Duct air conditioners with fresh air supply from the street

If the room is air conditioned, keep doors and windows closed. Otherwise, the load on the equipment increases, and its efficiency decreases. The amount of oxygen in the room is rapidly decreasing, people begin to feel ailments: they cut their eyes, have a headache. Therefore, periodic ventilation is necessary. Air conditioners with an inflow of fresh air relieve the owners of the worries about ventilation.

Air intake from the street

Air intake from the street by the air conditioner is carried out simultaneously with cooling (heating). Therefore, fresh air is delivered at the required temperature. Some models of window air conditioners or split systems for an apartment are equipped with a mixing function. On average, a monoblock window mixes about 6 cubic meters of air per minute.

Wall-mounted air conditioners with air intake are equipped with the following components:

• air valve and filter;
• blower fan with speed controller;
• outer grill;
• heating element (for heating the air in the cold season);
• thermally insulated air duct.

To ensure air intake from the street by the air conditioner, installers conduct an additional air duct route. Therefore, the installation of such equipment is somewhat different from the usual one. Wall mounts with mixed air are still a novelty. They began to be produced several years ago and only by the largest manufacturers. The mixing function significantly increases the cost of the equipment. Some models are equipped with a function for humidifying the supply air, others automatically detect dangerous levels of carbon dioxide and start the admixture.

Duct systems with air intake

All duct air conditioners are equipped with this option. The filtered outside air, brought to a comfortable temperature, is distributed through the air duct system to the premises.

Such air conditioners are mounted hidden - air ducts and units are hidden under a false ceiling. Therefore, they do not affect the design of the premises in any way.

The average performance model of the air conditioner with air intake provides an inflow of 9 cubic meters per minute.

Cassette air conditioners with air intake

Among cassette split systems, there are models with mixed air. The most powerful of them circulate up to 30 cubic meters per minute. These air conditioners serve up to 100 square meters. Cassette splits are almost indistinguishable from wall mounts in design. But the format of the indoor unit is designed for installation in a suspended ceiling.
