High latent circuit with heat recovery device

摘要

A conventional air conditioning system has a heat recovery device installed therein such that the return air from the space is passed through a heat gaining portion thereof and the resupply air passes through a heat rejection portion thereof. Substantially 100% outside air is passed through the heat rejection portion thereof where it is cooled prior to passing through the evaporator coil (14) and to the space to be cooled. After the return air is passed through the heat gaining portion, it is passed through the condenser coil (12) and then discharged outside. A subcooler is preferably provided downstream of the evaporator coil (12), and an evaporative cooler is preferably placed upstream of the heat gaining portion of the heat recovery device (26) to provide substantially improved cooling and dehumidification characteristics.
