Solar Space Heating and Cooling Systems

2012
This chapter examines solar space heating and cooling systems. Initially, the basic system configurations are presented which include active solar systems in which direct circulation systems, indirect water-heating systems, and air water-heating systems are presented, space heating and service hot water systems which include air and water systems ...

Space Cooling of nZEB

2019
The International Energy Agency (IEA) predicts that the final energy demand for cooling worldwide will increase from current 4 to 9 EJ per year by the year 2050. There are several reasons for increased energy demand. The contemporary architecture trend of “all-glass” architecture is a significant reason for the increased energy need for cooling of the ...

On-chip cooling for detectors in space applications

2008 IEEE Sensors, 2008
Miniature Joule-Thomson (JT) coolers can be used for cooling small optical detectors. Both, cooler and detector can be integrated on a single chip by means of micro-electromechanical systems technology. For future space missions, the European Space Agency is interested in on-chip detector cooling for the temperature range 70 K - 250 K.

Solar facade for space cooling

Energy and Buildings, 2012
Abstract A building integrated cooling facade is proposed in this paper. It is a fan-assisted system that consists of two vertical plenums. The first plenum was made of black aluminium transpired plate and a sandtile wall, while the second plenum is formed by the sandtile wall and the building wall. The aluminium plate served as a solar collector and

Orbits for radiatively cooled space telescopes

Space Science Reviews, 1992
This paper first outlines the assumed mission requirements for a radiatively cooled space telescope such as EDISON. A summary of relevant characteristics (payload, operating orbit, launcher, lifetime, etc.) for current and proposed cooled telescope missions is then given.

Transient Cooling of a Sphere in Space

Journal of Heat Transfer, 1970
A method is presented for determining the transient temperature distribution of a solid sphere cooling in space. The sphere is assumed initially to be at a uniform temperature and then instantaneously subjected to the radiation sink of space at time zero. This nonlinear problem was solved by using finite-difference computing techniques.

Cooling System for Space Application

2002
In this paper a miniature single-stage Stirling cryocooler for cooling a MCT infrared detector is introduced. The concept of the cryocooler is based on the Oxford-type Stirling refrigerator featuring special flexure suspension springs, linear drive motors, and clearance seals without wear for long-term operation.

Mechanical Cooling Systems for use in Space

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 1993
This paper describes the development of long-life cooling systems for use in spacecraft. The original single-stage coolers were developed by the Rutherford Appleton Laboratory (RAL) and Oxford University for the Improved Stratospheric and Mesospheric Sounder (ISAMS), an Oxford University instrument that will be part of the National Aeronautics and ...

AKARI: space infrared cooled telescope

Experimental Astronomy, 2009
AKARI, formerly known as ASTRO-F, is the second Japanese space mission to perform infrared astronomical observations. AKARI was launched on 21 February 2006 (UT) and brought into a sun-synchronous polar orbit at an altitude of 700 km by a JAXA M-V rocket.
