR) or energy recovery ventilation (ERV), is a ventilation system that recovers energy by operating between two air sources at different temperatures. Thermal wheel and heat recovery ventilation are energy recovery.

See Thermal wheel and Heat recovery ventilation

Heating, ventilation, and air conditioning

Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space.

See Thermal wheel and Heating, ventilation, and air conditioning

Humidifier

A humidifier is a household appliance or device designed to increase the moisture level in the air within a room or an enclosed space.

See Thermal wheel and Humidifier

Humidity

Humidity is the concentration of water vapor present in the air.

See Thermal wheel and Humidity

Hybrid vehicle

A hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged.

See Thermal wheel and Hybrid vehicle

Hygroscopy

Hygroscopy is the phenomenon of attracting and holding water molecules via either absorption or adsorption from the surrounding environment, which is usually at normal or room temperature.

See Thermal wheel and Hygroscopy

Indoor air quality

Indoor air quality (IAQ) is the air quality within buildings and structures.

See Thermal wheel and Indoor air quality

Latent heat

Latent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process—usually a first-order phase transition, like melting or condensation.

See Thermal wheel and Latent heat

Molecular sieve

A molecular sieve is a material with pores of uniform size.

See Thermal wheel and Molecular sieve

Partial pressure

In a mixture of gases, each constituent gas has a partial pressure which is the notional pressure of that constituent gas as if it alone occupied the entire volume of the original mixture at the same temperature.

See Thermal wheel and Partial pressure

Queen's University at Kingston

Queen's University (Kingston, Ontario), commonly known as Queen's University or simply Queen's, is a public research university in Kingston, Ontario, Canada.

Recuperator

A recuperator is a special purpose counter-flow energy recovery heat exchanger positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, in order to recover the waste heat. Thermal wheel and recuperator are energy recovery, heat exchangers and industrial equipment.

See Thermal wheel and Recuperator

Regenerative heat exchanger

A regenerative heat exchanger, or more commonly a regenerator, is a type of heat exchanger where heat from the hot fluid is intermittently stored in a thermal storage medium before it is transferred to the cold fluid. Thermal wheel and regenerative heat exchanger are energy recovery and heat exchangers.

Run-around coil

air handling units on the roof of an office building A run-around coil is a type of energy recovery heat exchanger most often positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, to recover the heat energy. Thermal wheel and run-around coil are energy recovery and industrial equipment.

Sensible heat

Sensible heat is heat exchanged by a body or thermodynamic system in which the exchange of heat changes the temperature of the body or system, and some macroscopic variables of the body or system, but leaves unchanged certain other macroscopic variables of the body or system, such as volume or pressure.

See Thermal wheel and Sensible heat

Silica gel

Silica gel is an amorphous and porous form of silicon dioxide (silica), consisting of an irregular tridimensional framework of alternating silicon and oxygen atoms with nanometer-scale voids and pores.

See Thermal wheel and Silica gel

Thermal comfort

Thermal comfort is the condition of mind that expresses subjective satisfaction with the thermal environment.

See Thermal wheel and Thermal comfort

Waste heat

Waste heat is heat that is produced by a machine, or other process that uses energy, as a byproduct of doing work.

See Thermal wheel and Waste heat

Windcatcher

A windcatcher, wind tower, or wind scoop (بادگیر) is a traditional architectural element, originated in Iran (Persia), used to create cross ventilation and passive cooling in buildings.
