Description

Connection of control unit for animal cooling equipment

Technical field

The solution concerns the connection of a control unit for an animal cooling device.

BACKGROUND OF THE INVENTION

The Kentucky Cooling System or the Florida Cooling System are most commonly used to cool animals with water in high ambient temperatures as a defense against thermal stress. The essence is the application of water to the bodies of animals - sprinkling. Subsequent evaporation of water from the body surface removes excess heat from the animal body.

The time of water application is controlled in these systems by a microprocessor with a built-in solenoid valve. The temperature sensor only activates water application when the set air temperature is reached (usually 25 ° C). The water is applied to the Kentucky system for 2.5 minutes every 7 minutes, for the Florida system 30 seconds every 5 minutes The control is central.

The disadvantage of such controlled systems is the application of water even when animals are not present in the sprayer areas. This leads to increased waterlogging of the floors and excessive use of unused water and an increase in faecal water volume. Therefore, this way of cooling management is unsuitable for stables and enclosures in the Central European climate due to the completely different construction character of the stables constructed here, compared with stables in the southern states of the USA or Israel.

SUMMARY OF THE INVENTION

These drawbacks are eliminated by the wiring controller of the animal cooling device according to the invention, which comprises a thermal comparator whose input is connected to a temperature sensor and whose output is connected to one input of the evaluation circuit, further comprising a timer to which the input is connected a motion detector and the output of which is connected via a blocker to a second input of the evaluation circuit, wherein the output of the evaluation circuit is connected to a solenoid valve control switch connected to a power supply to which the temperature comparator, timer, blocker, evaluation circuit and switch.

The wiring of the control unit according to the invention is further characterized in that the motion detector is formed by an infrared motion PIR sensor.

The wiring of the control unit according to the invention is further characterized in that the control of the solenoid valve is automatic and non-contact.

The principle of the control unit according to the invention thus consists in the individual control of the cooling process only in the presence of animals and after reaching the set activation temperature by means of thermal sensors, so-called infrared sensors. The advantage is that the water is applied in a targeted manner, i. only in the presence of an animal and thus do not result in extremely high waterlogging of the stable floors and excessive water consumption, which is very significant. At the same time, no other fecal waters are generated.

The wiring of the control unit according to the invention is based on a source. It also measures the ambient temperature and compares it to a preset temperature using a temperature comparator located inside the control unit. When the set activation temperature, as measured by the temperature sensor, is exceeded, the comparator emits a signal which is one of the conditions for triggering water in the animal cooling area.

- 1 GB 304358 B6

A second condition for the activation of the water solenoid valve is the detection of movement in the cooling space, which is provided by a motion detector, in particular an infrared motion PIR sensor. Both conditions, which are collected in the evaluation circuit, result in the solenoid valve being opened by means of a switch. The solenoid valve controls the water inlet to the cooling chamber. The water flow time can be set by a timer. At the end of the water sprinkling, this valve is blocked to prevent the water from starting again for a time selectable by the evaluation circuit after the next function has been blocked. This results in substantial water savings and more efficient use without unduly wetting the floor and creating undesirable mud and other faecal water. The advantage of connecting the control unit according to the invention is its very easy, automatic and trouble-free operation. The wiring of the control unit according to the invention is suitable for cooling animals inside buildings as well as in open-air runs and also in zoos.

The following example illustrates the embodiment of the control unit according to the invention without limiting it in any way.

Exemplary embodiment

Example 1

The wiring of the control unit according to the invention is supplied from a source 1, measures the ambient temperature and compares it to a preset value of the activation temperature by means of a temperature comparator 2 located inside the control unit. When the set activation temperature measured by the temperature sensor 3 is exceeded, the comparator 2 signals one of the opening conditions of the solenoid valve 9. The second condition for activating the solenoid valve 9 is the detection of movement in the animal cooling area. Both conditions, which are collected in the evaluation circuit 7, result in the opening of the solenoid valve 9 by means of the switch 8. The solenoid valve 9 controls the water inlet into the animal cooling area. The water flow time through the cooling space can be adjusted by means of a timer 5. After the sprinkling is complete, the solenoid valve 9 is blocked by the blocker 6 against further start-up of water for an optional time by the evaluation circuit 7. Operation of the control unit according to the invention is very simple.

Industrial applicability

The invention solves an automatic individual method of applying water to the body of animals to cool them at high ambient temperatures in order to minimize water consumption, waterlogging of floors and accumulation of wastewater in stables and open spaces.
