Climate control

The main advantage of wholesale climate control Hes in easy access to the objects, and the absence of differences in conditions between various spaces within the institution, eg, storage areas, conservation laboratories, and exhibition galleries. The actual values set for the rh are a matter of compromise metals, stone, and ceramics are best served by humidities as low as possible, but organic materials generally require higher values. An accepted... 

Pollutants. The problems posed by ak pollutants are very serious. Within a museum, measures can be taken to remove harmful substances as efficiently as possible by means of the installation of appropriate filter systems in the ventilation equipment. Proposed specification values for museum climate-control systems requke filtering systems having an efficiency for particulate removal in the dioctyl phthalate test of 60—80%. Systems must be able to limit both sulfur dioxide and nitrogen dioxide concentrations <10 /ig/m, and ozone to <2 /ig/m. ... 

Hydrogen sulfide has traditionally been a problem in the tarnishing of silver and the discoloration of bronze patinas. This gas can be dealt with in the filters of the climate-control system as well as through the use of proper absorbing agents. For example, a paper treated with activated charcoal is fabricated especially for absorbing H2S within a microclimate. 

Certain state highway authorities are studyiag the use of ftber-reiaforced polymers, typically thermosets such as epoxy or unsaturated polyester, for bridge constmction. On an even more futuristic scale, fiber optics that employ polymeric jacketing and, ia some cases, optically active polymeric cores, may someday be employed ia place of wines for home security systems, climate control, etc (10,91). 

As the world s population increases, economic affluence is also increasing in many regions. Affluence usually means more business providing more goods and seiwices more homes and business with more climate control more use of appliances and electronic technology in homes and businesses and more miles logged by more automobiles, trucks, trains, and air-... 

Four-pipe system This layout uses HW supply and return pipes for space heating (pipes 1 and 2) and chilled-water pipes for space cooling (pipes 3 and 4). Effective building climate control by conventional means is easier with a four-pipe system, but the piping costs obviously are much higher. 

In evaluating the influence of individual climate controls, we have three major concerns the time frame over which the control operates, the potential magnitude of the control s influence on climate, and whether a strong correlation between some forcing phenomenon and climatic response actually indicates a cause-effect relationship. 

Individual climate controls do not function in isolation from one another rather, many factors link together in complex cause-effect chains (Figure 2). Factor interactions may involve feedback loops that at one extreme amplify... 

Unpigmented paint samples were brushed onto a potassium bromide crystal or polyethylene sheet (paint film thickness about 5 microns) and stored at controlled relative humidity using saturated salt solutions in closed vessels or a climate controlled room.

The materials for uniforms and equipment will need to provide protection from chemical and biological agents (and perhaps detect them as well), be lightweight, and provide climate control to maintain performance in extreme environments. New medicines—antivirals, antibiotics, and antifungals—will be needed to maintain the health of troops deployed in such locations. In urban areas, advanced materials are needed for robots that can enter buildings before soldiers.

More and more sensors and microsystem devices are being used in a wide range of household appliances, and the number is set to increase in the near future. Several technologies are used for such sensors, as described in the subchapters of Chapter 5. An evaluating synopsis of these sensors is given in Tab. 1.2 for large household appliances, for small household appliances in Tab. 1.3 and for heating and climate control in Tab. 1.4. 

Several sensors are in use in the heating and climate control sector, such as... 

Tab. 1.4 Development status of devices for heating and climate control.

The household appliance field comprises several families of large household appliances, small appliances, heating and climate control devices and security instrumentation, as described in Chapter 1. The total turnover of all these appliances is estimated at over 90 billion worldwide. The worldwide production of larger appliances could be about 150 million units [1],... 

Heating and climate control are essential for comfort, and people have always been looking for improvement in this field. In large rooms, such as offices or public buildings (e.g. concert halls), automatic temperature control has become increasingly important. The creation of a comfortable climate is far more complex...

The Quaranta is a concept hybrid gas/electric vehicle with solar assist. The electric portion is made by Italdesign Giugiaro. The roof is a solar panel that charges the batteries and provides energy for the climate control system. The all wheel drive, mid-engined car accelerates from zero to 62 mph (100 kph) in 4.05 seconds and tops out at 155 mph. This is a three-seat high performance sports car.
