Benefits of technology

The invention provides a method of heat exchange that overcomes or mitigates the disadvantages or defects of prior art. It involves a heat pump assembly for controlling an indoor fluid's temperature with a heat exchange fluid circulatable in a heat exchanger. Ground loop circuits are provided, with end portions positioned proximal to the heat exchanger and one or more pipe portions having embedded parts positioned in the pipe body. Connecting portions are provided to allow the heat transfer medium to circulate between the end portion(s) and the pipe body. Heat transfer is permitted between the heat transfer medium and the fluid in the conduit, as well as between the heat transfer medium and the pipe material and ground material surrounding the pipe body. The heat transfer medium is moved through the pipe portions and the end portion of the ground loop circuit, and heat exchange is also simultaneously allowed with the heat exchange fluid and the pipe portions. The invention is suitable for heat exchange in various settings and can provide efficient and effective cooling or heating for buildings and other structures.

Problems solved by technology

However, the known heat pump systems have a number of disadvantages.

Embodiment Construction

[0023]In the attached drawings, like reference numerals designate corresponding elements throughout. Reference is first made to FIGS. 1-5A to describe an embodiment of a heat exchange system 20 of the invention. In one embodiment, the heat exchange system 20 includes a heat pump assembly 22 for controlling an indoor fluid's temperature having a heat exchanger 24 with a heat exchange fluid 26 circulatable therein (FIG. 4). Preferably, the heat exchange system 20 includes one or more elongate pipe bodies 28, each pipe body 28 defining one or more conduits 30 therein in which one or more fluids 32 are receivable (FIGS. 2, 3B, 5A). Each pipe body 28 also includes an exterior surface 34 which is adapted for engagement with ground material 36. In one embodiment, the heat exchange system 20 preferably also includes one or more ground loop circuits 38 in fluid communication with one or more pumps 40 (FIG. 4), for circulating a heat transfer medium 42 through each ground loop circuit 38. As ...

Abstract

A method for heat exchange with a heat transfer medium including providing a ground loop circuit through which the heat transfer medium is circulatable. The circuit includes an end portion, positioned proximal to a heat exchanger, one or more pipe portions having embedded parts thereof positioned in pipe bodies. Each pipe body defines a conduit therein through which a fluid is flowable, and has an exterior surface engaged with ground material. The method also includes circulating the heat transfer medium through the ground loop circuit, to permit heat transfer between the heat transfer medium moving through the embedded part and the fluid in the conduit, and heat transfer between the heat transfer medium moving through the embedded part and the ground material engaged with the pipe body.

Description

[0001]This is a divisional of co-pending application Ser. No. 12 / 728,366, filed on Mar. 22, 2010, which claims the benefit of U.S. Provisional Patent Application No. 61 / 161,948, filed Mar. 20, 2009, each of which prior application is incorporated herein in its entirety by reference.FIELD OF THE INVENTION[0002]The present invention is a method of heat exchange in which a heat transfer medium is circulated through a circuit for heat exchange with fluid flowing through a pipe buried in ground material, and for heat exchange with the ground material.BACKGROUND OF THE INVENTION[0003]Heat pumps, and in particular geothermal heat pumps, are well known in the art. In general, geothermal heat pumps are adapted to draw energy from shallow ground, i.e., energy from the sun which is stored in the ground. The shallow ground is used as a heat source (i.e., when the heat pump is used to provide heat to an indoor space in a building), or a heat sink (i.e., when the heat pump is operating to cool th...
