State Policy directs that State Buildings will not be heated above 68 degrees during the winter and 78 degrees during the summer, except in areas where more stringent temperature control is required by law or specialized needs of equipment or experimentation.\u00a0<\/strong><\/p>\n
Nature of Work<\/strong><\/span><\/u>:<\/p>\n
Heating and air-conditioning systems control the temperature, humidity, and the total air quality in residential, commercial, industrial, and other buildings.\u00a0 Heating, air-conditioning, and refrigeration mechanics and installers\u2014also called technicians\u2014install, maintain and repair such systems.\u00a0 Because heating, ventilation, air-conditioning, and refrigeration systems often are referred to as HVACR systems, these workers also may be called HVACR technicians.<\/p>\n
Heating, air-conditioning, and refrigeration systems consist of many mechanical, electrical, and electronic components, such as motors, compressors, pumps, fans, ducts, pipes, thermostats, and switches.\u00a0 In central forced air heating systems, for example, a furnace heats air, which is then distributed through a system of metal or fiberglass ducts.\u00a0 Technicians maintain, diagnose, and correct problems throughout the entire system.\u00a0 To do this, they adjust system controls to recommended settings and test the performance of the system using special tools and test equipment.<\/p>\n
Technicians often specialize in either installation or maintenance and repair, although they are trained to do both.\u00a0 They also may specialize in doing heating work or air-conditioning or refrigeration work.<\/p>\n
Technicians follow blueprints or other specifications to install oil, gas, electric, solid-fuel, and multiple-fuel heating systems and air conditioning systems.\u00a0 After putting the equipment in place, they install fuel and water supply lines, air ducts and vents, pumps, and other components.\u00a0 They may connect electrical wiring and controls and check the unit for proper operation.<\/p>\n
Technicians also install and maintain heat pumps, which are similar to air conditioners but can be reversed so that they both heat and cool.<\/p>\n
Heating, air-conditioning, and refrigeration mechanics and installers are adept at using a variety of tools to work with refrigerant lines and air ducts, including hammers, wrenches, metal snips, electric drills, pipe cutters and benders, measurement gauges, and acetylene torches.\u00a0 They use voltmeters, thermometers, pressure gauges, manometers, and other testing devices to check airflow, refrigerant pressure, electrical circuits, burners, and other components.<\/p>\n
Heating and Cooling Controls:<\/strong><\/p>\n
MD Building Classrooms<\/strong><\/p>\n
Every classroom in the MD Building has one of these controllers (see below) on the wall. This controller will give you the ability to fine tune the classroom air temperature more to your liking. The temperature settings are 68<\/span> degrees for heating and 74<\/span> degrees for cooling when the indicator on the controller dial is at the 12 o’clock position. This means that if the room temperature drops below 68, the heating will activate. If the room temperature rises above 74, the cooling will activate. The air flow to the classroom never stops during hours of operation so there will always be fresh air coming in even if the heating or cooling is not activated. When the dials is turned clockwise the set points will be raised. When the dial is turned counter clockwise the set points will be lowered. The set points can be raised or lowered two (2) degrees + or -.<\/p>\n
![\"\"](\"https:\/\/www.palomar.edu\/facilities\/images\/MDTstat.jpg\")
<\/strong><\/p>\nEXAMPLE:<\/span> The dial is turned all the way<\/u> clockwise. The set points change from (<\/span>68 <\/span>\/ 74) to (<\/span>70<\/span> \/<\/span> 76). If the dial is turned halfway<\/u> counter clockwise the set points change from (<\/span>68 <\/span>\/ 74) to (<\/span>67 <\/span>\/ 73). If the room temperature is not to your liking check the setting on the controller. It may have been changed by the occupants before you.<\/span><\/p>\n
EXTERIOR WINDOW SENSORS<\/p>\n
When any of the classroom windows are open, the heating and cooling is shut off and the air flow from the heating and cooling system is stopped in that classroom. This allows the classroom to be heated or cooled by the outside air while saving energy. If you think your classrooms heating and air conditioning system is not working you should check to see if the windows are closed before requesting service<\/span>.<\/p>\n
MD Building Offices<\/strong><\/span><\/p>\n
Every office in the MD building has one of these controllers on the wall. This controller will give you the ability to fine tune your office air temperature more to your liking. There are multiple controllers linked to ten different systems. The controllers are in groups that range from four controllers on one system to twenty two. In each group there is one controller that is the master. The master controller determines whether the system is in heating or cooling as well as controlling the air damper in that particular office. The slave controllers on the system control the air dampers which are in the ceiling registers in their respective offices. The controllers have a snow flake on the left and a flame on the right. When the dial indicator on the master is at the twelve o\u2019clock position the heat setting for the system is <\/span>68<\/span> and the cool setting is <\/span>74<\/span>. When the dial is turned to the right (flame) the system temperatures will increase. When turned to the Left (snowflake) the system temperatures will decrease. The amount of control is relative to how far the dial is turned left or right with a maximum of two degrees either way. The same applies to the slave controllers except when the dial indicator is in the twelve o\u2019clock position the heating and cooling set points are representative of what the master controller is set at.\u00a0 You can adjust your office controller up to two degrees warmer or cooler from that setting.<\/span><\/p>\n
![\"\"](\"https:\/\/www.palomar.edu\/facilities\/images\/HVACMDOffices.jpg\")
<\/span><\/p>\nEXAMPLE: \u00a0The master controller has been calling for heat so there is warm air coming out of all the registers on your system. Your office has now warmed to the relative setting on your controller so the controller tells the damper in your ceiling register to close down to slow the flow of warm air into your office. Depending on how far off your controllers setting is from the masters setting your damper may close all the way or just a little. When the master controller is calling for cooling the entire system will be blowing cool air. The damper will again adjust to maintain the setting on your controller. This time closing to make your office warmer and opening to make it cooler. If multiple offices on your system are to warm or to cold check the master controller for your system. It may be set to far right or left.<\/p>\n
The exterior windows in the offices are linked to the air dampers that are located in the ceiling registers in their respective offices. When the windows are open the damper will close and the air flow to the office will stop. This allows you to heat or cool your office with outside air while saving energy.<\/p>\n
