Abstract [en]

Sweden has an ambitious plan to fully decarbonise district heating by 2030 and to contribute with negative emissions of greenhouse gases in 2050. The vagaries of the energy market associated with climate, political, and social changes entail cross-sectoral integration that can fulfill these national targets. Fifth-generation district heating and cooling (5GDHC) is a relatively new concept of district energy systems that features a simultaneous supply of heating and cooling using power-to-heat technologies. This paper presents best practices for developing 5GDHC systems in Sweden to reach a consensus view on these systems among all stakeholders. A mixed-method combining best practice and roadmapping workshops has been used to disseminate mixed knowledge and experience from middle agents representing industry professionals and practitioners. Four successful implementations of 5GDHC systems are demonstrated and the important learned lessons are shared. The best practices are outlined for system planning, system modeling and simulation, prevailing business models for energy communities, and system monitoring. A roadmap from the middle agents’ point of view is composed and can be utilised to establish industry standards and common regulatory frameworks. © 2023 The Author(s)

Abstract [en]

In this study, a completely new type of air-to-liquid heat exchanger, adapted for obtaining good heat transfer performance even at a laminar flow regime on the liquid side has been evaluated in a display cabinet application. The heat exchanger consists of parallel plates, with liquid in every second passage and air in the other passages. Tests were performed with a traditional open vertical display cabinet, first with a traditional finned-tube coil and thereafter with the new type of heat exchanger, both in a climate chamber and thereafter in the field. The results from both tests showed that the liquid inlet temperature could be increased by around 6°C, from the range -8°C - -7°C with the traditional coil to the range -2°C -1°C with the new type of heat exchanger, which can lead to considerable energy savings and operation without the need for defrosting of the heat exchanger.

Abstract [en]

In the supermarket environment three factors must be considered: food (food quality), personnel (working conditions), and customers.The customers do not remain in this environment very long but are of particular interest since they constitute the supermarket’s commercial basis. However, there are no recommendations on the indoor environment based on this category. This study compares the perceived indoor thermal environment with simultaneous objective measurements of the thermal environment and includes multiple enquiry methods. These methods have been used for this specific environment in order to understand how customers perceive, evaluate, and prefer variations in the thermal environment.

Measurements were performed in summer and winter in front of twelve display cabinets, over 1100 questionnaires have been received.To provide recommendations, this study presents measured and perceived comfort in supermarkets, information which can be used for prescribing suitable thermal environments for customers.

Abstract [en]

With the increasing use of air source heat pumps, noise disturbance can be a barrier for further market growth and acceptance. Both steady state noise level and noise events influence reported noise disturbance. In this study one of the transient noise events was investigated: the noise initiated when the heat pump shifts to defrost mode. The results show that noise from a heat pump at defrost initiation was strongly dependent on the pressure differences in the system at the time of the shift. A reduced pressure difference resulted in a lower noise level. A control strategy that adds an idling time for the heat pump just before the shift of the 4-way valve is therefore suggested. This will have a small negative effect (<3%) on the heat capacity of the heat pump but the effect upon the COP will be negligible.

Abstract [en]

In a supermarket setting, customers likely feel the chilled air from refrigerated units displaying their contents to passing customers. Supermarkets, by their nature, contain a diverse range of perishable goods stored in different designed units within one large building, whose distinct storage temperatures result in the unusual thermal environment that customers encounter when shopping. Unfortunately, this open environment results in huge amounts of wasted cold air from display units, the reduction of thermal comfort for customers, and a reduction in the quality of the food. A possible solution to improve comfort for customers, reduce cold air waste, help preserve foods, and save money for retailers includes innovative doors for open display cabinets. Such doors will save money for the retailer by lowering the costs for energy in supermarkets. Doors should, therefore, be viewed as an option and solution for not only the merchandiser, but also for the customer.

Abstract [en]

In the outdoor unit of an air-source heat pump the fan is a major noise source. The noise level from the fan is dependent on its state of operation: high air-flow and high pressure drop often result in higher noise levels. In addition, an evaporator that obstructs an air flow is a noise source in itself, something that may contribute to the total noise level. To be able to reduce the noise level, heat exchanger designs other than the common finned round tubes were investigated in this study. Three types of heat exchanger were evaluated to detect differences in noiselevel and air-side heat transfer performance at varying air flow. The measured sound power level from all the heat exchangers was low in comparison to the fan sound power level (directeffect). However, the heat exchanger design was shown to have an important influence on the sound power level from the fan (indirect effect). One of the heat exchangers with flat tubes was found to have the lowest sound power level, both direct and indirect, and also the highest heat transfer rate. This type of flat tube heat exchanger has the potential to reduce the overall noise level of a heat pump while maintaining heat transfer efficiency.

Abstract [sv]

On behalf of the Swedish Energy Agency, SP has investigated and recommended how one could form a platform for demonstration of single family houses as nearly zero energy houses. SP suggests that TMF, the national trade and employers’ association of the wood processing and furniture industry in Sweden, should administrate this platform. The reason being that members of TMF produce almost 80% of all single family houses in Sweden. TMF also has the capacity to launch a demonstration platform in a reasonable short time. SP has also compiled a set on technical criteria regarding properties related to energy use that should be met by demonstration projects within the platform. One presumption has been that a house that meets the criteria in the south of Sweden also should meet the criteria in the north of Sweden. The reason being to promote an industrialized and cost effective building process. Another ambition has been not to disfavor smaller single family houses. The main criteria are on very energy efficient building envelopes and very efficient building services systems. The criteria are therefore more detailed than the current Swedish building regulations.
