They are normally made of GI sheets,fiber glass lined. TYPE OF DUCTS SUPPLY AIR DUCT RETURN AIR DUCT FRESH AIR …
Air Distribution system Is the Distribution of Conditioned Air in Buildings and Rooms in Order to Maintain Temperatures, Humidity and Air Velocities within Occupied Space at Acceptable Conditions. It includes air handlers, ductwork, and associated components for heating, ventilating, and air-conditioning buildings. Types of Air Distribution Constant-volume systems (CV) operate at a constant airflow rate; …
normally has profiled blades to direct the air at an angle as it leaves the unit into the space . Alternately ,Grille is used for vertical discharge -they are fabricated of aluminum, stainless steel ,plastic painted or chromated. they come in different shapes like bar,egg,linear,louver depending on its application. TYPES OF DIFFUSERS/GRILL Lover Bladed Diffuser these are …
A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water’s temperature. As this occurs, a small volume of water is evaporated, reducing the temperature of the water being circulated through the tower. Cooling tower acts as the cooling …
is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. Usually enclosed in a large insulated box containing fans/blowers , dampers, filter,heat exchangers (evaporator), humidifiers , mixing box and its controls. Used to control temperature , humidity , air movement and air cleanliness TYPES OF AIR HANDLING UNIT (AHU) …
Split air conditioner comprises of two parts: the outdoor unit and the indoor unit. The outdoor unit, fitted outside the room, houses components like the compressor, condenser and expansion valve. The indoor unit comprises the evaporator or cooling coil and the cooling fan. Advantage Lower Noise and Vibration Level Requires only a hole on the wall …
Description & Components is the most commonly used air conditioner for single rooms. In this air conditioner all the components, namely the compressor, condenser, expansion valve or coil, evaporator and cooling coil are enclosed in a single box. Advantage: Low Cost All component parts contained in one box Eco friendly ,uses less refrigerant Practically easy to install and maintain …
PSYCHROMETRY is the science of studying the thermodynamic properties of moist air and the use of these properties to analyze conditions and processes involving moist air. Moist air is a mixture of dry air and water vapour. In atmospheric air, water vapour content varies from 0 to 3% by mass. Is often used in the …
The cycle uses the Carnot Refrigeration cycle and operates as follows. State 1 is the state after the refrigerant passes through an evaporator (D), where warm air heats the fluid and converts it completely to vapor. State 2 is the state after the fluid passes through a compressor (A) which increases the fluid’s pressure and temperature up …
