HYBRID AIR CONDITIONER

This device is the perfect solution to the problems of traditional technology, and also provides 90% energy savings. Hybrid air conditioning allows to reduce energy costs at usual design.

This Hybrid Air Conditioner includes: an energy management unit that controls the distribution of energy received from thermoelectric generators. This energy is redirected to the power supply of the air conditioner itself, or power supply to the network or to external carriers.

The difference of this Hybrid Air Conditioner from standard air conditioners is the availability of elements that are able to convert heat and cold into electricity. By means of PN transition the air conditioner can generate electricity during transmitting the recycled heat and cold through itself. The temperature difference (Δt) is formed between the sides of the thermoelectric generator and can vary depending on the external air temperature, an average of 40-50 degrees. According to this principle the thermoelectric generator is capable of producing a direct current. The thermoelectric generator is added to the air conditioner design, as well as the converter, the network inverter and the air conditioning control system.

Elements of the thermoelectric generator are located on three heat exchangers (recuperators) and will be connected in series, which will ensure the summation of the power of each element. After that, the received energy goes to the converter, which converts the DC voltage into the voltage required for the network inverter. A network inverter will divide and redirect the received energy from the network and the energy from the elements. All information about the amount of electricity generated by the air conditioner, and, consequently, about the economy of the consumer will be displayed on the control panel display.

The Hybrid Air Conditioner is designed, patented and tested by the technology of Infinity SAV company in 2015

Hybrid Air Conditioner is designed to create comfortable microclimate conditions in use in household, industrial and administrative premises, mobile objects, at technological processes.

This Hybrid Air Conditioner consumes much less electricity from the network in comparison with the existing air conditioning systems. Air conditioning is carried out according to the following scheme: conditioned air (with or without the addition of outdoor air) – fan – air filtration – air heating (cooling) – air supply to the room.

The most energy-intensive operations in the air conditioning process are air heating or cooling. Each of these operations requires the use of special expensive equipment.

Air cooling is a particularly relevant way of air conditioning. In most air conditioning methods, a method of cooling air with refrigerants (ammonia, freons, hydrogen, nitrogen, etc.) with a low boiling point is used. As a rule, during the cooling of the room, it is necessary to continuously utilize the residual amount of heat. Modern air conditioning systems take heat outside the premises.

Comparative characteristics

Consumption schedule of electricity of conventional conditioner and Hybrid Air Conditioner

This graph shows that under the same conditions, a conventional air conditioner starts consuming electricity and spends, during the whole operating time, 2-2.5 kW/h. In ten hours consumption will amount to 25 kW of electricity.

The Hybrid Air Conditioner starts with the same consumption, but within 5-10 minutes after the start of operation, the power consumption is reduced to a minimum from 0.25 kW/h to 0.1 kW/h. This is ten times less than the consumption of known air conditioners, and in the same 10 hours will spend only 1-2.5 kW. Hybrid Air Conditioner will create exactly the same amount of cold as the usual air conditioner.

The main working blocks of the Hybrid Air Conditioner

Rotary compressor

Two highly efficient independent compressors are used to operate the Hybrid Air Conditioner. Compressors work parallel to each other, it allows to get a large difference of temperature delta that gives high efficiency in the process of energy recovery.  One compressor works with freon, allowing it to circulate through copper tubes. This makes it possible to transfer the constant heat to the connected power generating elements. The second compressor works with water, which circulates through parallel pipelines, allowing to compensate for the overheated system. The second side of the cooled compressor is used to cool the room with radiators.

Innovative inverter

Inverter allows to reach the set temperature mode 2 times faster than the non-inverted model. The absence of large inrush currents when the compressor is switched on reduces the load on the electrical network.
Inverter has the function of “mixing” the received energy with the energy from the network, under control of the control system.
The accumulated energy is supplied to the inverter from three heat exchangers (recuperators) in the form of a direct current. The inverter feeds the air conditioner system and maintains its constant operability. The excess energy is converted to AC 220V / 60Hz to return back to the network.

Generator of electricity

Thermoelectric generator is a technical device (electric generator) intended for direct conversion of thermal energy into electricity by using thermoelements (thermoelectric materials) in its construction.
Heat transfer occurs through thermal paste.

Blocks of recuperators

Water block

Cold water enters the water recuperation block. Water passes through a copper coil and electric generators produce electricity.
After passing through the block, the water goes to discharge.

Freon block

The superheated freon enters the Freon block to further transform the heat into electricity using thermoelectric generators.

The air block

Cold freon enters the air recuperator unit.
Due to circulation of Freon, copper radiators are cooled rapidly. Cooled air enters the room with a fan.
