Original abstract
This paper tackles various specific issues related to professional laundry care process. Design of efficient system of heat recovery in professional laundry is conditioned by successful management of these specifics. The paper also gives several suggestions for the design. Measurement method including original software for data processing was designed for more efficient acquisition of humid air parameters in outlet stream from drying equipment (i.e. dryer, ironer, tunnel finisher). These parameters are relevant for determination of the amount of applicable waste heat and its time course. This method has minimum impact upon equipment operation and its technical readiness to measure and is thus suitable for irregular measurements in laundry facilities. The paper also presents case study of heat exchanger design for heat recovery based on requirements from real laundry operations. Plate-type air-air heat exchanger preheats drying air for tumble dryers while using waste heat from tunnel finisher.
Czech abstract
Článek se zabývá specifickými problémy, které je nutné řešit, aby bylo možné navrhnout efektivní systém rekuperace tepla v rámci procesu profesní údržby prádla. Kromě popisu jednotlivých problémů článek obsahuje i několik doporučení pro návrh rekuperačního systému. Článek představuje také metodu pro sběr a zpracování provozních dat, která mají pro návrh systému zásadní význam. Metoda je založena na měření parametrů vlhkého vzduchu na výstupu ze sušicích zařízení (tj. sušič, žehlič, tunelový dokončovač) a má minimální vliv na provoz zařízení a jeho technickou připravenost na měření. Prezentovaná případová studie ilustruje využití deskového tepelného výměníku typu vzduch-vzduch pro získávání odpadního tepla z tunelového dokončovače pro předehřev sušicího vzduchu pro bubnové sušiče. Studie vychází z potřeby skutečného prádelenského provozu a staví na naměřených provozních datech.
