Nevertheless, a big question when considering whether or not to install heat pumps is: how effective and efficient are they at extracting thermal energy from the air? It’s not a straightforward question to answer. In order to evaluate heat pump capabilities and compare products from different manufacturers, a number of standards have been developed which describe the rigorous requirements for testing these devices, including EN 14511 and EN 16147. In the early days, these tests were performed in rooms equipped with conventional HVAC systems, but these are not generally designed to maintain conditions to the required precision. Sharetree saw an opportunity to improve the testing of heat pumps by developing an innovative walk-in environmental chamber specifically for this purpose, which they hope will increase confidence in the test results and encourage more heat pumps to be installed. This objective posed a considerable engineering challenge. The tests required that the environment inside the chamber simulated the outdoor space in which most heat pumps operate, behaving like an infinite volume of air yet with consistent and controllable thermal and flow properties. These conditions also had to be maintained in spite of the cooling and heating cycles that regularly occur during heat pump operation, which would normally alter the baseline conditions within a confined space. Meeting the flow and humidity requirements When testing a heat pump, it is critical that the... --- - Published: 2025-02-10 - Modified: 2025-07-01 - URL: https://sharetree.co.uk/high-volume-bulk-drying-under-variable-loads/ - Categories: Uncategorised Controlling the moisture content of products can often be critical to ensuring that they meet their specifications. It’s not only the final percentage of water that is of importance; the speed at which the product is conditioned can also be a factor. This is especially relevant in foodstuffs, where texture and other physical characteristics are often affected by the rate of either drying or humidifying. The conditions needed for rapid removal of moisture, such as infrared drying using radiant heaters, can sometimes be too extreme and cause damage to products; slower drying over time periods of around 12 hours is often needed in these cases. This time factor can make the difference between a product passing or failing its quality control tests. However, the time needed to condition products cannot prevent a manufacturing process from being economical. A degree of flexibility is needed to help manage peaks and troughs in demand. So when Sharetree engineers were requested to produce a large chamber which would give repeatable drying performance of a bulk product regardless of the loading in the chamber, it tested their engineering ingenuity and their experience in developing chambers with precise environmental control. Not too cold, not too dry The client’s requirement was to dry ‘Gummy’ products, chewable vitamin supplements which have very tight specifications relating to their moisture content. They are very much a ‘Goldilocks’ product: the conditions need to be just right to ensure they have the texture and elasticity needed. The target of extracting 15 litres... --- - Published: 2025-02-10 - Modified: 2025-07-01 - URL: https://sharetree.co.uk/environmental-chamber-for-use-in-a-fume-cupboard/ - Categories: Uncategorised Fume cupboards (also known as fume hoods) are an essential part of almost any laboratory, as they allow chemical or biological substances to be handled without causing exposure to the operator. They provide an enclosed workspace through which an airflow is drawn continuously from front to back, carrying any fumes or dusts away from the worker and out through a rear duct. Depending on the substances being handled, this air can then be passed through suitable decontamination processes before being vented to the atmosphere. Most environmental test chambers are too large to fit inside standard fume cupboards, meaning that there is a risk of exposure when transferring materials between the fume cupboard and the chamber. Sharetree was requested by a client to develop a chamber specifically for use in a fume cupboard, so that hazardous samples could be tested without compromising the protection of workers. One unanswered question when starting this work was: is it possible for a fume cupboard and an environmental chamber to both work as they should when integrated in this ‘Russian doll’ arrangement? The performance of a fume cupboard is strongly affected by the amount of equipment within it and the proximity of items to the front of the cupboard, where the air is drawn in under a sash window. The critical aspect of this work was that neither component must adversely affect the performance of the other. Keeping the air flowing Fortunately, there was already an excellent starting point available—Sharetree’s Slimline range of chambers, which... --- - Published: 2025-02-10 - Modified: 2025-07-01 - URL: https://sharetree.co.uk/airfreight-cargo-conditioning-unit/ - Categories: Uncategorised Events in recent years have highlighted the important issue of transporting temperature-sensitive items around the world, in particular medicines such as vaccines. As these often have limited lifetimes, air travel is frequently the only practical option, but this raises other issues in that aircraft cannot usually carry the heavy refrigeration systems needed to maintain cold conditions indefinitely. The current solution is to use Thermal Isolation Chambers (TICs) to carry the items. These are insulated containers with no active cooling of their own; instead, they rely on their material properties to maintain cold conditions until the items reach their destination and can be transferred to ground-based cold storage. TICs are typically conditioned by freezing before being filled with the cargo, stacked in a shipping container and finally loaded on board the aircraft. This is a time-consuming and labour-intensive process which reduces the available duration of the flight before the contents begin to warm up. As a consequence, an air freight company approached Sharetree to see if they could help deliver an alternative solution. Bringing the cooling to the cargo The new approach that was trialled was to reverse the usual process: load the TICs into the shipping container, cool the container to the required temperature, and then fill the TICs with their temperature-sensitive cargo immediately before loading onboard the aircraft. To further maximise the duration at which cold conditions would be maintained, the idea was to complete the conditioning of the shipping container at a location close to the aircraft. Accordingly,... --- - Published: 2025-02-10 - Modified: 2025-07-01 - URL: https://sharetree.co.uk/universal-gearbox-testing-chamber/ - Categories: Uncategorised Gearboxes for vehicle steering systems are an essential component whose reliability must be tested under a wide range of environmental conditions (+120 to –40°C is not uncommon). Realistic testing requires that gearboxes are connected to other mechanical assemblies and then operated. To perform such testing under controlled conditions, the gearbox must be inside an environmental chamber, but the position and angles of the input and output drive shafts are highly variable for different gearbox designs. This difficulty has often led to bespoke chambers being constructed for each specific model of gearbox, a costly and inefficient approach for a gearbox manufacturer or test laboratory. However, using a generic chamber poses a considerable challenge in achieving a wellsealed and therefore precisely controllable atmosphere for testing. Sharetree works extensively with companies in the automotive and oil/gas industries with a need to rigorously test such mechanical devices, and so they decided to design and build an environmental chamber which would be quickly and easily configurable to fit a whole range of gearboxes. Where thermal and mechanical processes meet The concept of the gearbox testing assembly was a ‘box within a box’ – a small safety enclosure in which the configurable chamber for the gearbox under test was located. The safety enclosure contained the mechanisms to drive, and be driven by, the gearbox. The gearbox test chamber was connected to two large air ducts, used for circulating air between the chamber and the adjacent air conditioning unit (ACU) that would provide the temperature control for... --- ---
