A condenser is a device that is used to liquefy gas by cooling it. In HVAC equipment, hot discharge gas (refrigerant vapor) from the compressor enters the condenser coils at the top and is condensed, drains out of the condenser to a receiver located near the bottom. The condenser coil is located along with the compressor and controlling devices in the condensing unit. In a remote or split system air conditioning installation, the condensing unit is located outdoors. Condensers are available in a variety of sizes and designs that include plain tube, finned tube and plate type, series-pass and parallel pass units.Condensers are classified by their cooling method. The three main types are broken down to: Air-cooled condensers Combined air and water-cooled condensers Water-cooled condensers Air-Cooled CondensersAn air-cooled condenser consists of a coil of ample surface that air is blown by a fan or induced by natural draft. This type of condenser is universally used in small capacity refrigerating units. Mostly designed for residential or small office air conditioners.Air-chilled condensers should be kept from free from dirt, lint and other foreign materials because they tend to reduce the airflow around the tubes and fins if they are allowed to accumulate just like evaporators.Combined Air- and Water-cooled CondensersThis type of condenser is also know as an evaporative condenser and consists of a coil cooled by water sprayed from above and then cold air enters from the bottom and is blown across the coils. As water evaporates from the coil it creates a cooling effect that condenses the refrigerant within the coil. The refrigerant gas in the coil is hot which changed to the liquid state by combining the sprayed water and the large column of moving air supplied by the fan. The water that does not evaporate is recirculated by means of a pump.Water-Cooled CondensersA water-cooled condenser is similar to a steam surface condenser in that cooling is accomplished by water alone that circulates through tubes or coils enclosed in a shell. IN a water-cooled condenser the refrigerant circulates through the annular space between the tubes or coils. Because of its construction, a water-cooled condenser is also referred to as a double-pipe condenser. Because an evaporative condenser is not wasteful of water, large compressor installations are possible in areas where water is scarce. Tests have shown that the amount of water required will not exceed the.03 gpm per ton of refrigeration. This is one of the eco-friendly reasons to use this type of condenser. Evaporative condensers also eliminate water water disposal problems and provide the most economical means of cooling refrigerant gases of standard air conditioners.
Important Furnace Repair Tips for Your Home
An HVAC system is a large investment on your part. We're not just speaking in reference to the initial costs of purchasing and installing the equipment, but we're also referencing the amount of money you will spend on energy bills over the years. Statistics say that you will spend well over $2,000 this year on energy bills alone. Your HVAC system accounts for almost half of the energy your home consumes within that time period. Your home, no matter how old or new, is an energy hog. Whether you're choosing to upgrade your existing HVAC system or installing a new one in your new home, here are some tips you should adhere to in order to choose the proper-sized system that will ensure energy-efficiency.So what does one do to prevent your home from sucking up so much energy? First, understand that if your equipment is old, it's time to replace it. Equipment that is 10 years or older is extremely inefficient and should be replaced, preferably with an energy-efficient model (i.e. Energy Star qualified). When purchasing any type of HVAC equipment, it's smart to go with an energy-efficient model. It will save you a ton of money over the years. You're probably wondering, "So if I choose energy-efficient equipment, why does sizing matter?" It matters! Choosing the proper-sized equipment (i.e. proper heating/cooling output) directly affects your comfort, your HVAC system's efficiency and its maintenance and operating costs. You can see how important and underestimated this topic is. In fact, it has been estimated that over half of the HVAC industry does not size your HVAC systems properly."Oversizing" tends to be the biggest mistake that is made. When you oversize an HVAC system, it can affect a number of areas within the process. For example, the installation will be more expensive. Typically oversized systems tend to cost more to operate, break down often, run inefficiently and require more maintenance. Oversized air conditioners tend to shut off before they've had a chance to dehumidify the air properly. This results in a clammy environment that may be prone to mold. Oversized furnaces create uncomfortable temperature swings.When your HVAC technician attempts to size your system, they should not be reading a label or simple by-the-book standards. Instead, the calculation should be multi-variable and include factors that are unique to your situation. For example, what is the climate like in your area? How many windows do you have and what size are they? How much insulation is there and what type of insulation is it? How big is the house? Is the house two-story or one-story? How much outside are is sneaking in? How many occupants are there? There are two industry standards that should be used to help determine the proper size for your system. These are "Manual J" and "Manual D", created by the Air Conditioning Contractors of America. Manual J, also called "Residential Load Calculation", is primarily used to determine HVAC size calculations. A reputable HVAC company will tell you that they use Manual J to determine sizing. Manual D, also called "Residential Duct Design", is used to determine duct sizing. When looking for a company to help install your new HVAC system, always be sure to inquire whether or not they use Manual J and D in their sizing and installation process.
