Abstract

This distribution box is produced in the form of stack (101) of a plurality of substantially parallel plates (P1, P2, P3, P4), each plate Pi having at least one face Fij for contact with a contiguous plate Pj of the stack, one contact face Fij of one plate Pi bearing, on the one hand, at least one impression Eij forming a half pipe which with a half pipe formed by an impression Eji of a contiguous plate Pj forms a pipe parallel to the plane of the plates, and, on the other hand, at least one drilling Tij which with a drilling Tij of a contiguous plate Pj forms at least one element of a pipe perpendicular to the plane of the plates. Application to heat pump-type heating/airconditioning installations in private homes and small multi-storey buildings.

Abstract

The splitter box (10) is coupled to a heat pump (12) and to various heat collecting (24, 28, 30) and heat delivery (38, 40, 52, 56) circuits that it selectively interconnects according to various predetermined fluid-distribution combinational diagrams by automatic control of an inbuilt network of stop valves (200). These diagrams define modes of operation such as natural cooling or frost protection, hot water production and/or air-conditioning from a single plant, by optimizing the transfers of heat between circuits such that the heat pump always operates in its optimum thermodynamic zone.

Abstract

This accessory is intended for digging radial galleries (46, 48) from the same site (12) situated close to the ground level. It comprises a cylindrical or prismatic casing (20) formed by a plurality of sectorial elements (22) which can be uncoupled along generatrices of the casing, such that the sectorial elements can be brought separately and assembled in situ at the drilling site. Each sectorial element is provided with means (28, 30) for assembly to the sectorial elements which are adjacent to it. In the lower part is provided a support (60) which can be freely arranged along the horizontal and provided with a multi-directional frame (58) adapted to receive a drilling machine (50). This multi-directional frame (58) is adjustable in its inclination with respect to the support (60) so that the drilling machine can be positioned in at least one drilling direction (ﶴ, ﶴ') inclined with respect to the horizontal.
