Zusammenfassung: | Process fluid from a hydronic system can be directed to an air-to-fluid heat exchanger in a heat exchange relationship with an outdoor heat exchanger of a thermal system connected to the hydronic system. The flow from the hydronic system to the air-to-fluid heat exchanger can be controlled using one or more valves. The process fluid at the air-to-fluid heat exchanger can defrost the outdoor heat exchanger, be used for free heating or cooling by being directed to a secondary load, or be used for balancing of cascade systems. A reversible fan can be provided at the outdoor heat exchanger and the air-to-fluid heat exchanger to facilitate these operations. |
