Abstract

PURPOSE: To automatically compensate minimum ventilating air volume in an animals shed with no window, by connecting a time, during which a ventilating fan is out of operation, to a detecting circuit.
CONSTITUTION: A platinum temperature measuring unit A, a set pointer for the greatest lower bound or raising and a relay coil L, and a high temperature avoidance set pointer for the least upper bound or raising and a relay coil H are connected to a 4-position control system thermometer B, and a series circuit of a constant opening thermostat Th and an extroadinary high temperature detecting rapid- exhuasting auxiliary relay coil CTH is connected in parallel to the thermometer B. A relay CH is turned on as a result of a contact H-1a or a CTH-1a being closed in the case of a high temperature, and operates fans at a full speed by closing all contacts of a single-windling start trap transformer. At this time, the production of arc in a transformer will be protected by a relay CL for set temperature. Contacts L-2b and H-2b are closed and a timer T works in the case of a relay L or B being out of operation, and a contact T-1a closes and a synchronous motor M runs after a set time has elapsed. Subsequently, a contact P6 is closed by a cam R, and then P1 is closed for the duration of 1 minute, P2 for the duration of 2 minutes,... P5 for the duration of 5 minutes, so that the fans can work intermittently.
