Heat Recovery Ventilation

Introduction

Heat recovery ventilation, also known as HRV, mechanical ventilation heat recovery, or MVHR, is an energy recovery ventilation system using equipment known as a heat recovery ventilator, heat exchanger, air exchanger, or air-to-air heat exchanger which employs a counter-flow heat exchanger (countercurrent heat exchange) between the inbound and outbound air flow.
HRV provides fresh air and improved climate control, while also saving energy by reducing heatin ....etc

Abstract
An alternative method of distributing RF in buildings is proposed in which the heating and ventilation ducts are used as waveguides. Because of the relatively low waveguide loss, this method may lead to more efficient RF distribution than possible with radiation through walls or the use of leaky coax. Further, the use of existing infrastructure could lead to a lower-cost system. Initial experimental results are pr ....etc

How does it work?
Cooling and air conditioning used to cool products or construction environment.
Refrigeration system or air conditioning heat from a cold into a warm layer of low energy high energy reservoir
There are several heat transfer loop cooling system, as shown in Figure 2. Heat energy moves from left to right, which is derived from the area and expelled into the air through five loops of heat transfer:
Indoor air loop. In the left loop, the air is fresh air through the cooling coil, where it transfers its heat to chilled water. Then ....etc

Introduction

HVAC (Heating, Ventilating, and Air Conditioning) refers to technology of indoor or automotive environmental comfort. HVAC system design is a major subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).
HVAC is particularly important in the design of medium to large industrial and office build ....etc

ABSTRACT

It is the established fact that only about 30% of heat supplied by the fuel is converted into useful work, in case of internal combustion (I.C) engines and the rest is going waste to the atmosphere in the form of coolant losses (35%) and exhaust gas losses (35%). The conventional air con ....etc

Air conditioning (often referred to as AC, A.C., or A/C) is the process of altering the condition of air by removing heat and humidity to achieve a more comfortable interior environments, typically with the aim of distributing the conditioned air to an occupied space such as a building or a vehicle to improve thermal comfort and indoor air quality. In common use, an air conditioner is a device that removes heat from the air inside a building or vehicle, thus lowering the air temperature. The cooling is typically achieved through a refrigeration ....etc
