Abstract
This paper introduces a ventilation system
that combines buried-pipes with multi-purpose windows
with the aim of finding an energy efficient, environment-protecting
and low-cost way to improve
the indoor environment. In this system, buried pipes serve as air-conditioners and multi-purpose windows serve
as draught, sound and heat protective devices, in addition to acting as
ordinary windows. Further benefits include protection from noise, dust, and
insects as well as protection against intruders, thus providing a safe, healthy
and comfortable indoor environment. This paper presents an
engineering application of this system, and first elaborates the design and construction, then reports
the field tests of the system performance for a typical winter day and a typical
summer day. The results of the field tests show that the indoor acoustic
environment and index of air changes satisfy the requirements of Chinese
residential building codes, and that the indoor thermal environment is
comfortable in summer, and acceptable in winter.
Key words: buried-pipes
technique, multi-purpose window, indoor environment, thermal comfort,
ventilation.
