    How to cool big home with small air conditioner(s)


    A lot of people have only one or two rooms that can take an air conditioner in the window. Often times, the air conditioner is also rated at a cooling power that would make you believe that there is no way that it can to cool the whole house/apartment. You can crank it to the max to try to cool as much as possible, but then this makes one room too cold and the others still stay too hot. You can try blasting the cool air down a hallway with a fan on maximum speed, but that only works so well. And, it's noisy, too. Well, I have two 260 sqr ft rated room air conditioners and I am cooling 2000 sqr feet of house to a comfortable 72 degrees in all rooms and it's been 95 outside all day. How to do it?

    The trick is setting up your home to take advantage of laminar air flow. Set your air conditioner to say 68 degrees and start it in the middle of the morning before it feels hot outside. Put the AC deflectors pointing downward and towards the door. Put fans in the doorways pointing out of the rooms that have the AC. Point them level to the floor (not up) and put a fan to one side near the end of long hallways. Set the fans on the lowest power setting (not high). If the hallway branches out into a bigger room, put a fan in the room that is blowing across at a right angle to the entry, pointing the air flow parallel to the wall. This will circulate the cool air around the room. Keep the fans on low and pointed parallel to the floor, not up!

    What you have created is a re-circulating air flow system, much like the North Atlantic Current that moderates the temperatures of Europe. You can check this by taking a tissue paper and holding it up to the top of the doorway. The air flow should be pushing the tissue away from the room without the AC and toward the room with the AC. This happens because the warmest air will be toward the ceiling and you want that warm air to make its way across the ceilings and back to the room with the AC, so that it can be cooled again. The cooled air from the AC will sink to the floor and the fans will gently push the air out of the room with the AC. It will stay low and travel along the floor in the opposite direction and into the warmer rooms. If you crank your fans up, you will create turbulent flow and that will not cool your house as efficiently as will laminar flow. Monitor the outside temperature and when it gets cooler outside by a few degrees, turn the AC to fan for about 10 minutes to eek out the last of the cooling. Then open the windows for the night to take advantage of the free cooling that nature provides. That's it! Enjoy the summer!

    Air Conditioning Tips & Tricks You Must Know!


    • Try setting your thermostat between 72°F and 78°F. Each degree setting below 78°F will increase your energy consumption by approximately 8%. As you can see, that can add up to a lot of money over a year.
    • Inspect and clean both the indoor and outdoor AC/Heating coils. The indoor coil in your air conditioner acts as a magnet for dust because it is constantly wetted during the cooling season. Dirt build-up on the indoor coil is the single most common cause of poor efficiency. The outdoor coil must also be checked periodically for dirt build-up and cleaned if necessary.
    • Check the refrigerant charge. The circulating fluid in your air conditioner is a special refrigerant gas that is put in when the system is installed. If the system is overcharged or undercharged with refrigerant, it will not work properly. You may need a service contractorto check the fluid and adjust it appropriately.
    • Use bath and kitchen fans sparsely when you are running the air conditioning system.
    • Reduce the cooling load by using cost-effective conservation measures. For example, effectively shade east and west windows. When possible, delay heat-generating activities, such as dishwashing or baking, until the evening on hot days.
    • Try to not use a dehumidifier at the same time your air conditioner is operating. The dehumidifier will increase the cooling load and force the air conditioner to work harder, which in turn increases your utility bill.
    • Over most of the cooling season, keep the house closed tight during the day. Don’t let in unwanted heat and humidity. If practical, ventilate at night either naturally or with fans.
    Room Air Conditioning Units
    • The unit should be level when installed, so that the inside drainage system and other mechanisms operate efficiently. If possible, install the unit in a shaded spot on your home’s north or east side. Direct sunshine on the unit’s outdoor heat exchanger decreases efficiency by as much as 10%. You can plant trees and shrubs to shade the air conditioner, but do not block the airflow.
    • Set the fan speed on high, except on very humid days. When humidity is high, set the fan speed on low for more comfort. The low speed on humid days will cool your home better and will remove more moisture from the air because of slower air movement through the cooling equipment. Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively through your home without greatly increasing electricity use.
    • Set your air conditioner’s thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be. And don’t set your thermostat at a slighter setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.
    • Don’t place lamps or televisions near your air-conditioner’s thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
    Proper maintenance of your air conditioner will also save energy. Be sure to do the following:
    • At the start of each cooling season, inspect the seal between the air conditioner and the window frame to ensure it makes contact with the unit’s metal case. Moisture can damage this seal, allowing cool air to escape from your house.
    • Check your unit’s air filter once a month and clean or replace filters as necessary. Keeping the filter clean can lower your air conditioner’s energy consumption by 5% to 15%.
    • Occasionally pass a stiff wire through the unit’s drain channels. Clogged drain channels prevent a unit from reducing humidity, and the resulting excess moisture may discolor walls or carpet.
    • *In the winter, either cover your room air conditioner or remove and store it.

