Abstract

Ventilation system for the ventilation of service rooms, where the microclimate requirements are not demanding, characterized in that, in order to intensify the heat exchanges, the cold duct (5) is enclosed by five sides with hot ducts connected to each other.

Description

It is an air conditioner for the natural fanless ventilation of the operating rooms, where the micro-climate requirements are not demanding, known (patent SU N1295161 A1 Class F24F / 08 of 08.11.1986), which has been tested with good results.

• – die Fläche des Wärmeaustausches zwischen den erwärmten und kalten Luftströmen ist zu klein;
• – für die Zuerwärmung der Zuluft wird ein elektrischer heißer glattflächiger Erwärmer benutzt, der sehr große Temperatur (bis zu 500°C) leisten kann, was zu Brandgefahr führen könnte und vom hygienischen und sanitären Standpunkten unangenehm ist;
• – der Winddruck wird für die Zuluftbewegung nicht benutzt;
• – die Anlage hat keinen Temperaturregler.

But this air conditioner has the following disadvantages:

• - The area of heat exchange between the heated and cold air flows is too small;
• - For heating the supply air, an electric hot smooth surface heater is used, which can afford very high temperature (up to 500 ° C), which could lead to fire hazard and is unpleasant from hygienic and sanitary points of view;
• - the wind pressure is not used for the supply air movement;
• - The system has no temperature controller.

• – der Kanal der kalten Luft von fünf Seiten gemeinsame Zwischenwände mit heißen Kanälen hat, die miteinander verbunden sind;
• – für Zuerwärmer der Zuluft in der Anlage wärmeübertragene Rippenröhren benutzt werden, die von Elektroerwärmern gespeist und mit Regelblock geregelt sind;
• – der Außenluftfänger in Form eines offenen von unten ausgedehnten Trichters ausgeführt ist, und unter diesem Trichter auf einem Gelenk und auf einer Feder windleitende Platte angeordnet ist, die durch eine Transmission mit einer Klappe verbunden ist;
• – auf der Zuluftöffnung eine Klappe angeordnet ist, die durch Transmission mit thermobimetallischem Regelvorrichtung verbunden ist;
• – Abluftröhren mit „Düsen Venturi” ausgestattet sind;
• – Zwischen der Anlage und der Außenwand Wärmedämmstoff eingelegt ist.

These disadvantages are avoided in the proposed "ventilation system" in that:

• - the channel of cold air from five sides has common partitions with hot channels connected to each other;
• - used for heating the supply air in the system heat-transferred ribbed tubes, which are fed by electric heaters and regulated with control block;
• - The outside air trap is designed in the form of an open bottom-extended funnel, and is arranged below this funnel on a hinge and on a spring wind-conducting plate which is connected by a transmission with a flap;
• - On the Zuluftöffnung a flap is arranged, which is connected by transmission with thermobimetallic control device;
• - Exhaust pipes are equipped with "nozzles Venturi";
• - Between the plant and the outer wall thermal insulation material is inserted.

This plant on the 1 . 2 . 3 and 4 dagestellt.

Claims (6)

Ventilation system for the ventilation of premises where the microclimate requirements are not demanding, characterized in that, in order to intensify heat exchanges, the cold channel ( 5 ) of five pages with hot channels that are connected to each other is included. Ventilation plant according to claim 1, characterized in that in the system heat-transmitting ribbed tubes ( 18 ), which are powered by electric heaters and regulated with control block, together with diagonal fan ( 15 ) to avoid fire hazards and to provide improved air condition. Ventilation system according to one of the preceding claims, characterized in that outside air scavengers ( 3 ) is carried out in the form of an open funnel, which extends from below, and under which the wind-guiding plate (on a joint and a spring) ( 1 ), connected to a flap ( 2 ) is arranged to effectively use the wind pressure. Ventilation system according to one of the preceding claims, characterized in that on the supply air opening ( 12 ) a control flap ( 13 ) arranged with a thermobimetallic control device ( 14 ) is connected to make the system controllable. Ventilation system according to one of the preceding claims, characterized in that the exhaust pipe ( 6 ) with "nozzles Vnturi" ( 7 U.N 10 ) are equipped to intetsiv the exhaust air movement. Ventilation system according to one of the preceding claims, characterized in that between the outer wall and the system of the thermal insulation material ( 29 ) is inserted to avoid the heat losses.
