Abstract

The invention makes it possible to increase the economy by reducing the consumption of heat and water for air treatment. When the parameters of supply air deviate from the given, it is heated in the heater 1, located in front of the irrigation chamber (OK) 3, depending on the air temperature in the room, followed by moistening in the OK 3 in a linear manner depending on the temperature of the wet and dry thermometers. OK 3 with constant supply air moisture. In this case, the signal from the sensor 10 of the air tors in the room 11 is fed to the controller 6 and, at its command, the valve 2 changes the amount of heat transfer medium passing through the heater. After this, the block 7 of the regulator 6, which maintains the linear connection between the t-shorts in the dry and wet thermometers, sends to the valve 4 a signal about the change in the amount of water sprayed. 2 Il. // s (L with s 00 00 ar.

Description

This invention relates to air conditioning.

The purpose of the invention is to increase efficiency by reducing the consumption of heat and water for the treatment of air.

Figure 1 presents a diagram of the air treatment process according to the proposed method; figure 2 is a device that implements the method.

The device (FIG. 2) contains a heater 1 with a control valve 2, an irrigation chamber 3 with a control valve 4 and a pump 5, a temperature controller 6 with a linearization unit 7 and sensors 8, 9 and 10, respectively, of the temperature of the wet and dry thermometer. air temperature in room 11 and inlet fan 12

The air-conditioning method of small arms is described as follows.

At the initial moment, the treated air has a final temperature t after the heater and the temperature t and t (, on wet and dry thermometers after the irrigation chamber at a constant moisture content d const (Fig. 1). When the parameters of supply air deviate from the given, it is heated in the air heater, located in front of the irrigation chamber, depending on the air temperature in the room to a value of t, followed by moistening in the irrigation chamber in a linear manner depending on the values of temperature t and t of the wet and dry thermometers behind the irrigation Yelnia chamber to values

  with OL const.

Over the entire range of air treatment, the ratio is maintained atp + b with d const, with a and b also having constant values.

Thus, when the heat leakage into the room 11 occurs, the temperature value in the room deviates from the preset level. The signal from the sensor 10 is supplied to the controller 6 and its command is regulating

valve 2 changes the amount of heat

the carrier passing through the heater 1. In this case, the air in the first preheating heater 1 is heated to a new final temperature t instead of t (Fig. 1). After this, the block 7 of the regulator 6, which maintains a linear relationship between the temperature tj on a dry thermometer and the temperature t on a wet thermometer.

sends a signal to valve A about a change in the amount of water sprayed by changing the temperature value of the sensor 8 on a wet thermometer from tj to td,. Accordingly, the temperature of the sensor 9 according to the dry thermometer is linearly related to the value t of the temperature on the wet thermometer.

With the new change of heat leakage into the room 11, the process of adjusting the air temperature occurs similarly to that considered.
