DenverProper distribution of air in a specific room is characterized by the manner of introducing air into it, giving the air an avenue to flow through, and removing it from the spaces. Largely, the airflow within spaces using HVAC-heating, ventilation, air conditioning-is categorized into two varied styles. One style is displacement while the other one is mixing, otherwise known as dilution.HVAC, the Air and the Displacement Method The air, when using the HVAC displacement method, is introduced at lower speeds. This causes a minimal need for induction as well as mixing. The outlets designated for displacement are typically situated somewhere close to the floor. The so-called buoyancy forces in that certain room, which are produced by heat sources such as lighting, people, electrical equipments and computers are utilized to move the contaminants and the heat from the inhabited zone into the drain grills or into the return. In doing so, the quality of the air in the particular places that are occupied is expected to be of much better quality when compared to the air quality from a room with which it is mixing. Air mixing is preferred for some floor level areas. This system of distributing the air is termed as UFAD or underfloor air condition. Meanwhile, if this method is not favorable, then it is called displacement. HVAC and the Room-It's All in the Air Any occupied space has a greater chance of improving indoor air quality. This is better known as the Indoor Air Quality, or IAQ. Thermal comfort may also be improved if the displacement method is used. The difference between the air density in the upper zone, which is usually contaminated, and the air density in the lower zone, which appears to be clean, is also addressed by this method.Heating it Up with HVAC Mixing Systems In HVAC mixing systems, the air supply in the occupied room is mixed to establish a comfortable environment. This simply means that the supply of cool air in the cooling mode, which is usually in a design condition of 55°F, induces the room air in providing opportunities for mixing as well as the equalization of the temperature by leaving the passage at a high speed. Temperature changes are less noticeable while the concentration of the contaminant is expected to be somewhat uniform throughout the room once the airflow is mixed completely. A passage for air is normally situated at or near floor level and the air is made available directly into the area that is currently populated. The air that is being supplied for the whole area is then spread entirely and eventually increases once it is intensified by the heat sources present within the vicinity. Meanwhile, returns are naturally found in areas near the ceiling and wear out the warm air that is obviously contaminated.
Important Furnace Repair Tips for Your HomeTo fix household things that break, you need to know how it works, what can go wrong, how to identify the problem, as well as the steps to fixing it. Here's what you need to know about gas furnace repairs.How Does It Work?Natural or propane gas from an outside source is piped to the furnace where it is burned to produce heat. Usually a fan-driven forced-air distribution system blows the warmed air through ducts that vent into the various rooms of the house. Older gas furnaces use a standing-pilot ignition. Maintenance involves turning off the pilot each spring and relighting it each fall. Newer, more efficient gas furnaces use an electric spark to light the gas as necessary.What Can Go Wrong?Most gas furnaces are quite reliable. What are the symptoms of problems? The furnace may not produce heat or may not produce enough heat. The pilot light may go out repeatedly or refuse to light. The thermocouple may be faulty. The pilot may light but not ignite the burner. The furnace may be noisy. There are some maintenance and a few minor repairs that you can make. However, major service should be left to a trained technician.Fix-It TipTo minimize problems with your gas furnace, take time each month to check the air filter and clean or replace it if necessary. Once a year, clean the blower blades, lubricate the blower motor, and inspect the belt.How Can I Identify the Problem? If there is no heat, check the electrical service panel for a burned fuse or tripped breaker. Relight the pilot light (see below).If there is not enough heat, adjust the burner air shutter (see below); and clean the burner ports (see below).If the pilot light does not light or does not stay lit, clean the pilot orifice carefully with a toothpick, test the thermocouple and replace it if it is faulty (see below).If the flame flickers, adjust the pilot (see below).If there is an exploding sound when the burner ignites, adjust the pilot to a higher setting and clean the pilot orifice and the burner ports.If the burner takes more than a few seconds to ignite, clean the pilot orifice and adjust the pilot light.If the burner flame is uneven, clean the burner ports. If the burner flame is very yellow, clean the burner; open vents in the furnace room to provide more air; adjust the burner air shutter.If the furnace makes a rumbling noise when the burners are off, clean the burner and adjust the burner air shutter.If the air is too dry, wash or replace the evaporator pad if you have a humidifier; test the humidistat; and adjust the water-level float to raise the water level.If some rooms are too cool and others too warm, the distribution system may require balancing. Refer to the Forced-Air Distribution Fix-It Guide at FixItClub.comFix-It TipBe sure your filter is the right size for your furnace.What Parts, Materials, and Tools Do I Need?Some replacement parts for gas furnaces are interchangeable (filters, fasteners) and available at your local hardware store. Others, such as burners and controls, must be purchased from the manufacturer or aftermarket supplier or through a heating equipment supplier listed in your local telephone book.The primary tools you will need for fixing a gas furnace include these:* Screwdrivers* Wrenches* Pliers* Wire brush* MultimeterWhat Are the Steps to Fixing It?To light the pilot on a standing-pilot (always on) ignition system, follow the lighting instructions located near the control. Otherwise, try these steps:Light the pilot:1. Press and hold the pilot control knob to start the pilot. Set the control knob to the pilot position. Hold a long match under the pilot gas port.2. Press the control knob; the pilot should light. Hold the control knob down until the flame is burning brightly (about 30 seconds). Release pressure on the knob, and turn it to the on position.3. If the pilot goes out when you release the control knob, try relighting, holding the control knob down longer. If the pilot again goes out, check the thermocouple (below).Adjust the pilot:1. Remove any cap covering the pilot adjusting screw on a combination control. 2. Turn the adjusting screw counterclockwise to increase the flame or clockwise to decrease it. It is correctly adjusted when the flame envelops the thermocouple bulb by 1/2 inch and appears dark blue with a small yellow tip.Test and replace a thermocouple:1. Hold the control knob to pilot and light the pilot as above.2. Unscrew the thermocouple fitting with an open-ended wrench.3. Set a multimeter to the DVC (lowest voltage) scale.4. Clip one multimeter lead to the end of the thermocouple tube nearest the pilot and the other lead to the fitting on the other end of the tube.5. If the multimeter shows a reading besides zero, the thermocouple is functioning. Replace the thermocouple tube.6. If there is no reading, you will need to clean or replace the thermocouple following steps 7 through 11.7. Release the control knob and shut off the main gas valve on the gas-supply pipe that leads into the burner. Shut off power to the burner at the electrical service panel .8. Remove the thermocouple from its mounting bracket.9. Wipe the combination control clean and install a new thermocouple, tightening it by hand, then give it a one-quarter turn with a wrench.10. Insert the thermocouple into the pilot bracket, being careful to not crimp the tubing.11. Turn on power to the furnace and relight the pilot (above).
