  • Patent number: 6347527
    Abstract: An integrated compression based heating/cooling, humidification and mid or high efficiency heat recovery ventilation system is provided. The integrated system is a centralized apparatus that offers a very efficient method for heating/cooling with more winter and summer humidity control plus offering heat recovery ventilation in a structure having a regulated indoor temperature and specific ventilation/energy recovery rate. The heating and cooling section of the apparatus would most commonly be configured as a forced air geothermal or air-to-air heat pump. The heat recovery ventilation section of the apparatus will incorporate a heat recovery chamber complete with a primary passive cross flow heat recovery core. Plus, a secondary refrigeration based high efficiency reversible energy recovery evaporator/condenser coil. The integrated system will also incorporate a humidification system designed to operate during the winter heating season.
