  • Secondary fluid valve and system
    Patent number: 10030900
    Abstract: A device, method and system is provided for regulating an ambient condition of a space via a heat exchanger that transfers heat energy from a secondary fluid to a primary fluid, and a flow control valve in fluid communication with the heat exchanger to vary a flow of the secondary fluid through the heat exchanger to provide a continuous flow of the secondary fluid between a minimum flow rate and a maximum flow rate. While in a first mode for regulating the ambient condition of the space, the flow control valve is modulated so as to provide variable and continuous flow of the secondary fluid through the heat exchanger to regulate the ambient condition to a desired target ambient condition. While in a pull-down mode for recovering after a defrost cycle of the heat exchanger, the flow control valve is modulated so as to provide variable and continuous flow of the secondary fluid through the heat exchanger to regulate a temperature drop of the secondary fluid across the heat exchanger.
