    Page 1 OPTIMAL ENERGY MANAGEMENT OF HVAC SYSTEMS BY USING EVOLUTIONARY ALGORITHM Session Number: CIB T2S5 Authors Fong K F, BEng, MSc, CEng, MCIBSE, MHKIE, MASHRAE Hanby V I, BSc, PhD, CEng, MInstE, MCIBSE Chow T T, PhD, CEng, MIMechE, MCIBSE, FHKIE, MASHRAE Abstract The available plant and energy simulation packages become robust and user-friendly, and this is the major reason that they are so popular even in the consultancy fields in these few years. In fact, these plant and energy simulation packages can be widely adopted in studying different alternatives of the operation of HVAC and building services systems. Since there are many parameters involved in different equipment and systems, one of the useful areas of studies is to optimize the essential parameters in order to provide a satisfactory solution for design or operation in terms of efficient and effective facilities management. Therefore in this paper, the simulation-optimization approach is proposed for effective energy management of HVAC systems. Due to the complexity of the HVAC systems, which commonly include the refrigeration, water and air side systems, it is necessary to suggest optimal conditions for different operation according to the dynamic cooling load requirements throughout a year. A simulation-EA coupling suite has been developed by using the metaheuristic skill, and the evolutionary algorithm can be effectively used to handle the discrete, non-linear and highly constrained characteristics of the typical HVAC and building services optimization problems. The effectiveness of this simulation-EA coupling suite has been demonstrated through the establishment of the monthly optimal reset scheme of the chilled water supply temperature of a local central chiller plant.

  • Ene04 Low Carbon Design Low and Zero Carbon Technologies
    Ene04 Low carbon design Low and zero carbon technologies Actions: i. Implement LZC (low and zero carbon) technologies in-line with the LZC feasibility study ii. Implement passive design measures and free cooling technologies in line with the previous analysis undertaken Recognised local LZC technologies Technologies eligible to contribute to achieving the criteria must produce energy from renewable sources and meet all other ancillary requirements as defined by Directive 2009/28/EC. Local does not have to mean on site – community schemes near to the site can be used as a way of demonstrating compliance. The following requirements must also be met: 1. There must be a direct supply of energy produced to the building under assessment. 2. Technologies under 50 kWe or 45 kWth must be certified by a Microgeneration Certification Scheme (MCS), or equivalent, and installed by MCS (or equivalent) certified installers. 3. Combined heat and power (CHP) schemes above 50 kWe must be certified under the CHPQA standard. CHP schemes fuelled by mains gas are eligible to contribute to performance against this issue. 4. Heat pumps can only be considered as a renewable technology when used in heating mode. Refer to Annex VI of Directive 2009/28/EC for more detail on accounting for energy from heat pumps. 5. Where MCS or CHPQA certification is not available, the design team must investigate the availability of alternative accreditation schemes in line with the Directives listed above, or an equivalent country or regional directive or standard. Where an accreditation scheme exists, it should be used for the purpose of verifying compliance of the specified LZC technology.

SEGU MADAR MOHAMED RIFAI Student Number: 731222 A-315 Approved Examiner Supervisor at KTH Date: 05/06/2012 Prof. Björn Palm Dr. Samer Sawalha Local Supervisor Dr. Hari Gunasingam Commissioner Contact person i | P a g e Abstract Demand for cooling has been increasing around the world for the last couple of decades due to various reasons, and it will continue to increase in the future particularly in developing countries. Traditionally, cooling demand is met by decentralised electrically driven appliances which affect energy, economy and environment as well. District Cooling Plant (DCP) is an innovative alternative means of providing comfort cooling. DCP is becoming an essential infrastructure in modern city development owning to many benefits compared to decentralized cooling technology. Demand Response Management (DRM) is largely applied for Demand Side management of electrical grid. Demand of electrical energy is closely connected with the demand of alternative form of energy such as heating, cooling and mechanical energy. Therefore, application of DR concept should be applied beyond the electrical grid; in particular, it could be applied to any interconnected district energy systems. District Cooling Plant is one of a potential candidate and Demand Response management solutions can be applied to DCP for sustainable operation.

  • Free Cooling – Outside Air Economizer White Paper #11
    FREE COOLING – OUTSIDE AIR ECONOMIZER WHITE PAPER #11 It’s like opening a window when it’s hot inside and cool outside. How much does it save? The easy answer is ‘it depends.’ To really find out, read further. You’ll see there are a lot of factors. Like all heat recovery concepts, a pre-requisite for success is to have the free heat (or free cooling) available at the same location and time as there is a need for it. The free heat in Atlanta has no practical use in Alaska because they are too far apart. Likewise, free cooling from outdoors doesn’t provide any value unless it is warm indoors at that time. Balance Temperature Buildings are like boxes. They have thermal losses and gains through the shell (envelope), and they also have appliances and activities inside that generate heat. See Figure 1. There will be a point where the envelope loss just matches the internal heat gains and neither heating nor cooling is required; above this ‘balance temperature’, cooling will be required. Source: Commercial Energy Auditing Reference Handbook, 3e Doty,S., Fairmont Press. Figure 1. Thermal Balance Temperature FREE COOLING – OUTSIDE AIR ECONOMIZER White Paper What is your building’s balance temperature? A building’s thermal balance temperature can be estimated with a method called regression, but there are also clues. See Table 1. If there is a lot of heat-producing equipment inside, the building becomes self- heating and will include hours in cooling mode when it is cold outside. Opportunity! If the heating and cooling load is mostly from envelope (not a lot of equipment), the balance point will be higher which means it probably won’t be hot inside while it is cold outside.

