Split system with humidification and air purification: when it is needed and where it is used

Conventional air conditioning technology manages to maintain the desired room temperature, but does not control other environmental parameters. The split system with the function of humidification and air purification solves the problem in a complex way. Additional features increase the cost of air conditioners, but provide a comfortable environment in everyday life.

The use of split systems with humidification and air purification

The work of climatic technology changes the parameters of the air in the room. It's about temperature and humidity. During operation, the air conditioner evaporates water, when warm air and a cold heat exchanger come into contact, condensation occurs. The average amount of moisture removed per day into the drainage is up to 10 liters. The problem is especially relevant in winter, when central heating is on.

The normal level of humidity is 40-60%, when it falls, the well-being of people worsens.

Drying out of the mucous membrane provokes the development of viruses. Not only people suffer from a lack of moisture, but also plants and furniture.

The problem is solved by installing a household humidifier. Minus - a new device will require maintenance costs, space for placement. Buying a split system with humidification and air purification will provide favorable performance in all important parameters. The equipment has temperature and humidity sensors. Air conditioners with humidification function are installed in apartments, private houses, offices, medical institutions, hotels.

Air parameters controlled by air conditioners

The main parameters of indoor air that affect human well-being: temperature, humidity, cleanliness. The initial task of climatic technology is to provide coolness in the heat and warm up the room in the off-season. The circulation of the flow in a confined space leads to a deterioration in its sanitary and hygienic characteristics.

Expanding the capabilities of the equipment allows you to humidify the air with an air conditioner. Multi-stage filtration makes it fresh and enjoyable.

One of the ways to protect consumers is to cover the units of the indoor unit of split systems with an antibacterial composition. It processes the fan, heat exchanger and control panel.

Air humidification principle

Among the additional functions of climatic technology there is an option to increase the relative humidity. Air humidification with an air conditioner occurs in three ways:

• Equipment of a split-system with a steam generator. When water is heated by two electrodes, steam is released, which is mixed with the incoming air.
• Equipment of equipment with an ultrasonic humidifier. In a special chamber, under the action of high-frequency vibrations, a finely dispersed suspension is formed from the water. Dry air passes through the fog and is evenly saturated with moisture. The water supply in the system is replenished by condensate flowing into the drainage system. Flexible and smooth regulation of functioning is carried out by means of a built-in hydrostat.
• Using a humidifying element built into the outdoor unit. The system does not require a separate water tank that needs to be refilled periodically. The air entering the outdoor unit of the split system is passed through a zeolite cassette. The hygroscopic porous material collects condensation.With the constant rotation of the cassette, moisture is transferred to the heating section. Warm air is saturated with water droplets. The liquid supply depends on the performance of the device.

An air conditioner with a humidifier distributes it evenly throughout the room. The productivity of the equipment is 400-600 ml / hour.

Daikin research has shown that a 30% increase in humidity makes the temperature appear 1 ° higher.

Air purification principle

One of the main characteristics of climatic equipment is the quality of air purification in the manned room. The devices are equipped with filtration systems for general and special purposes. They are divided into two main categories: coarse and fine cleaning. Manufacturers of climatic equipment offer equipment with sets of different types of filters. Their purpose ranges from simply trapping dust, wool, dirt, to killing odors, bacteria and viruses.

Basic filter types

Behind the air intake grille of each air conditioner, there is a 2 µm barrier for large debris. This is a coarse filter, which is a fine-mesh plastic mesh. It protects the mechanism from contamination, which shortens the service life of the equipment. The plastic insert is reusable, once or twice a month it is taken out, washed, dried and inserted into place. Some models of air conditioners have sensors that indicate contamination of the protective mesh.

Fine filters can deal with a variety of housing contaminants:

• dust, pet hair, skin particles;
• unpleasant odors;
• pollen of plants;
• viruses, bacteria and other microorganisms;
• toxic discharge.

Installation of several types of filters improves the quality of air purification, but affects the price of equipment.

Before buying an air conditioner, choose the optimal set of functions necessary to ensure comfortable conditions in the room.

Absorption filters:

1. Coal (carbonic) - the active ingredient is activated carbon, which retains unpleasant odors and harmful particles. Requires periodic replacement.
2. HEPA filter - the translation of the abbreviation means "high efficiency particle retention". The protective barrier is formed by a system of fibers with a complex shape. The material retains particles smaller than 0.1 µm. Due to the effect of engagement and inertia, it is suitable for mechanical trapping of dust with a diameter of 0.4 µm. When the air moves, small and medium-sized particles cling to the fibers.

Antibacterial filters are made by applying an active substance to a polymer base. The components that neutralize bacteria and viruses are natural substances: catechin (extract from tea), wasabi. In budget models, the base is impregnated with vitamin C.

Photocatalytic - devices that break down hazardous pollution into harmless substances. They consist of a UV lamp and a titanium oxide coated base. Radiation kills microorganisms, and titanium is a catalyst. The filter is maintenance-free.

Plasma - a common filter option in modern air conditioner models. It works on the ionization principle. Low-temperature plasma destroys allergens and harmful particles that settle on the surface of special plates. The devices quickly remove odors from the air stream.

Electrostatic - the device creates an electromagnetic field that charges dirt particles. Having received a positive charge, they are deposited on the plates with the opposite value. Filters capture substances with a size of 0.01 microns. They are washed periodically with water.

Enzyme Biofilter contains active substances that destroy bacteria. Over time, the amount of enzymes is reduced, it is necessary to change the filter.

The first manufacturers to install a multi-stage air purification system were Samsung and Panasonic.

Modern models of Daikin, LG, Mitsubishi air conditioners are equipped with plasma filters for antibacterial treatment of premises.They trap unpleasant odors, allergens, the smallest particulate matter in exhaust gases and cigarette smoke. After passing multi-stage cleaning inside fine filters, air masses are supplied to the room. Their parameters are completely safe.

In climate systems, the filtration and humidification functions complement each other. The air flow is initially cleaned of particles from dust and allergens. Then it is passed through the humidification section (evaporator, mist suspension). At the final stage, the humidified cold stream passes through a fine filter.

The Japanese company Daikin is an innovator in air conditioning systems. It was the first to launch mass production of air conditioners with humidification function.
