Heat Pump, Heating and Cooling, heat absorption, Heat transmission

Heat Pump  Description: Heat pumps provide an energy-efficient substitute for furnaces and air conditioners in regions with moderate heating and cooling requirements. Heat pumps, which work similarly to refrigerators, transfer heat from a cool area into a warm area using electricity, making the cool area colder and the warm area warmer. Heat pumps transfer heat from a cool house into a warm one during the heating season and from a cool house into a warm one during the cooling season. Heat pumps can produce up to four times as much energy as they use because they transfer heat rather than create it.   HEAT PUMP -:  Heat pump extracts heat from cool outside air and pumps it into your home. To achieve this, a compressor inside the unit uses electricity to increase the temperature of the heat it extracts from the outside air. Heat pumps also provide a cooling effect by pumping warm indoor air outdoors.   Types of Heat Pump: Heat Pump operates on Vapo...

Cooling Tower Terminology or Cooling tower water parameter.

 Cooling Tower:   Terminology of Cooling Tower: Below are the most important parameters of cooling tower which are affecting the cooling tower efficiency:- Range Approach Wet Bulb temperature COC (Cycle of Concentration) Evaporation loss Drift loss Blow Down Makeup water TDC Hardness   Range: Range is defined as the temperature difference between the cooling tower inlet temperature to the cooling tower outlet temperature. Range is also known as delta-T of cooling tower. Approach: Approach is defined as the temperature difference between the temperature of the cooling water leaving the tower and the wet-bulb temperature of the air entering in cooling tower. Maintaining of the approach define the running temperature range of the cooling tower and approach is an crucial point in cooling tower. Wet Bulb temperature of Cooling tower: Wet bulb temperature is a crucial factor withinside the cycles of cooling towers cooling process. Wet bulb temperatur...

Cleanroom Airlocks, Cleanroom contamination control.

Cleanroom (Airlocks) Air Pressure Balancing Introduction: - HVAC air pressure balancing is an important part of cleanroom HVAC. Balancing the air pressure in a cleanroom ensures that the product manufacturing in one area of the cleanroom does not contaminate products in another area. Pressure balancing prevents cross-contamination of products processed in the cleanroom. Airflow patterns or direction in a cleanroom are entirely dependent on the cleanroom air pressure balancing. Air pressure balancing (Airlocks) in cleanroom maintained in three types. Cascade Airlock Sink Airlock Bubble Airlock Cascade Airlock  Flow: - In the cascade airlock Air flows from higher pressure zone to lower pressure zone in one direction. Cascade airlock having Higher pressure zone on its one side and lower pressure zone on other side. Sink Airlock  Flow: - Sink airlock having a positive pressure zone at both sides of airlock and having negative pressure inside the airlock. In this type of airlock ai...

What GI sheet? Introduction to Galvanized iron. Properties, Composition, Disadvantage.

  Introduction Galvanizing could be a method of coating iron or steel with metallic element so as to supply bigger protection against corrosion for the iron or steel base. the method of galvanic plate iron was developed at the same time in France and European country in 1837. each of those strategies utilized a "hot dipping" method to coat plate iron with metallic element. Like tinplate, early galvanized metals were hand swaybacked. nowadays most Fe and steel is electroplated. The following square measure the foremost common strategies for applying protecting coatings of metallic element to iron and steel: Hot-dip Galvanizing : The immersion of iron or steel in liquified metallic element, once the surface of the bottom metal has been properly clean. This method offers a comparatively thick coating of metallic element that freezes into a crystalline surface pattern called spangles. During the method, a multiple bedded structure of iron- or steel-zinc alloys is created between ...
