Abstract
A controller, a water source heat pump and a computer useable medium are disclosed herein. In one embodiment the controller includes: (1) an interface configured to receive operating data and monitoring data from the water source heat pump and transmit control signals to components of thereof and (2) a processor configured to respond to the operating data or the monitoring data by operating at least one motor-operated valve of the water source heat pump via a control signal.
Claims17
A controller, comprising:
- one or more processors configured to:
- determine whether a water temperature in a condenser coil is above a first setpoint when a valve is open to a first flow setting that permits warm water to flow to the condenser coil;
- and
- communicate a first control signal, wherein content of the first control signal depends on whether the water temperature in the condenser coil is above the first setpoint when the valve is open to the first flow setting;
- wherein, in response to a determination that the water temperature in the condenser coil is above the first setpoint when the valve is open to the first flow setting, the first control signal indicates to open the valve to a second flow setting.
A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform actions comprising:
- determining whether a water temperature in a condenser coil is above a first setpoint when a valve is open to a first flow setting that permits warm water to flow to the condenser coil;
- and
- communicating a first control signal, wherein content of the first control signal depends on whether the water temperature in the condenser coil is above the first setpoint when the valve is open to the first flow setting;
- wherein, in response to determining that the water temperature in the condenser coil is above the first setpoint when the valve is open to the first flow setting, the first control signal indicates to open the valve to a second flow setting.
A Heating, Ventilation, and Air Conditioning (HVAC) system, the HVAC system comprising:
- a water-cooled condenser comprising a condenser coil;
- a valve configured to permit warm water to flow from a stored water system to the condenser coil when the valve is open;
- and
- a controller configured to:
- determine whether a water temperature in a condenser coil is above a first setpoint when a valve is open to a first flow setting that permits warm water to flow to the condenser coil;
- and
- communicate a first control signal, wherein content of the first control signal depends on whether the water temperature in the condenser coil is above the first setpoint when the valve is open to the first flow setting;
- wherein, in response to a determination that the water temperature in the condenser coil is above the first setpoint when the valve is open to the first flow setting, the first control signal indicates to open the valve to a second flow setting.
