Refrigeration cycle is a process of removing heat from a low-temperature reservoir and transferring it to a high-temperature reservoir.

• The cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.

• The refrigerant is compressed by the compressor and then condensed in the condenser, releasing heat.

• The high-pressure liquid refrigerant then passes through the expansion valve, where it expands and evaporates, absorbing heat.

• The low-pressure ref...read more

To start the unit, the process involves checking the power supply, setting the thermostat, and turning on the unit.

• Check the power supply and ensure it is connected and functioning properly.

• Set the thermostat to the desired temperature.

• Turn on the unit and wait for it to start up.

• Monitor the unit to ensure it is running smoothly and efficiently.

BMS Devices list includes DPS, DPT, temperature sensors, fire dampers and other devices used in Building Management Systems.

• BMS Devices list is a comprehensive list of devices used in Building Management Systems.

• DPS (Differential Pressure Sensors) are used to measure the difference in pressure between two points.

• DPT (Differential Pressure Transmitters) are used to measure the pressure difference and transmit the data to the control system.

• Temperature sensors are used to measu...read more

PID loops are a type of control loop feedback mechanism used in systems to maintain a desired setpoint by adjusting the process inputs.

• PID stands for Proportional-Integral-Derivative, which are the three control terms used in the loop.

• Proportional term responds to the current error value.

• Integral term deals with the accumulation of past errors.

• Derivative term predicts future errors based on the rate of change.

• PID loops are commonly used in industrial automation, robotics, and...read more

BMS stands for Building Management System. It is a computer-based control system that manages and monitors a building's mechanical and electrical equipment.

• BMS controls and monitors HVAC systems, lighting, security, fire alarms, and other building systems.

• It typically consists of sensors, controllers, communication networks, and user interfaces.

• Examples of BMS vendors include Siemens, Honeywell, and Johnson Controls.

Superheat is the temperature of a vapor above its saturation temperature in a refrigeration system.

• Superheat is the difference between the actual temperature of the refrigerant vapor and its saturation temperature at a given pressure.

• It is important in refrigeration systems to prevent liquid refrigerant from entering the compressor, which can cause damage.

• Superheat is typically measured in degrees Fahrenheit or Celsius.

• Proper superheat levels ensure efficient operation and pr...read more

Intercompany refers to transactions that occur between two or more entities within the same company or corporate group.

• Intercompany transactions are common in multinational corporations to transfer goods, services, or funds between subsidiaries.

• These transactions must be recorded accurately to ensure proper financial reporting and compliance with tax regulations.

• Intercompany eliminations are necessary to avoid double counting of revenues and expenses in consolidated financial...read more

The collection cycle refers to the process of collecting outstanding debts from customers.

• The cycle begins with sending invoices to customers for payment.

• If payment is not received by the due date, a reminder is sent to the customer.

• If payment is still not received, a collection call is made to the customer.

• If the debt remains unpaid, the account may be sent to a collection agency.

• The cycle ends when the debt is paid in full or written off as uncollectible.
