What is the purpose of the zone control system. What is the purpose of a control zone quizlet The control zone immediately surrounding a haz ardous materials incident that extends far enough to prevent. Control zones will be established for controlling movement of radiation sources and personnel. If the air temperature drops to a point where the coil could freeze the zone control will then cycle the compressor off.
Individual zone control is also helpful for people who prefer a particular area to be warmer or cooler compared to the rest of the space. If no abnormality is observed then the normal operation proceeds for next interval. The purpose of EOLRs is to allow the control system to supervise the field wiring for open or short circuit conditions.
Globe valves have specific directions of water flow. ZONE CONTROL 51 INTRODUCTION The aim of the CBL program is to fix the level of each of the 14 liquid zone controllers LZC. The answer is letter B.
Automated zone control is especially useful in two-story structures where upstairs rooms may easily become overheated. The difference in temperature can even be 2 to 5 degrees. Why are zone control systems used.
The discharge air sensor lets the zone control know temperature the supply air is. Stage controls use a single sensor element to control both heating and cooling functions in a greenhouse zone. Proper commands are generated for correcting the abnormality in protecting the system 2.
The zone thermostats and dampers are. Why dont variable air volume zone systems need any method of controlling excess air. Those parts are what is known as the baffle.
The purpose of the control zone is to differentiate the controlled contaminated area from the noncontrolled uncontaminated area. If the supply air starts to get too warm the zone control will cycle the burners off.
It is used a communication bus and a logic processor to make decisions based on real time data.
Stage controls use a single sensor element to control both heating and cooling functions in a greenhouse zone. If any continuous severe problem occurs system is in abnormal condition. The answer is letter B. That sensor can be located among the plants while the controller can be located more conveniently and safely outside the plant environment for the grower to monitor and change input trigger values. A zone control system uses thermostats to connect to a central control panel to open and shut dampers distributed throughout your ductwork thus blocking or releasing hot or cold air. The use of motorized modulating dampers allows the system to control the air flow automatically. Globe valves have specific directions of water flow. Mottola has developed a new system of driving he calls the Zone Control System and its been accepted by a number of prominent driver educators as a state-of-the-art method of teaching drivers how to be sensitive to changes in the. March 24 2020 Dampers.
An area used for dumping excess air and capacity when only one zone is calling zone dampers are usually operated by a small gear motor the operation of a zone system is controlled by a zone controller. Mottola has developed a new system of driving he calls the Zone Control System and its been accepted by a number of prominent driver educators as a state-of-the-art method of teaching drivers how to be sensitive to changes in the. Control zones will be established for controlling movement of radiation sources and personnel. March 24 2020 Dampers. The discharge air sensor lets the zone control know temperature the supply air is. Sometimes the purpose is maintaining acceptable temperatures for a process eg a data center. A zone control system uses thermostats to connect to a central control panel to open and shut dampers distributed throughout your ductwork thus blocking or releasing hot or cold air.
