Embodiment Construction

[0013]The term, “or,” as used herein, refers to a non-exclusive or, unless otherwise indicated. Also, the various embodiments described herein are not necessarily mutually exclusive, as some embodiments can be combined with one or more other embodiments to form new embodiments.

[0014]It is desirable to have an efficient and flexible method for defrosting an energy recovery ventilator unit that both minimizes the energy expended for defrosting and minimizes the time spent when the energy recovery ventilator unit is not in its normal operating mode.

[0015]FIG. 1 presents a flow diagram showing selected steps in an example method of defrosting an energy recovery ventilator unit according to the principles of the disclosure. To facilitate understanding of the flow diagram presented in FIG. 1, FIG. 2 presents a perspective view of an example energy recovery ventilator unit 200 of the disclosure, which can include but is not limited to, any of the design layouts and any of the components pa...

Abstract

A method of defrosting an energy recovery ventilator unit. The method comprises activating a defrost process of an enthalpy-exchange zone of the energy recovery ventilator unit when an air-flow blockage in the enthalpy-exchange zone coincides with a frost threshold in the ambient environment surrounding the energy recovery ventilator unit. The method also comprises terminating the defrost process, including terminating the defrost process when an operating condition in the vicinity of the enthalpy-exchange zone substantially returns to a pre-frosting operating condition.
