Series circuit is closely related to a series of control applied in refrigeration and ventilation systems.<\/span> The control circuit is an electrical circuit that can control the electrical load in a system.<\/span> If all the control devices are connected in series, then opening a contact switch or other control device that is in the circuit will open the circuit and stop the distribution of electrical current or electrical loading.<\/span><\/p>\n 3:30 image shows an example application of series-parallel circuit that applied to domestic refrijerator.<\/span> A combination of series and parallel circuits are used on electrical systems equipment refrijerator system that serves to keep the temperature as desired.<\/span> Control devices connected in series with the equipment being controlled, namely an electric motor.<\/span> The circuit protection device series also includes a system necessary to maintain the security of the operation of a component equipment.<\/span><\/p>\n Where it will stop the operation of the compressor in case of unsafe operating conditions.<\/span> If there is a contact of a safety device opens, the compressor will open the electrical circuit and the compressor will stop working.<\/span><\/p>\n
