    The Air Conditioning and Heating System

    Detailed Compressor Information

    Not only do we depend on our cars to get us where we want to go, we also depend on them to get us there without discomfort. We expect the heater to keep us warm when it's cold outside, and the air conditioning system to keep us cool when it's hot.
    We get heat from the heater core, sort of a secondary radiator, which is part of the car's cooling system. We get air conditioning from the car's elaborate air conditioning system.
    Despite its relatively small size, the cooling system has to deal with an enormous amount of heat to protect the engine from friction and the heat of combustion. The cooling system has to remove about 6,000 BTU of heat per minute. This is a lot more heat than we need to heat a large home in cold weather. It's good to know that some of this heat can be put to the useful purpose of keeping us warm.
    Air conditioning makes driving much more comfortable in hot weather. Your car's air conditioner cleans and dehumidifies (removes excess moisture), the outside air entering your car. It also has the task of keeping the air at the temperature you select. These are all big jobs. How do our cars keep our "riding environment" the way we like it?
    Most people think the air conditioning system's job is to add "cold" air to the interior of the car. Actually, there is no such thing as "cold," just an absence of heat, or less heat than our bodies are comfortable with. The job of the air conditioning system is really to "remove" the heat that makes us uncomfortable, and return the air to the car's interior in a "un-heated" condition. Air conditioning, or cooling, is really a process of removing heat from an object (like air).
    A compressor circulates a liquid refrigerant called Refrigerant-12 (we tend to call it "Freon," a trade name, the way we call copy machines "Xerox" machines). The compressor moves the Refrigerant-12 from an evaporator, through a condenser and expansion valve, right back to the evaporator. The evaporator is right in front of a fan that pulls the hot, humid air out of the car's interior. The refrigerant makes the hot air's moisture condense into drops of water, removing the heat from the air. Once the water is removed, the "cool" air is sent back into the car's interior. Aaaaaah! Much better.
    Sometimes we worry when we catch our car making a water puddle on the ground, but are relieved to discover that it's only water dripping from the air conditioning system's condenser (no color, no smell, and it dries!).
    Note: Refrigerant-12 is extremely dangerous. Many special precautions must be taken when it is present. It can freeze whatever it contacts (including your eyes), it is heavier than air and can suffocate you, and it produces a poisonous gas when it comes in contact with an open flame. Dash Controls


    Most or all of the control panel of your car is located on the dashboard behind the steering wheel. Sometimes it extends onto the car's console, between the two front seats, and onto your steering column. Little duplicate fragments of the control panel are scattered around the interior of your vehicle, such as automatic door locks, extra light switches, etc.
    The dash controls enable you to operate your headlights, turn signals, horn, windshield wipers, heater, defroster, air conditioning, radio, etc. All of the vehicle's controls should be within the reach of the driver.
    The control panel also contains all of your gauges; gas, temperature, tachometer, etc. These enable you to monitor the operating conditions of your engine and charging system, fuel level, oil pressure and coolant temperature. Warning lights come on to alert you to dangerous coolant temperatures, or loss of oil pressure.
    In 1924 the Nash Co. introduced the electric clock as an accessory. Relays


    A relay is an electromagnetic device in which contacts are made and subsequently broken. An example of this would be your car's horn.
    By natural law, the farther electrical current travels, the lower its voltage becomes. Your car horn has to be connected to the car battery in order to sound. The shortest distance between two points is a wire connecting your horn to your battery. The only problem with this arrangement is that connecting the two would give you a permanent horn blast when you turned the key in your ignition.
    This is an unacceptable arrangement, so a relay is included in the connection. The relay stops the horn from sounding until you activate the relay by pressing the horn. The relay then allows the horn to connect to the battery, or complete the circuit, and it sounds. As soon as you stop pressing the horn, the relay breaks the connection, or circuit, and presto-- no more horn!
    Relays, with switches, are used for most of the equipment that depends on the battery for an energy source. This includes headlights, taillights, radio, etc.
    In 1922, a Model T was the first car equipped with a radio. In 1927, the first commercially produced car radio came on the scene.
    A "relay" is any switching device operated by a low current circuit that controls opening and closing of another circuit of high current capacity. The purpose of the "cutout relay" is to prevent the battery from discharging through the generator when the engine is stopped or turning over slowly. A "field relay" connects the alternator field windings and voltage regulator windings directly to the battery. Heater/AC Blower Motor



    The blower motor is the motor that turns the electric fan in an air conditioning or heating system. Air Ducts



    The air ducts control the passage of hot or cold air into the interior of the car. They are operated by a control on the dash, either manually or automatically. Controls



    Most air conditioning/heating systems have three possible air settings. One is to recirculate the air that is in the car, a second is to use only air from the outside of the car, and a third is to mix some of the outside air with the air recirculating inside the car. Low Pressure Line



    The low pressure line is a hose, or tube containing refrigerant that connects the evaporator to the air conditioning system's compressor. The compressor draws the low pressure refrigerant from the evaporator in through the low pressure line in order to compress it. High Pressure Line



    The high pressure line is a hose, or tube containing refrigerant that connects the air conditioning system's compressor to the condenser. The compressor forces the compressed refrigerant into the condenser through the high pressure line.

