TCLV ventilation units with a heat pump and heat recuperation

TCLV ventilation units with a heat pump and heat recuperation

TCLV ventilation units with a reversible heat pump and heat recuperation are designed for comfortable ventilation of residential premises in the area of commerce and services, small businesses, restaurants, educational and social institutions, sport and industrial halls where great importance is attached to energetically and financially efficient solutions.

Unit boxes are assembled from aluminium profiles. The casing is constituted by double panels made from galvanized metal sheets with thermal and acoustic insulation from mineral wool of 25 mm wide. The panels allow for easy access, control and maintenance of all internal parts including air filters and cooling circuits.

Units are equipped with energy-saving radial EC ventilators with blades turned backwards, a reversible heat pump for heating and cooling of input air, a heat recuperation exchanger, easily exchangeable filters for input and outlet air and automatic regulation.

TLCV units are compact systems with a full cooling circuit containing a working filling which consists of an ecologically harmless refrigerant and oil. Before units are ready for operation, they need to be connected to an external air-conditioning distribution, to electric network and a condensate drain needs to be connected to canalisation.

Units consist of three sections transported separately which are put together to a single aggregate during installation.

Basic operation regimes of TCLV units

  • Ventilation with heat recuperation between input and outlet air
  • Cooling of input ventilation air by means of a reversible heat pump
  • Heating of input ventilation air by means of a reversible heat pump
  • Heating of input air in extreme conditions by a heat pump by way of throttling the flow of input and outlet air
  • Heating of input air with pre-heating process conducted by an electric heater
  • Desk recuperator melting by means of an internal air circulation
  • Evaporator melting by reversing a cooling circuit

Advantages of TCLV units

  • Easy installation
  • Smooth operations in automated regime
  • Excellent technical parameters
  • High energetic effect - heat pump + heat recuperation
  • Heating and cooling of input air with minimal operation costs
  • Low consumption of electric energy - EC ventilators
