Abstract
A cooling system for charging and discharging fluid is disclosed. The system includes a main fluid circuit and a secondary fluid circuit. The secondary fluid circuit includes: a receiver configured to receive and discharge fluid flowing through the main fluid circuit and the secondary fluid circuit; a pump configured to communicate with the receiver; a receiving valve selectively open to direct fluid to the receiver; and a returning valve selectively open to discharge fluid from the receiver. The system further includes a controller communicating with the main fluid fircuit and the secondary fluid circuit and a sensor detecting sensing value within the cooling system.
Claims20
A cooling system for charging and discharging fluid, the cooling system comprising:
- a main fluid circuit;
- a secondary fluid circuit comprising:
- a receiver configured to receive and discharge fluid flowing through the main fluid circuit and the secondary fluid circuit;
- a pump configured to communicate with the receiver;
- a receiving valve selectively open to direct fluid to the receiver;
- and
- a returning valve selectively open to discharge fluid from the receiver;
- a controller configured to communicate with the main fluid circuit and the secondary fluid circuit;
- and
- a sensor configured to detect a sensing value within the cooling system and to communicate with the controller.
A method of controlling fluid flow of a cooling system, the method comprising steps of:
- detecting, by a sensor, a sensing value;
- determining, by a controller, whether there is a fluid leak based on the sensing value;
- upon determining there is no leak, operating the cooling system in a steady state;
- measuring, by the sensor, a subcooling value;
- determining whether the subcooling value is within a threshold;
- upon determining the subcooling value is outside the threshold, controlling a receiving valve to open and a returning valve to close to direct fluid flowing from a condenser to a receiver;
- waiting for a predetermined period of time;
- and
- repeating the steps.