Our air conditioning system is one of those examples.
    We know we have heating and air conditioning and some of us are aware of changing or cleaning the air conditioning filters, but what are all the air conditioning parts that work together to provide central air conditioning in residential, commercial and industrial air conditioning? And why can't one work without the other? This website has been created for this very purpose, to guide you to your air-conditioning needs.

    Cleaning your air conditioning filter will ensure an allergy-free, healthier and more breathable environment and a properly functioning air conditioning system. It is important to clean your air conditioning filter on a monthly or bi-monthly basis to ensure your air conditioning unit is working to its capacity. Especially in hot zones of the United States, such as Miami and Tampa, where you would be using the air conditioning on a daily basis. Replacing an old air conditioning filter may be necessary, especially if you are moving into a newly renovated home. Occasionally, cleaning your ductwork can also provide a more efficient air conditioning unit. If the ductwork is too clogged with dust and debris, an air conditioning company or air conditioning contractor needs to come in to clean, repair and install any air conditioning parts. This should also be part of the air conditioning company's annual inspection.
    Air conditioning installation should be based on the customer's needs and the size of the property. A creditable air conditioning company will also come in annually for a routine inspection as part of its air conditioning service and do any air conditioning repairs needed for rusted evaporator coils in the air handler , the condenser coil in the condenser unit and checking the level of the air conditioning refrigerant.
    Air conditioning filter , the website, was created for the home or commercial property owner who would like to know more about the air conditioning parts in the air conditioning system . Everything you would need to know, from when to clean your air conditioning filters to why a heat pump is so important to the vitality of your air conditioning unit has been covered. A variety of clarifications for different products of air conditioning equipment has been researched and written to assist in all of your air conditioning needs. In addition to just general information, air conditioning filter, the website, offers thermostat options , the different types of air conditioning filters and much more. Everything you need to know about your air conditioning system is here - all you need to do now is to keep reading.

    York's quality components and revolutionary technology provide the highest efficiency, greater comfort and whisper-quiet operation.Seasonal PromotionsHome Comfort Products</SPAN>FinancingProduct RegistrationWarranty InformationExtended ProtectionMaintenance TipsGlossaryFAQ'sSafety BulletinsContact UsAbout UsSite MapPrintable Version What is a "Split System" Air Conditioner?
    A traditional home comfort system has two parts: an indoor unit, such as a furnace or air handler, and an outdoor unit. An air conditioner is the outdoor unit that cools air and sends it to the indoor unit to be circulated through your home. The indoor and outdoor units are designed to work together, and when the air conditioner is properly matched with a furnace or air handler, the result is maximum efficiency and extended system life. Air conditioning and cooling efficiency is measured using a Seasonal Energy Efficiency Ratio (SEER). A higher SEER signifies higher energy efficiency.

    Central Air Conditioning
    A home's "split system" central air conditioning system includes a compressor, a fan, condenser coil, evaporator coil and a refrigerant. It extracts heat from indoor air and transfers it outside, leaving the cooled indoor air to be recirculated. The efficiency of central air conditioning systems is rated using SEER ratios. A central air conditioning system uses electricity as its power source.

    The basic components of an air conditioning system are:
    • A Condensing Unit (the outdoor section)
    • A matching indoor Air Handler or Furnace with coil
    • Ductwork to transfer the cooled air throughout the home
    York offers a wide variety of central air conditioners in different styles, sizes and efficiencies.

    A split-system utilizes separate or "split" evaporator and condensing sections for the air conditioning system. The evaporator section, or air handling unit, is typically located indoors at the floor or ceiling level. Larger systems may require roof-mounting and can be designed to cool, heat, provide Type X, Y, or Z pressurization, and chemical filtration when required.
    All units may also be marked with the US and Canadian Class I/ Zone system upon request (example: Class I, Zone 2, group IIB+H2).
    CSA (C/US) Certified from 1-1/2 to 20 tons for Class I, Division 2, Groups B, C, D hazardous (Classified) locations, split-system air conditioners and heat pumps can be furnished with auxilliary blowers, motorized dampers, electric heat (in air conditioners), thermostatic controls, and many other features to satisfy customer needs in heating, cooling, humidity control, pressurization, etc. Options include stainless steel cabinets and coil coating for corrosion prevention.
    IEC Zone 2 - Split-system air handlers and condensing units can be designed for use in IEC Zone 2 hazardous areas. Although they do not bear the CE mark as required for installation in the European Union, they are intended for use in other countries that prefer the IEC methods of protection. These air conditioners are certified to conform to Zone 2 requirements by Marc Climatic Controls and all applicable Certificates of Conformity will be provided for components. These air conditioners are not for installation in North America.
