Frisse lucht zorgt voor een goede en diepere slaap. Dus bieden veel kinderdagverblijven de mogelijkheid om kleintjes buiten te laten slapen. Kan dat onder alle weersomstandigheden? En waar let je op als het bijvoorbeeld pijpenstelen regent of vriest dat het kraakt?

Pressure pulsations are an intrinsic feature of reciprocating compressor systems, that may lead to various issues. The API 618 standard is the most relevant guideline for pulsation and vibration control during the design stage. However, the main focus of API 618 is on pulsation effects in the field piping, and less on the pulsations close to the...

Onze buitenlucht is schoner dan de lucht in woningen. Deze treurige constatering werd onlangs gedaan tijdens de 'Dag van de Binnenlucht', die werd georganiseerd door onder andere de VLA en Isso. Klopt het wel? We belden TNO-onderzoeker Piet Jacobs op om hem hierover aan de tand te voelen.

For a large new refinery project in the Middle East, the design and construction of a very large hydrogen compression unit was required. The compression unit design resulted in the requirement for six large reciprocating compressors operating in parallel, with a total installed electrical power close to 100 MW. The compressors have common...

Recirculation hoods equipped with carbon and plasma filters are becoming more and more popular. The aim of this study is to determine the effectiveness of recirculation hoods with regard to PM2 5 and NOx removal in a 26 m3 lab kitchen with a gas furnace. With the carbon filter PM2 5 is reduced for about 30%. A fresh carbon filter removed about...

Het innovatieprogramma Energiesprong is eind 2016 beëindigd en opgevolgd door de Stroomversnelling, een initiatief van bouwers en woningcorporaties om Nom-renovaties op gang te brengen. Met het afronden van de Energiesprong is de tijd gekomen om in de volle breedte de stand op te maken van wat we vanuit de woningmonitoring hebben geleerd van de...

The AIVC Technical note 68 "Residential Ventilation and Health" summarises studies that prioritise pollutants in the indoor environment and presents a summary of pollutants driving the indoor health risks and their sources. It also describes methods to reduce exposures of contaminants using different control strategies with a special emphasis on...

Fijnstof met een deeltjesgrootte tot en met 2,5 µm (PM2,5) veroorzaakt met afstand de grootste gezondheidslast in vergelijking met andere binnenmilieufactoren. TNO toont aan dat pieken aan fijnstofconcentratie rond het koken in huis verantwoordelijk zijn voor circa 30% van de totale blootstelling aan fijnstof, inclusief de blootstelling die in...

The spatial distribution of Particulate Matter has been studied during class time in a naturally ventilated classroom. Measurements were taken between the pupils at breathing height, and at the side and front between 0,15 and 4 m height. With regard to PM1, PM2,5 and PM10, hardly any differences were observed in concentration, between the...

In the frame of the OFFICAIR project, office buildings were investigated across Europe to assess how the office workers are exposed to different particulate matter (PM) characteristics (i.e. PM2.5 mass concentration, particulate oxidative potential (OP) based on ascorbate and reduced glutathione depletion, trace element concentration and total...

In dit artikel wordt specifiek ingegaan op de Nederlandse regelgeving voor kachels en open haarden en tevens een vergelijking gemaakt met de buitenlandse regelgeving. Nederland blijkt in Europa nogal achter te lopen wat betreft regelgeving voor fijnstofemissie vanuit houtstook. In 2022 wordt Europese regelgeving van kracht, die helaas niet gaat...

Especially in airtight low energy dwellings exhaust systems are of utmost importance as cooking can be a major source of PM2.5 exposure. Dwellings should be designed including facilities enabling extraction of at least 83 dm3/s (300 m3/h) directly to outside. Residents should be able to select an effective hood

Mensen zijn meer dan 90% van de tijd binnen, waarvan een groot deel in hun eigen woning. Dit artikel beschrijft de resultaten van onderzoek naar de concentratie van PM2.5 fijnstof in 9 woningen. In 2016 heeft TNO onderzoek gedaan naar fijnstof in woningen in het kader van het Technologiecluster Effectieve en energiezuinige Afzuigkappen. Dit...

There is established evidence linking exposure to fine particulate matter (PM2 5) to adverse health effects. As people spend the majority of their time indoors, and with the trend towards increasing building air tightness, exposure to PM2 5 indoors is expected to increase, without additionalpurpose provided ventilation. Cooking has been...

This paper presents the results of a study into the functional requirements and optimisation of the CO2 shipping chain, with a focus on the offshore offloading system. The goal was to evaluate the feasibility of a generic approach to the development of ship-based CO2 transport and storage systems in the North Sea, using a range of typical North...

Liquid loading is the mechanism that is associated with increased liquid hold-up and liquid back flow at lower gas flow rates in gas production wells. In laboratory, most liquid loading experiments are performed at fixed gas and liquid rates (mass flow controlled). In the field, the well behavior is a coupled well-reservoir system in which the...

Damping in pipes quantifies the attenuation of the pressure amplitude due to losses. Applications with mixtures of two immiscible phases are common but limited studies on damping with multiphase flows in pipes are available. The purpose of this work is to describe the setup as well as the post-processing used to quantify the acoustical damping...

Foam assisted lift is a deliquification method in the oil and gas industry, which aims to prevent or postpone countercurrent gas-liquid flow in maturing gas wells or to assist in removing downhole accumulated liquids. According to Nimwegen, who performed experiments with foam flows, foam accomplishes this, since the creation of foam postpones...
