Onsitego Technical Manager Interview Questions and Answers

The measuring unit of different types of sensors in air conditioners is typically in temperature units such as Celsius or Fahrenheit.

• Temperature sensors in air conditioners measure in Celsius or Fahrenheit

• Humidity sensors measure in percentage

• Pressure sensors measure in Pascals or PSI

• Some sensors may also measure in volts or amps

The refrigeration cycle is a process in which a refrigerant absorbs heat from a low-temperature space and releases it in a high-temperature space.

• The refrigeration cycle involves four main components: compressor, condenser, expansion valve, and evaporator.

• The refrigerant starts as a low-pressure gas in the evaporator, where it absorbs heat from the space being cooled.

• The compressor then compresses the refrigerant into a high-pressure gas, which moves to the condenser where it...read more

TDS in water purifier stands for Total Dissolved Solids, which refers to the combined content of all inorganic and organic substances in water.

• TDS includes minerals, salts, metals, cations, anions, and other dissolved substances in water.

• It is measured in parts per million (ppm) or milligrams per liter (mg/L).

• High TDS levels can affect the taste and quality of water, as well as the performance of water purification systems.

• Water purifiers use various technologies like RO (Rev...read more

Inverter technology is a power conversion technology that controls the speed of a compressor motor to regulate the temperature efficiently.

• Inverter technology is commonly used in air conditioners and refrigerators to adjust the compressor speed based on cooling demand.

• It helps in reducing energy consumption and maintaining a more consistent temperature.

• Inverter technology allows for quieter operation compared to traditional on/off compressor systems.

• It provides faster cooling...read more

A pre carbon filter is a type of filter used to remove impurities and contaminants from water before it passes through a carbon filter.

• Pre carbon filters are typically used in water filtration systems to improve the efficiency and lifespan of the carbon filter.

• They help to remove larger particles and sediments that can clog the carbon filter, allowing it to focus on removing smaller impurities like chemicals and odors.

• Pre carbon filters can be made from various materials such...read more
