A base HVAC device block (10) comprising a housing (11); an HVAC functional device (M/S); an extension interface (16A); an external electrical interface (18) for the transmission of electrical power and data signal(s); and an electronic circuit (12) connected with the HVAC functional device (M/S). In a first configuration, the base HVAC device block (10) is configured to connect the external electrical interface (18) with the electronic circuit (12) for transmission of data signal(s) and thereby provide HVAC functionality(s) of a first category. In a second configuration, the base HVAC device block (10) is configured to route the transmission of data signal(s) through an add-on electronic circuit (22) of an add-on HVAC device block (20) attached to the base HVAC device block (10) via an add-on interface (26B) of the add-on HVAC device block (20) to thereby provide HVAC functionality(s) of a second category.

A modular structure for hiding HVAC and other rooftop mechanical equipment is provided. The structure is configured to provide easy access around the HVAC and other rooftop equipment, while reducing the amount of holes modifications to the mechanical equipment. The structure allows for a variety of covering walls to hide the rooftop equipment. The structure includes the ability to connect modular support and frame members in a variety of configurations depending on the size and shape of the equipment that needs to be hidden.

A refrigeration and air conditioning device, which is an outdoor unit of a refrigeration and air conditioning device provided with a heat exchanger within a housing (2) and blowers (3) arranged on the housing, the housing (2) being provided with a side cover covering the sides, a base (9) covering the bottom and a foot portion (10) arranged below the base (9), the foot portion (10) being provided with a raised portion (10b) upwardly bending an end face (10c) of a lower surface of the foot portion. The refrigeration and air conditioning device increases rigidity without increasing costs.
