Optimal aquaculture yield is achieved when pond water temperatures range from 15–25 °C, making its practice unsuitable for harsh cold climates. To address this, a Quonset-type Greenhouse integrated Thin-film Photovoltaic (GiTPV) system is proposed, which provides a controlled environment for facilitating cold climate aquaculture. The GiTPV system is connected to an Earth Air Heat Exchanger (EAHE) utilizing shallow-depth geothermal energy for heating the enclosed greenhouse space. This study develops a periodic thermal model based on energy equilibrium equations to assess EAHE’s impact on the GiTPV system’s thermal and electrical performances. Results revealed that the EAHE with an airflow rate of 0.5 kg/s increases room air and pond water temperatures by 5 °C and 4 °C, respectively. Further, the GiTPV system generated 14.7 kWh of daily energy per day, making it self-sustainable in the real climatic conditions of the considered location.

摘要

Optimal aquaculture yield is achieved when pond water temperatures range from 15–25 °C, making its practice unsuitable for harsh cold climates. To address this, a Quonset-type Greenhouse integrated Thin-film Photovoltaic (GiTPV) system is proposed, which provides a controlled environment for facilitating cold climate aquaculture. The GiTPV system is connected to an Earth Air Heat Exchanger (EAHE) utilizing shallow-depth geothermal energy for heating the enclosed greenhouse space. This study develops a periodic thermal model based on energy equilibrium equations to assess EAHE’s impact on the GiTPV system’s thermal and electrical performances. Results revealed that the EAHE with an airflow rate of 0.5 kg/s increases room air and pond water temperatures by 5 °C and 4 °C, respectively. Further, the GiTPV system generated 14.7 kWh of daily energy per day, making it self-sustainable in the real climatic conditions of the considered location.
