Description

The invention relates to ventilation and air conditioning.

The aim of the invention is to intensify heat and mass transfer.

The invention is illustrated in the drawings, in which FIG. 1 schematically shows the proposed device; in Fig.2 and 3 is a section A-A in Fig.1 (various versions).

The device for heat and humidity air treatment comprises a housing 1 with a pallet 2 and an irrigator 3 installed along the air flow, a fan 4 and a heat exchanger 5 in the form of horizontal pipes 6 with transverse ribs 7. The planes of the ribs 7 of the heat exchanger 5 are angled to the air flow direction.

The heat exchanger 5 is equipped with partitions 8 dividing it vertically into sections 9. The edges of the rear, along the air path, pgH EgorSAok 8 are made in the form of a cblgg - - - - - - - - L - - - - - (- V - - - - LicM with /; with I j. W 11. iw opc with -u; oi and lU

up to the next section 9, starting from the bottom, is located in the course of displacement

air relative to the previous section 9. Sprinkler 3 is also equipped with nozzles 11.

 The device for heat treatment of air works as follows.

The air transported by the fan 4 with the water droplets sprayed by the nozzle 11 flows to sections 9 of the heat exchanger 5. The passage in the intersection spaces of the heat exchanger 5, the air flow changes its direction due to the location of the fins 7 at an angle to the air flow. Separating on ribs 7, water flows inside each section 9 onto partitions 8 and is carried to the drop-makers 10. From the drop-forming agents 10, water flows into the sump 2 in the form of a multi-layer rain curtain with non-intersecting trajectories of the drops.

tact in a multi-layer rain curtain. If necessary, the increase in temperature of the air flow through the pipes 6 of the heat exchanger 5 passes the appropriate coolant.

Installing the fins 7 of the pipes 6 at an angle to the direction of air flow, partitioning the heat exchanger 5 in height, and forming a multi-layer rain curtain with the help of drop-forming agents 10 make it possible to create a device for economical heat and moisture treatment of air.

The device operates at low speeds, there is no finely dispersed water fraction, water flows from the walls of the VIS film using the drop-forming agents with 10 large drops that cannot carry the air flow — it flows multi-layer into the sump 2.

The presence of a multi-layer rain curtain additionally develops the contact surface of water and air.