  • A Comprehensive Review of Thermal Energy Storage
    sustainability Review A Comprehensive Review of Thermal Energy Storage Ioan Sarbu * ID and Calin Sebarchievici Department of Building Services Engineering, Polytechnic University of Timisoara, Piata Victoriei, No. 2A, 300006 Timisoara, Romania; [email protected] * Correspondence: [email protected]; Tel.: +40-256-403-991; Fax: +40-256-403-987 Received: 7 December 2017; Accepted: 10 January 2018; Published: 14 January 2018 Abstract: Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes. This paper is focused on TES technologies that provide a way of valorizing solar heat and reducing the energy demand of buildings. The principles of several energy storage methods and calculation of storage capacities are described. Sensible heat storage technologies, including water tank, underground, and packed-bed storage methods, are briefly reviewed. Additionally, latent-heat storage systems associated with phase-change materials for use in solar heating/cooling of buildings, solar water heating, heat-pump systems, and concentrating solar power plants as well as thermo-chemical storage are discussed. Finally, cool thermal energy storage is also briefly reviewed and outstanding information on the performance and costs of TES systems are included. Keywords: storage system; phase-change materials; chemical storage; cold storage; performance 1. Introduction Recent projections predict that the primary energy consumption will rise by 48% in 2040 [1]. On the other hand, the depletion of fossil resources in addition to their negative impact on the environment has accelerated the shift toward sustainable energy sources.

  • Hvacwatersystems Waterside Free Cooling.Pdf
    HVAC Water Systems Waterside Free Cooling Summary Free cooling utilizes the evaporative cooling capacity of a cooling tower to indirectly produce chilled water for use in medium temperature loops, such as process cooling loops and sensible cooling loops. Free cooling is best suited for climates that have wetbulb temperatures lower than 55°F for 3,000 or more hours per year. It is most effectively applied to serve process and/or sensible cooling loops that between 50°F–70°F chilled water. Table 1. Free Cooling Application At least 3000 hours per Applicability year where wet bulb temperature is below: 55°F Process cooling water Process cooling, sensible 45°F cooling 35°F All chilled water use 1. Assumes process cooling water is between 60 to 70°F. 2. Assumes sensible cooling water is between 50 to 55°F. Principles • Chilled water systems use chillers that typically operate at 0.5 to 0.7 kW/ton in a partial load regime while free cooling systems typically operate at 0.05 to 0.15 kW/ton. 1 • A flat plate heat exchanger is used to isolate the chilled water loop from the open tower condenser water. With few exceptions, tower water is not reliably clean enough for use directly in the cooling loop. • The approach temperature on a cooling tower is critical for best results. A low approach temperature on the tower is critical to achieve the highest energy savings. • A traditional chiller is used to provide cooling during hot periods and as an always-available emergency backup. For a portion of the year, free cooling offers a non-compressor based backup to the traditional chiller.

Two data center racks one of them is attached with fin and tube thermosiphon were cooled by CRAC unit (computer room air conditioning unit) individually. Thermosiphon can help to partially eliminate the compressor loading of the CRAC; thus, energy saving potential of thermosiphon loop was investigated. The condenser is a water-cooled design and perfluoroalkoxy pipes were used as adiabatic riser/downcomer for easier installation and mobile capability. Tests were conducted with filling ratio ranging from 0 to 90%. The test results indicate that the energy saving increases with the rise of filling ratio and an optimum energy savings of 38.7% can be achieved at filling ratios of 70%, a further increase of filling ratio leads to a reduction in energy saving. At a low filling ratio like 10%, the evaporator starves for refrigerant and a very uneven air temperature distribution occurring at the exit of data rack.

The building sector accounts for more than 40% of the global energy consumption. This consumption may be lowered by reducing building energy requirements and using renewable energy in building energy supply systems. Therefore, a nearly zero-energy building, incorporating a solar heating and cooling system, was designed and built in Beijing, China. The system included a 35.17 kW cooling (10-RT) absorption chiller, an evacuated tube solar collector with an aperture area of 320.6 m2, two hot-water storage tanks (with capacities of 10 m3 and 30 m3, respectively), two cold-water storage tanks (both with a capacity of 10 m3), and a 281 kW cooling tower.
