DEF

A system in which a fluid other than the water ultimately drawn from the hot taps passes through the collector.

Record 13 1998-10-29

English

Subject field(s)
  • Pumps
  • Refrigeration Engineering
CONT

The great majority of heat pumps work on the principle of the vapour compression cycle. The main components in such a heat pump system are the compressor, the expansion valve and two heat exchangers referred to as evaporator and condenser. The components are connected to form a closed circuit... A volatile liquid, known as the working fluid or refrigerant, circulates through the four components. In the evaporator the temperature of the liquid working fluid is kept lower than the temperature of the heat source, causing heat to flow from the heat source to the liquid, and the working fluid evaporates. Vapour from the evaporator is compressed to a higher pressure and temperature. The hot vapour then enters the condenser, where it condenses and gives off useful heat. Finally, the high-pressure working fluid is expanded to the evaporator pressure and temperature in the expansion valve. The working fluid is returned to its original state and once again enters the evaporator. The compressor is usually driven by an electric motor and sometimes by a combustion engine.

English

Subject field(s)
  • Security Devices
CONT

An open circuit system is composed of magnetic detectors or contacts that are "normally closed. "That means that their contacts are separated when the door or window is in the normally closed position. When the door or window is opened, the contacts are released, causing them to close. This allows current to flow through the wires, and the alarm sounds. All the contacts and detectors are wired in parallel. This means that current flows ONLY when any contact or detector switch makes contact.

English

Subject field(s)
  • Automatic Control (Machine Tools)
CONT

The closed loop system is similar to the open loop system with the exception that a feedback unit is introduced in the electrical circuit. This feedback unit, generally called a transducer, compares the amount the machine table has been moved by the servo motor with the signal sent by the control unit. The control unit instructs the servo motor to make whatever adjustments are necessary until both the signal from the control unit and the one from the servo unit are equal.... Closed loop numerical control systems are very accurate because the accuracy of the command signal is recorded and there is an automatic compensation for error.
