Heating and Cooling System

Several attempts have been made to model the flow through porous media and to predict the pressure drop as a function of flow rate and polymer flow properties. A number of interesting articles [13-26] are listed in the references.

Wastage is pronounced in equipment contacting high-pH fluids. Chemical process equipment, heat exchangers, water-cooled process reactors, valving, transfer pipes, and heating and cooling systems are often affected. 

An active solar heating and cooling system consists of a solar energy collector (flat plate or concentrating), a storage component to supply heat when the... 

In Table 9 the recent statistics of ATES utilisations in Sweden are presented. As can be seen the technology is so far preferably used for commercial and institutional buildings with small or medium sized applications. Large-scale plants are applied for some district heating and cooling systems while the industry sector only has a couple of systems applied for manufacturing industries. The rest represents cooling in the telecom sector. 

Abstract. Newly established residential area in Vastra Hamnen (West Harbour) in the city of Malmo uses Aquifer Thermal Energy Storage (ATES) as part of the district heating and cooling system. ATES system has 5 warm and 5 cold wells that are 70-80 m deep. Cold from the nearby sea (Oresund) and water cold from heat pump is stored from winter to summer. The purpose of the system is to deliver free cooling to district cooling system at a temperature level below +6-8 °C. Operational experiences and economic aspects are discussed. 

The initial cost of an ACES is much higher than that for conventional home heating and cooling systems, mainly because of the cost of the storage tank. Energy savings in a house with electric resistance backup can be over 1,000 per year, which gives about a 10- to 15-year payback. 

The heating and cooling system ensures rapid heating and cooling of the heat-transfer medium. The installation of additional intermediate silos for cooling the final polymer shortens the residence time of the polymer in the reactor and helps to increase its capacity.

In order to control the reaction course and so avoid a runaway incident, it is essential to understand how heating-cooling systems of reactors work and what their performance is. These topics are reviewed in this chapter, where different heating and cooling systems are reviewed from the particular implications on process safety. In the first section, the different heating and cooling techniques...
