Abstract
A building heating and cooling system which eliminates the need for a dual circuited condenser in a water to water heat pump. The system includes a cooling tower water circuit, a device for cleaning and treating the water in the cooling tower water circuit, and a hot water circuit in the building. A single circuit condenser and a refrigerant compressor are used to heat condenser water. Apparatus is provided to inject the heated condenser water either into the hot water circuit or to the cooling tower. The heat pump also includes a cooler to provide a source of low temperature heat from a chilled water circuit in the building.
Claims3
In a heating and cooling system for a building, including a cooling tower, cooling tower water circuit means for circulating the water of said cooling tower, a heated water circuit in said building, condenser means for providing heat to said heated water circuit and compressor means operating said condenser means, the improvement comprising:
- means for cleaning and treating said cooling tower water;
- means for directly injecting said cleaned and treated cooling tower water into said heated water circuit to thereby circulate said cleaned and treated cooling tower water in the heated water circuit, thus eliminating the need for dual circulated condensers in said system and;
- bybass means for bypassing at least a portion of said water passing from said cooling tower water circuit to said heated water circuit back into said cooling tower water circuits.
