Abstract
Abstract A heat-recycling air conditioner is disclosed, which includes a first loop having a compressor, a condenser and an evaporator and a second loop having a condenser cooling water inlet and an outlet, an auxiliary heat exchanger and a source of cooling water. The cooling water flows to the condenser to absorb the heat from the coolant and then the heated cooling water flows to an auxiliary heat exchanger to add extra heat to the discharge air.

Claim 1
Independent Claim
234 words
A heat-recycling air conditioner comprising: a first loop having: a compressor; an evaporator in communication with the compressor by an inlet of the compressor; and a condenser in communication with the evaporator and an outlet of the compressor; wherein high temperature, high pressure coolant flows from the compressor to the condenser where the coolant is cooled; low temperature, high pressure coolant flows from the condenser to the evaporator; and high temperature, low pressure coolant flows from the evaporator to the compressor to be pressurized; and a second loop for condenser cooling water having: an inlet in communication with the condenser to provide cooling water to the condenser; an outlet in communication with an auxiliary heat exchanger to release heat from the cooling water absorbed in the condenser to the exhaust air; and a three-way electric valve provided between the condenser and the auxiliary heat-exchanger to control the connection between the auxiliary heat exchanger and the condenser, whereby the high temperature cooling water is able to flow to the auxiliary heat exchanger to provide extra heat to the auxiliary heat exchanger, so that the exhaust air temperature of the air conditioner is able to be kept stable, wherein a sensor is provided at the outlet of the air conditioner to monitor the exhaust air temperature and a controller to receive signals from the sensor is provided to control the activation of the three-way electric valve.
