6.- Some characteristics of the housing.
Characteristics of solar domestic hot water. The necessary facilities are available so that
most of the hot water comes from solar energy. Solar vacuum tubes suitable for
installation in vertical with good performance in winter, to become more perpendicular
radiation will be installed for the homes of the south facade. For North-oriented housing
will be mounted on the cover a centralized installation of solar flat plate at an angle of
53° Southeast, from which hot water is distributed to homes in which individual counters
will be installed to be able to control the consumption of each separately (Fig 10).
Trombe wall with convective loop. A canvassing with convective loop system, is
projected to achieve a better distribution of the
captured heat as well. It is necessary an
intermediate space in which occurs the uptake of
radiation and a separator element of the room
capable of storing heat; within the wall hot air rises
and goes into the room while the same cold air
moves to the intermediate Chamber. This air heats
up, will rise and the process will be repeated
cyclically. The intermediate layer (accumulator
element) consists of a panel type formacore (a set of
copper plates in diaper, to lighten the weight without
giving up the heat capacity of the metal), heavily
insulated so that eliminates the thermal conduction
and, therefore, all the heat accumulated by this layer
during the insolation, will follow by heating the air
when direct sunlight disappears, i.e. at night. At this
time of the day are expected to cover the exterior glass with a shutter textile isolate that
reduce the loss of heat to the outside.
Wall heat recoil buffer. This system aims to create a convective loop so that in an
intermediate Chamber, heavily insulated exterior recovers part of the heat brought to the
room. The situation of the wardrobes in the façade will provide true isolation. The flow
that goes through this "insulating layer" will be used to heat the air contained in the
