    Sammanfattning : I detta examensarbete simuleras ett värmehanteringssystem i Matlab Simulink för en elektrisk lastbil, det för att värmehantera fordonets klimat. Där en värmepump används för nedkylning av kupé och batteri samt en PTC (elektrisk värmare) för uppvärmning av detsamma. LÄS MER

  3. 2. From Product to Service – The Customer Value of Servitization - A study examining the potential customer value of servitization of the indoor climate

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Constance Ekström Skeppstedt; Clara-Beatha Björck; [2021-07-07]
    Nyckelord :Servitization; Product-Service Systems; Indoor Air Quality; Indoor Climate; HVAC-R Industry; Customer Value; Property Owners;

    Sammanfattning : In an environment that constantly changes and with increasing competition, firms struggle to stay competitive. To be able to compete, firms have to differentiate. One way to do so is through servitization. By offering customers services instead of products, firms can improve their offering to customers by increased customization. LÄS MER

  4. 3. Data mining techniques for modeling the operating behaviors of smart building control valve systems

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Amirmohammad Eghbalian; [2020]
    Nyckelord :Machine learning; Data mining; Outlier detection; Time-series; HVAC R;

    Sammanfattning : Background. One of the challenges about smart control valves system is processing and analyzing sensors data to extract useful information. These types of information can be used to detect the deviating behaviors which can be an indication of faults and issues in the system. LÄS MER

  5. 4. Performance analysis and validation of high-temperature cooling panels in passive geothermal system

    Master-uppsats, KTH/Hållbara byggnader

    Författare :Carlos JImenez Lopez; [2018]
    Nyckelord :Heat Transfer; High Temperature Cooling; Cooling Radiant Ceiling Panels; Computational Fluid Dynamics; HVAC Systems; Cooling Capacity.;

    Sammanfattning : High Temperature Cooling, HTC, is a thermal conditioning strategy, which aims to reducemixing and transfer heat losses. Cooling capacity strongly depends on heat transfer coefficientsand offers a great response and several advantages in terms of efficiency and sustainability. LÄS MER

  7. 5. Corrosion properties of aluminium alloys and surface treated alloys in tap water

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för materialkemi

    Författare :Sofia Gustafsson; [2011]
    Nyckelord :corrosion; aluminium; aluminum; tap water; water;

    Sammanfattning : The aim of this thesis is to obtain a basic knowledge of the factors that affect corrosion of aluminium in tap water for different kinds of applications like water pipes for tap water, solar systems, HVAC&R-applications (like fan coil units on chillers) and heat sinks for electronic or industrial applications. Open systems are used in some applications and closed systems in others. LÄS MER
