A helical pile including a heat exchanger is described. The pile is formed from a lead section and one or more extension sections. The interior of the lead and extension sections are hollow and form a heat exchanger cavity. At the lower end of the lead section is a helical blade. Rotation of the lead section causes the helical blade to screw into the ground, thus pulling the lead section downward. Extension sections are added to the lead section and the pile is rotated until it is installed to a desired depth. The pile includes an inflow tube extending a predetermined distance into the heat exchanger cavity and an outflow port connected with the heat exchanger cavity. In operation, a heat carrying fluid is pumped into the inflow tube from a heat source or sink, for example, a heat pump for a building heating and cooling system. The fluid exits the tube at a point near the bottom of the heat exchanger cavity. The fluid flows upward through the heat exchange cavity and exchanges heat with the surrounding soil. The fluid flows out through the outflow port and back to the heat source or sink.

A convection/radiation air conditioning terminal and an air conditioning system are provided. The convection/radiation air conditioning terminal includes a heat pipe. One end of the heat pipe is connected to a first heat exchange pipeline, and the other end of the heat pipe is connected to a second heat exchange pipeline. The heat pipe includes multiple first microchannels which are arranged and independent of each other, and multiple second microchannels which are arranged and independent of each other, where the first microchannels and the second microchannels are arranged and independent of each other. The first microchannels are each internally provided with a first heat exchange working medium, and the second microchannels are each internally provided with a second heat exchange working medium.

A pivot window includes a laminated body capable of rotating in a state where a first plate material is directed outdoors and in a state where a second plate material is directed outdoors. The laminated body uses at least one of solar heat, atmospheric heat, and atmospheric humidity, and provides a humidity control effect to the room in both of the state where the first plate material is directed outdoors and the state where the second plate material is directed outdoors. The laminated body is not limited to the one providing the humidity control effect, but may be the one providing a temperature control effect. The laminated body may use the concentration of a specific gas in the atmosphere such as atmospheric oxygen concentration, atmospheric carbon dioxide concentration, and atmospheric volatile organic compound (VOC) concentration, and may provide a component concentration adjusting effect to the room.

The device further includes a plurality of folds such that the device has a three-dimensional surface geometry having a plurality of inclined surfaces.

The present invention discloses a preparation method for a hollow radiator and a hollow radiator. The preparation method comprises the following steps: 1) providing a feed and an insert raw material; 2) molding the insert raw material into an insert; 3) placing the insert in a cavity of a mold, and filling the cavity with the feed by injection molding in such a manner that the insert is surrounded by the feed, thereby obtaining a green body with the insert; 4) performing debinding treatment on the green body with the insert to remove the insert, thereby obtaining the green body of a hollow structure; and 5) sintering the green body to obtain the hollow radiator. By the preparation method for a hollow radiator according to the present invention, a radiator of a complex hollow structure can be fabricated, and the heat dissipation effect of the radiator can be improved. Moreover, the airtightness and leakproofness of the radiator can be guaranteed for a long time.

A waste heat recovery for use with refrigeration means and space heating/water heating to meet various seasonal demands on refrigeration and heating energy is disclosed. The system is intended for use with refrigeration means of the conventional type including a compressor and a condenser through which a compressible refrigerant is circulated. The system integrates a refrigeration system and a heating utilization system through a thermochemical system functioning as a heat transfer system and thermochemical energy storage system. Wherein the heat transfer system is used for absorbing the waste heat normally dissipated in the condenser and for discharging the recovered thermal energy to a heat utilization system for space heating and/or water heating, the thermochemical energy storage system is used for converting the waste heat collected into chemical energy for seasonal storage. The waste heat recovery system is designed with a feature that operations of the refrigeration system and the heat utilization system are de-coupled so that the refrigeration system and the heat utilization system can be operated independently at different times on demand. This feature makes implementation of the waste heat recovery system viable for more residential houses, commercial establishments, and industrial processes applications.
