VMD CAD & Graphic Technologies Mechanical Engg. Design Interview Questions and Answers

The basic refrigeration cycle is a thermodynamic cycle that involves the transfer of heat from a low temperature region to a high temperature region.

• The refrigerant absorbs heat from the low temperature space (evaporation)

• The refrigerant is compressed, raising its temperature and pressure

• The refrigerant releases heat to the high temperature space (condensation)

• The refrigerant expands, lowering its temperature and press

Humidity, WBT, and DBT are important parameters in the field of HVAC and air conditioning.

• Humidity refers to the amount of water vapor present in the air.

• WBT (Wet Bulb Temperature) is the temperature read by a thermometer covered in a water-soaked cloth over which air is passed.

• DBT (Dry Bulb Temperature) is the temperature of air measured by a regular thermometer.

• These parameters are crucial in determining the comfort ...read more

Heat load calculations involve determining the amount of heat that needs to be added or removed from a space to maintain a desired temperature.

• Components include heat gain from occupants, equipment, lighting, and infiltration, as well as heat loss through walls, windows, and roofs.

• Calculations are typically done using formulas based on the specific heat capacities and thermal properties of materials.

• Example: In HVAC de...read more