    Ok So We Bought This. But We Have A Problem Does It Take Water Or Not? Thats What I Need To Know! Please Help!


    The DeLonghi PACA120E Portable Air Conditioner quickly cools rooms up to 400 square feet and comes equipped with several functions that make operation easy and low maintenance. Its 3 operating modes are supplemented with no-drip technology, an adjustable thermostat, 24-hour timer, and much more. This unit truly takes the work out of cooling medium- to large-sized spaces. Multiple Modes and Functions The DeLonghi A120E-also known as the Delonghi Pinguino PAC A120E-offers 3 operating modes and 3 additional operating functions that make this model versatile and energy efficient. Cool Mode: 12,000 BTUs of cooling power help cool large rooms, offices, or basements. Dry Mode: Reduce room humidity by removing excess moisture from the air. Fan Mode: Circulate air to keep your room comfortable without using a lot of energy. Low, medium, high, and an auto-speed are all included (auto speed selects a fan speed for you). Smart Function: Your AC uses Cool and Fan mode based on ambient room temperature. This function will also select your fan speed and keeps your room comfortable without wasting energy. Sleep Function: Using a low fan speed, the AC gradually reduces operation so your room remains comfortable but the AC runs more quietly and efficiently while you sleep. Boost Function: This function is ideal for the summer months and uses the maximum fan speed to rapidly reduce your room temperature. Useful Features Using DeLonghi's patented no-drip technology, this unit is "dripless" under normal conditions, meaning the AC will discharge all of the moisture collected from the air-so you typically won't have to worry about draining the water. When dehumidifying a lot of moisture in Dry mode, excess water may collect in the internal collection tank. Once the tank is full, the air conditioner will automatically turn off to avoid overflow damage. You can also use the included continuous drain hose as a no-fuss way to eliminate excess water as needed. An adjustable thermostat provides additional convenience by allowing you to set your room temperature. The DeLonghi portable AC will cycle on and off to eliminate over-cooling and maintain the set temperature. Additional Features Washable Air Filter: A washable air filter helps remove allergens and other particles from incoming air and saves you money on replacement filters. Quiet Operation: High efficiency compressor and components result in quiet performance. Electronic Controls: The LCD screen displays the timer and temperature settings, while intuitive indicator lights accompany each operating mode. 24-Hour Timer: This feature lets you program your AC to turn on or off up to 24 hours in advance, so it only runs when needed. Window Bracket: Double window bracket is included with purchase for flexible installation. Self-Diagnosis System: The unit includes a self-diagnostic maintenance system that identifies malfunctions should they occur. Remote Control: Use the full-featured remote control to change modes, set the timer, and select a fan speed up to 23 feet away from the receiver (on the front of the unit). Portability: Easy-roll casters and dual carrying handles make it simple to move this model from space to space.

    B zone is only cooling to 49 degrees and leds at L3 and L4 are blinking at 1 second intervals at circuit card on outdoor condensing unit. Is there a service manual available for download?


    Hi


    The L3 and L4 lights are blinking means that the filter is dirty and obstructed. You’ll need to clean the filter. Also Inspect whether the evaporator air is blocked, remove the blockage. Check the air intake and outlet ducts of the condenser side are obstructed. Check both of the ducts. Check whether the unit is set on dehumidifying mode. Set at cooling mode, Set at low fan speed Re-set the fan speed at high speed and check.

    However, if this doesn't help then it might have happened that the compressor is not runing and the connection to the compressor is cut. Please check the wiring diagram on Pg 22 in this manual---

    Comfort Aire PAC-121 problem


    E4 shows up on the screen on my PAC-121 when the water reservoir on the right-hand-side is not pushed in all the way. If it is in all the way the switch that it engages may be bad or out of place.
