AC is installed in almost all humid and warm places and has become the necessity for every home. But we need heating mechanism in certain geographic locations. We tend do research a lot before investing on anything. AC is almost like a lifetime investment as we don’t change it every now and then. Do compare prices, capabilities from different manufacturers, see reviews online and do check the prices online – if you are lucky you will be get the AC for a good discount. Special occasions like Christmas and New Year will have showrooms run huge discounts.

Reverse AC: Reverse cycle air conditioner, the condenser, which expels unwanted heat, is also located in the inside unit. The two units are connected by insulated tubes, which are typically piped through a small hole in the wall. Depending on your location and the climatic conditions you will have to choose one that best suits you.

How does the reverse AC work?

 

Reverse cycle air conditioning extracts heat from the outside air, even on mid-winter nights, and transfers it inside. A refrigerant is passed through an external coil, absorbing heat from the outside air. This refrigerant is then pumped through a compressor into a fan coil unit (or ‘condenser’) inside the home, releasing its heat into the room. By reversing the flow of this refrigerant, reverse cycle air conditioners also provide efficient refrigerate cooling in summer.

 

Comparison with direct electric heaters

 

Most electric heaters create heat directly, using elements which heat up when an electric current passes through them. These ‘direct element’ heaters include portable heaters, panel convectors and off-peak storage heaters. They have a maximum efficiency of 100%, when all the electricity is converted to heat and delivered to the room. Up to three or more units of heat can be transferred for every unit of electricity used to run reverse cycle air conditioning. Therefore, running costs can be as low as one-third of those for direct element heaters. They are expensive to invest but beneficial in the long run.

 

Advantages of reverse AC

 

It can be used for both cooling and heating.
It has no exposed elements and can be touched anytime as it doesn’t get heated up.
It has a long lifetime of over 20 years.
It filters and dehumidifies air.
This is suitable for people who move frequently from place to place.

 

Types of reverse AC:

 

Portable: Portable units can be moved from room to room or house to house.  They are connected to standard power points. External units are usually hung outside an open window. 

Wall units: have all their components together in one unit, which is permanently mounted through an external wall or window. Curtains must be left open during operation if installed in a window. It may be noisy as it is motor operated.

 

Power consumption:

 

AC is known to increase the power consumption. For residential homes, some countries set minimum requirements for energy efficiency. In the United States, the efficiency of air conditioners is often (but not always) rated by the seasonal energy efficiency ratio (SEER). The higher the SEER rating, the more energy efficient is the air conditioner. So be sure before you purchase air condition.

Refrigerants used in AC units are chemical based and must not be released carelessly into the atmosphere. An expert HVAC service technician will know the details and it’s wise to hire them to be safe and to keep our environment safe.
