Extended monitoring of a dual core energy recovery system in the arctic for proven performance and resiliency
Conventional single core heat/energy recovery ventilators (HRVs/ERVs) installed in the North are plagued with problems and require defrost strategy or frost protection for operation. Frequent defrost cycles could lead to under-ventilated homes and frost protection by a pre-heating system (electric o...

| Summary: | Conventional single core heat/energy recovery ventilators (HRVs/ERVs) installed in the North are plagued with problems and require defrost strategy or frost protection for operation. Frequent defrost cycles could lead to under-ventilated homes and frost protection by a pre-heating system (electric or hydronic) could undermine their efficiency and add to the energy cost. This paper presents results from an extended monitoring of a novel dual core energy recovery ventilation system of a triplex unit on the Canadian High Arctic Research Station (CHARS) campus in Cambridge Bay (Nunavut). The monitoring carried out over three heating seasons provided evidence about its long-term performance and resiliency, with proven continuous ventilation, withstanding outdoor temperatures below − 40℃ without frost protection and achieving high sensible effectiveness around 50% in summer and up to 90% in winter. Results presented in this paper are limited to the period of June 2018 to May 2019. Peer reviewed: Yes NRC publication: Yes |
