I have a Sharp heating and air conditioning system and would like to know if my air exchanger should be on at the same time! Thank you!

What is a condenser?
Is a device or unit used to condense vapor into liquid. A condenser is simply one component of an air conditioner. Whether you have an outdoor air conditioner or a window unit air conditioner your air conditioner contains a condenser.
Condensers are used in outdoor air conditioning systems as well as heat pump systems. Condensers in an air conditioning unit have very few controls. They will have an on and off switch. Occasionally these air conditioners will also have a brown out option. This option shuts down the compressor when the electrical current is low.
A condenser is simply a heat exchanger. It compresses refrigerants into a hot gas to then condense them into a liquid. A condenser is a major component in a air conditioning or heat pump unit. It moves air across the coils to facilitate the transfer of heat.
In a heat pump unit the condenser has a few more features. It will have a reverse valve that allows the unit to switch back and forth between air conditioning and heating. Even when the unit is heating, it uses the condenser for defrosting the coils. If the coils become layered with frost it will effect the units effectiveness this is defrosted when the reverse valve switches to air conditioning mode to move the hot gases through the coils melting the built up ice. It will automatically switch back to heating mode once the ice is cleared to once again heat the home.
To keep your unit in good operating condition it is vital to keep the area around the condenser clear of all debris as well as keeping the filter clear of dust and dirt. A clean machine makes a happy machine. A happy machine will keep you cool during the summer months and warm during the cold months. It is suggested to change the units filters when they become dirty, depending on your area and conditions near your home this may be as often as once a month or as seldom as every 3 to 6 months. You will have to pay close attention to your units needs to decide the right time to change or clean your unit’s filters.
It is very important no matter what type of unit you have to prevent the blockage of the condenser. If the condenser becomes block it can effect the units efficiency or even cause the until to completely fail. For this reason it is one of the most important components of a cooling or heating system. A condenser allows the maximum airflow to the unit.
Keeping you condenser in good running condition will not only prolong the life of your heat or cooling system but also provide you with the most efficient heat and cooling system saving you money on heat and cooling.www.victorwod1234.blogspot.com

An air-to-air exchanger is used to recover heating or cooling and to improve the air quality of the building that it serves. Typically an air exchanger has two fans, one blowing air into the house and one blowing air out of the house. In the winter time the one fan brings the outdoor cool air through the core warming it with the warm stale air you are exhausting. In the summer time the warm air from the outside will be cooled as it enters through the core to save on your cooling.

Air exchangers often are used to perform many functions such as reducing air contamination, heating or cooling air entering the building, and humidifying or dehumidifying air before it enters the building. Air to air heat exchangers or heat recovery ventilators, are used to provide a balanced flow of air into and out of a building. Ultimately an air exchangers main function is to switch the stale inside air with fresh outside air while exchanging the heat or cool in the process.

There is some controversy about the savings of exchangers. Not only does it require electricity to run the air exchanger, but the air the exchanger brings into your house must be brought up to temperature. This may require that more electric is used to cool your building or that more fuel is also required for heating.

The amount of air that these air exchangers bring into a home may vary depending on how the system has been installed. The codes in many places require a minimum amount of air to be exchanged. Check with your codes official to see what the requirements are for you.

Air exchangers can be a very good thing for many buildings. Especially those that are very large and typically have a lot of occupants with little natural air exchange from doors or windows being opened. However they are also a health hazard if they are not serviced

All air heat exchangers will require regular maintenance. The problem is that this is almost never performed by homeowners, and unless they know about the exchanger it is often overlooked by contractors during service calls. The real problem is that clogged, air-to-air exchangers can make the indoor air significantly worse than it would be without the system installed at all. If you have a home that already has a heat air exchanger, make sure that you keep it very well maintained or disconnect it.

Many air exchangers are controlled simply by on and off switches, but in some applications where the removal of humidity is required, then a humidistat can be used to turn the machine on and off to achieve the humidity level that you want. In cases where there may be a lot of humidity the air exchanger may not be enough to solve the problem. Other devices may be needed to lower the humidity to the level that you want.
