Description

The invention relates to a programmed air-conditioning switchgear intended for the automatic control of an air-conditioning process during fattening of animals in dependence on their live weight.

The known feeding devices in animal breeding and farming facilities are usually controlled by means of individual switching elements or even semi-automatically coupled. These systems and circuits maintain a specified and set temperature and air exchange according to individual control regardless of the actual and necessary air and heat consumption given by the fattening cycle mode. The disadvantage of existing air-conditioning systems is considerable consumption of electric and thermal energy and its wasteful use. Leim _D deficiency can also adversely affect the most efficient weight gain fed animals.

These previous drawbacks are eliminated by a programmed air-conditioning switchboard designed for automatic control of the air-conditioning process during fattening of animals according to their increments of their live weight, consisting of a controlled air-conditioning system with air-conditioning by several dozen fans. It is based on the fact that the fans are connected to a programmically controlled voltage source, whose input terminals are connected to mutually identical relay circuits, each consisting of an auxiliary relay and a memory rrlé, which is connected by a β programmer connected to the voltage node and via a timing circuit and a timer with a main switch;

The 18S S8S voltage earthing is connected via the first changeover contact and its summer mode, transistor relay, and the central heating relay valve's limit switch relay contacts, and the second touches of the memory relay with auxiliary relay winding and through its third touches with a common node connected the first contacts of the auxiliary relay and the first contacts of the memory relay with the terminal for the winter operation of the first switching contact of the transistor relay, while the common node is connected via the contacts of the second auxiliary relay to the pair of timing relays; touches of memory and auxiliary relay with either the first or second input terminal of the programmed power supply, the third input connected through the fourth switch contact of the memory relay, and the second touch terminal of the thirteenth relay contacts *

The main advantage of the programmed air conditioning switchboard is that during the cyclic fattening of the animals it exchanges air according to the set program and replenishes the temperature in the object depending on the increment of live weight of animals in kilograms and maintains optimal climate conditions necessary

The invention will be explained in more detail with reference to an example of wiring of a programmed air-conditioning switchboard.

The air-conditioning program switchboard is the main purpose for automatic control of the air-conditioning process. For the sake of clarity, only the circuit elements whose combination brings a new effect and are essential to illustrate the invention are shown.

The circuitry consists of a program-controlled source 12 of a graduated level, for example 60, 75,

90, 110, 220 volts.

KpKg thermometers ·

The program A / C switchboard operates as follows:

keeps the temperature of the object so that in the set time, for example after a minute, it changes the temperature with two adjustable contact thermometers K ^, Kg, from that. one for the lower temperature limit and the other for the upper temperature limit. When the upper temperature limit of the thermometer Kj is reached, the servo valve limit switch relay KS closes the central heating for a set time only. When the temperature is below the lower limit with the thermometer * 2 », the servo valve limit switch KS relay opens the central heating for the set pin only. When the object temperature is optimal, it is as specified in the program, the KS valve switch of the servo valve is stationary at rest. The amount of air depends on the number of revolutions of the fans 22 and the duration of their blowing and rest. The speed of the fans 15 is determined by the respective relay circuit 10 · 10 ... 10 _ρ and the program-controlled power supply 12 which has a step voltage of 60.75, 110.220 Volts. The blower duration 15 is programmed so that they are always 1 minute at rest and 3 minutes at rest and in program power rating of 1/4, 1/3, 1/2, 2/3, 3/4, 4/4

In the first week of fattening and air exchange does not perform. After reading the first seven days, the porn of the timer 17, which switches once every 24 hours, turns on the timer circuit 16 and starts the programmer 14. For this purpose, for example, a simple mechanical system can be used which aesthetizes the geared electric drive with the screw. and a nut that moves one day by the pitch of the screw. The matrix switches in the set switch interval, which actuates the memory relay 1RP ... nRP.

Instead of the mechanical programmer 14, it is possible to use a programmer supplied with the programmable washing machines. As already mentioned at the beginning of this paragraph, the programmer 21 will connect the memory relay 1RP from the voltage node T jda after 7 days with current 11¾ of the transistor relay RK. and its Z terminal for winter operation. The transistor relay RK is controlled by adjustable contact thermometers Kp Kg ^and determines the winter and summer operation of the device. From terminal Z closed by touching HP ^ of memory relay 1RP through first contact 1¾ of auxiliary relay R, touch PP ^ of second auxiliary relay P and pair of time relays Cj set to 1/4 power and then through 13¾ contacts. lHPj. lRg and the first input terminal are overruled

199 385 the programmable source 12 actuates the fans 15 for a period of 1 minute β for a 3 minute break. That is, the fans 15 run at 60 volts for one minute β and stand still for three minutes. After a week, the programmer 14 switches the IBP memory relays in sequence. which in turn switch the respective relay circuit 10?,? 10 _n . whose function is identical to that described in this paragraph, except that the programmable power supply 12 switches fans lg ee by increasing ee by 1/3, 1/2, 2/3, 3/4,

4/4.

In winter, at an elevated temperature inside the building and an increase in heating consumption, the current through the KSS relays KS of the central heating limit switch relay goes through the second contacts 1Po. The current flows through the common node A ', previously preceded by the above-described oest, to a program-controlled power supply 12 which then switches the fans 15. This increases the air exchange and the air one week ahead.

In summer, when the temperature reaches the set outdoor temperature, transistor relay RK closes the first touches ÍRX ^ ... ηΒΧχ to terminal L of summer operation. Current from voltage node

According to the program, the contacts of the lRPo ... nRPo of the memory relay 1HP ... nHP and then, as described above, to the program-controlled power supply 12, which switches the fans 12 again. This connection allows double air exchange in the summer months.
