In one aspect, a cooling tower system is provided that includes an evaporative heat exchanger, a sensor configured to detect a parameter of evaporative liquid distributed onto the evaporative heat exchanger, and an evaporative liquid treatment system. The cooling tower system further includes a controller having a normal operating mode wherein the controller operates the evaporative liquid treatment system to treat the evaporative liquid upon a determination of inadequate evaporative liquid quality based at least in part on the parameter of the evaporative liquid. The controller has a failsafe operating mode wherein the controller changes operation of the cooling tower upon a determination that the operation of the evaporative liquid treatment system is unable to remedy the inadequate evaporative liquid quality.

A heat and mass transfer system configured to be a passive system using gravitational force to form a thin liquid film flow on an outer surface of a flow distribution head and downstream conduit member to subject the thin liquid film to heat transfer mediums. The at least partially spherical flow distribution head creates a uniform thin flow of liquid on the outer surface increasing the efficiency of the heat and mass transfer system. The heat and mass transfer system may include a heat transfer medium supply system in fluid communication with internal aspects of the downstream conduit such that a heat transfer medium flows within the downstream conduit while the liquid film flows on the outer surface of the downstream conduit. Rather than conventional sheet flow on inner surfaces of a conduit, the flow distribution head enables sheet flow to be formed on an outside surface of a component.

Embodiments of a direct-drive fan system and a variable process control system are disclosed herein. The direct-drive fan system and the variable process control system efficiently manage the operation of fans in a cooling system such as a wet-cooling tower or air-cooled heat exchanger (ACHE), HVAC systems, mechanical towers or chiller systems.

A hybrid heat pump system comprising a heat pump loop integrated with a hydronic loop. The hybrid heat pump system offers multiple modes of operation to provide increased versatility and improved performance. Each of the loops can operate independently. In addition, the loops can operate in conjunction with each other in both heating and cooling modes. Still further, the hydronic loop can provide a reheat function when the heat pump loop is operating in the cooling mode to provide improved dehumidification of the air delivered to the conditioned space. The heat pump loop may include a hot gas bypass functionality for capacity control and/or freeze protection. The hydronic heat exchanger and the space heat exchanger of the heat pump loop may be combined in a compact single slab construction with a slit fin preventing cross-conduction between the heat exchanger sections.
