SORKE s.r.o. Pardubice specialises in the air-conditioning branch, for the improvement of the interior environment in buildings and technologies. We provide technical proposals and deliveries for ventilation, energy recovery, warm-air heating, air-conditioning and cooling. 
Space Heating
The principle of a solution where warm air is supplied to the building and heats the premises and/or air circulates and is warmed up in a hot-air unit. If the hot-air heating has been installed in the building, it does not have to be a kind of forced supply of fresh air in the heated premises. This may be achieved with ventilation technology and hot-air units fitted with a mixing chamber through which outer air is sucked in are used in most cases for this purpose.
Systems with fully circulating operation belong to standard hot-air heating systems. Distribution of heating air to individual premises within the building is connected to the hot-air heater. Circulating air is sucked back into a corridor in most cases, air flow between residential rooms and the corridor is ensured through untight places around doors or through ventilation grids.

Heating and ventilation within one system
)
Operational premises may be heated with hot air distributed together with ventilation. The method is based on ventilation units consisting of a mixing, filtration or also free chambers so that it is possible to install a cooler or a fan and heating chamber later. The mixing chamber enables fresh air to be sucked from the outside and air circulation to be controlled automatically for the heating mode of the equipment in the hall. In the winter period, air is heated by means of a gas burner in the combustion chamber. Treated air is supplied through the duct fixed to the supporting construction of the building.
The air is distributed by means of whirling anemostats with automatic air flow control for the summer or winter period. The ventilation system is completed with closing pressure flaps in the outer walls of the hall with automatic control of stale air exhaust.
Hot air heating for residential purposes
)
Balanced ventilation with circulation heating of a residential building is used in the heating season when occupied. Air for heating and ventilation is heated up in the hot-water exchanger of the unit and is supplied to the residential rooms. Circulation air is exhausted centrally. In addition to circulation, air is exhausted from toilets, bathrooms and kitchens. The ventilation unit consists of a heat recovery exchanger, exhaust and supply fan, mixing section and filter. Fresh air is supplied through the outer wall of the building.
Air is treated in the unit and supplied though floor channels to individual rooms. Manually controlled floor grids ensure air distribution. The gaps under the doors enable air flow.
