Abstract
A cooling system can include a primary cooling loop having a primary cooling fluid, a secondary cooling loop having a secondary cooling fluid, a heat exchanger for transferring heat to the primary cooling fluid from the secondary cooling fluid, and a controller. The heat exchanger can be a brazed plate heat exchanger arranged for providing a low supply temperature of the secondary cooling fluid supplied to a load. The system can increase the supply temperature by injecting hot secondary cooling fluid upstream of the load, such as by using a bypass valve in the secondary cooling loop.
Claims20
A cooling system comprising:
- a primary cooling loop having a compressor configured to compress a primary cooling fluid;
- a heat exchanger configured to transfer heat to the primary cooling fluid from a secondary cooling fluid;
- and
- a secondary cooling loop having:
- a prime mover configured to circulate the secondary cooling fluid through a load;
- and
- a bypass valve plumbed in parallel with the heat exchanger and configured to selectively permit a bypass portion of the secondary cooling fluid to bypass the heat exchanger.
