Abstract
The disclosure relates to an air conditioning system employing a heat pump in combination with facilities for thermal storage, evaporative cooling and solar heat collection, as well as solar heat radiation; the heat pump having an indoor heat exchanger and an outdoor heat exchanger and a third heat exchanger in series with the outdoor heat exchanger; the third heat exchanger being disposed to receive heat or cool air so as to augment operation of the heat pump during critical ambient conditions so as to improve the relative efficiency of the heat pump when operating under the aforementioned critical conditions.
Claims11
An air conditioning system comprising:
- a heat pump adapted alternately to reject heat to the ambient atmosphere and to collect heat therefrom as desired;
- duct means communicating with said heat pump and adapted alternately to deliver either cool air or heated air into a building room;
- thermal storage means communicating with said heat pump and disposed and adapted either to collect BTU's directly from said heat pump when it is delivering heat, or to be cooled by said heat pump when it is delivering cool air;
- and duct means for delivering either heat or cooling from said thermal storage means to said system when the respective demand in said room may exceed the thermal capacity of said heat pump;
- and means controlling said heat pump to either store heat in said thermal storage means or to cool it when the respective demand of said room is less than the thermal capacity of said heat pump;
- said heat pump having a first heat exchanger communicating with atmosphere outside said room;
- said heat pump having a second heat exchanger communicating with atmosphere inside said room;
- said heat pump having a third heat exchanger;
- said first and third heat exchangers having refrigerant passages which are coupled in series;
- and means for transferring heat from said thermal storage means to said third heat exchanger together with first air moving means disposed for forcing ambient air into contact with said first heat exchanger and back to atmosphere outside said room;
- second air moving means disposed for forcing air to flow into contact with said second heat exchanger and into said room;
- first duct and damper means communicating with said second air moving means and disposed to deliver air alternately from said room and said thermal storage means;
- third air moving means disposed for forcing air from said thermal storage means and into contact with said third heat exchanger;
- a roof disposed over said room;
- a solar energy collector in said roof;
- said solar energy collector having passages extending upwardly and downwardly in said roof;
- and duct and damper means adapted to provide the flow of air through said solar energy collector and through said thermal storage means and back to said solar energy collector.
