Abstract
A variable capacity chiller or hydronic heat pump with a compressor, a pump, and a condenser fan where system capacity is controlled by the speed of the compressor, pump, and/or condenser fan based on the flow rate and ΔT between the returning water temperature and leaving water temperature, where the compressor, pump, and fan adjust automatically to match the changing load conditions to match the capacity to the load, and which includes a psychrometric climate controller that manages a chiller or chiller heat pump to heat or cool a heat transfer fluid in communication with indoor heat exchanger(s) and where the setting for the entering or leaving heat transfer fluid temperature can be automatically varied based on psychrometric data or on information derived from such sensors, and when in heating mode, to dynamically manage an external backup resistance heat source to accurately match any shortfall of heating capacity.
