  • Hvac System Covid Procedures
    HVAC SYSTEM COVID PROCEDURES August 17, 2020 Prepared by: Johnson Roberts Associates 15 Properzi Way Somerville, MA 02143 Prepared for: City of Cambridge Executive Summary The HVAC COVID procedures are a compilation of Industry Standards and CDC recommendations. However, it should be noted that good PPE (personal protective equipment), social distancing, hand washing/hygiene, and surface cleaning and disinfection strategies should be performed with HVAC system measures, as studies have shown that diseases are easily transmitted via direct person to person contact, contact from inanimate objects (e.g. room furniture, door and door knob surfaces) and through hand to mucous membrane (e.g. those in nose, mouth and eyes) contact than through aerosol transmission via a building’s HVAC system. Prior to re-occupying buildings, it is recommended that existing building HVAC systems are evaluated to ensure the HVAC system is in proper working order and to determine if the existing system or its associated control operation can be modified as part of a HVAC system mitigation strategy. Any identified deficiencies should be repaired and corrected, and if the building HVAC system is a good candidate for modifications those measures should be implemented. In general HVAC system mitigation strategies should include the following recommendations: 1. Increase Outdoor Air. The OA increase must be within Unit's capacity in order to provide adequate heating or cooling so Thermal Comfort is not negatively impacted. Also use caution when increasing OA in polluted areas (e.g. High Traffic/City areas) and during times of high pollen counts. 2. Disable Demand Control Ventilation where present.

Received: 21 January 2020; Accepted: 24 February 2020; Published: 27 February 2020 Abstract: Looking at the waste heat potential made available by industry, it can be noted that there are many sectors where small scale (< 100 kWe) organic Rankine cycle (ORC) plants could be applied to improve the energy efficiency. Such plants are quite challenging from the techno-economic point of view: the temperature of the primary heat source poses a low cutoff to the system thermodynamic efficiency. Therefore, high-performance components are needed, but, at the same time, they have to be at low cost as possible to assure a reasonable payback time. In this paper, the design of a two-stage radial in-flow turbine for small ORC industrial plants is presented. Compared to commonly applied mono-stage expanders (both volumetric and dynamic), this novel turbine enables plants to exploit higher pressure ratios than conventional plants. Thus, the theoretical limit to the cycle efficiency is enhanced with undoubted benefits on the overall ORC plant performance.

  • Microgeneration Strategy: Progress Report
    MICROGENERATION STRATEGY Progress Report JUNE 2008 Foreword by Malcolm Wicks It is just over two years since The Microgeneration Strategy was launched. Since then climate change and renewables have jumped to the top of the global and political agendas. Consequently, it is more important than ever that reliable microgeneration offers individual householders the chance to play their part in tackling climate change. In March 2006, there was limited knowledge in the UK about the everyday use of microgeneration technologies, such as solar thermal heating, ground source heat pumps, micro wind or solar photovolatics. Much has changed since then. Thousands of people have considered installing these technologies or have examined grants under the Low Carbon Buildings Programme. Many have installed microgeneration and, in doing so, will have helped to reduce their demand for energy, thereby cutting both their CO2 emissions and their utility bills. The Government’s aim in the Strategy was to identify obstacles to creating a sustainable microgeneration market. I am pleased that the majority of the actions have been completed and this report sets out the excellent progress we have made. As a consequence of our work over the last two years, we have benefited from a deeper understanding of how the microgeneration market works and how it can make an important contribution to a 60% reduction in CO2 emissions by 2050. Building an evidence base, for example, from research into consumer behaviour, from tackling planning restrictions and from tracking capital costs, means that we are now in a better position to take forward work on building a sustainable market for microgeneration in the UK.

  • The Potential and Challenges of Solar Boosted Heat Pumps for Domestic Hot Water Heating
    Solar Calorimetry Laboratory The Potential and Challenges of Solar Boosted Heat Pumps for Domestic Hot Water Heating Stephen Harrison Ph.D., P. Eng., Solar Calorimetry Laboratory, Dept. of Mechanical and Materials Engineering, Queen’s University, Kingston, ON, Canada Solar Calorimetry Laboratory Background • As many groups try to improve energy efficiency in residences, hot water heating loads remain a significant energy demand. • Even in heating-dominated climates, energy use for hot water production represents ~ 20% of a building’s annual energy consumption. • Many jurisdictions are imposing, or considering regulations, specifying higher hot water heating efficiencies. – New EU requirements will effectively require the use of either heat pumps or solar heating systems for domestic hot water production – In the USA, for storage systems above (i.e., 208 L) capacity, similar regulations currently apply Canadian residential sector energy consumption (Source: CBEEDAC) Solar Calorimetry Laboratory Solar and HP water heaters • Both solar-thermal and air-source heat pumps can achieve efficiencies above 100% based on their primary energy consumption. • Both technologies are well developed, but have limitations in many climatic regions. • In particular, colder ambient temperatures lower the performance of these units making them less attractive than alternative, more conventional, water heating approaches. Solar Collector • Another drawback relates to the requirement to have an auxiliary heat source to supplement the solar or heat pump unit,

  • Refrigerant Selection and Cycle Development for a High Temperature Vapor Compression Heat Pump
    Refrigerant Selection and Cycle Development for a High Temperature Vapor Compression Heat Pump Heinz Moisia*, Renè Riebererb aResearch Assistant, Institute of Thermal Engineering, Graz University of Technology, Inffeldgasse 25/B, 8010 Graz, Austria bAssociate Professor, Institute of Thermal Engineering, Graz University of Technology, Inffeldgasse 25/B, 8010 Graz, Austria Abstract Different technological challenges have to be met in the course of the development of a high temperature vapor compression heat pump. In certain points of operation, high temperature refrigerants can show condensation during the compression which may lead to compressor damage. As a consequence, high suction gas superheat up to 20 K can be necessary. Furthermore high compressor outlet temperatures caused by high heat sink outlet temperatures (approx. 110 °C) and high pressure ratios can lead to problems with the compressor lubricant. In order to meet these challenges different refrigerant and cycle configurations have been investigated by means of simulation. Thermodynamic properties as well as legal and availability aspects have been considered for the refrigerant selection. The focus of the cycle configurations has been set on the realization of the required suction gas superheat. Therefore the possibility of an internal heat exchanger and a suction gas cooled compressor has been investigated. The simulation results showed a COP increase of up to +11 % due to the fact that the main part of the suction gas superheat has not been provided in the evaporator. Furthermore, the effect of increased subcooling has been investigated for a single stage cycle with internal heat exchanger. The results showed a COP of 3.4 with a subcooling of 25 K at a temperature lift of approximately 60 K for the refrigerant R600 (n-butane).
