Abstract

PURPOSE: To reduce the cost of the operating circuit by providing the contact point of a temperature regulator which detects the cycle temperature of the refrigeration cycle to be started first in series with the magnetic switch for the compressor of the refrigeration cycle to be started next.
CONSTITUTION: A contact 13 of a temperature regulator which detects the cycle temperature of the refrigeration cycle to be started first is provided in series with a magnetic switch 10 for the compressor of the refrigeration cycle to be started next to have it started after detecting the cycle temperature of the first refrigeration cycle thereby eliminating the need for an expensive timer relay to reduce the cost of the operating circuit.
