“…The PMV predicted well the real thermal sensation in [21,69], whereas in the other studies, the PMV was somehow unable to accurately measure the actual mean vote reported by people. Thus, 10 out of the 12 studies concluded that, in some way, PMV was not suitable, either overestimating or underestimating when applied in hospital environments.…”

Thermal Comfort Applied in Hospital Environments: A Literature Review

2020

The predicted mean vote (PMV) is the most widely used model around the world to assess thermal comfort in indoor environments. The year 2020 marks the 50th anniversary of the PMV model and also the year in which the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic. In this context, hospital environments and health professionals are at the center of attention, and a good indoor environment for those professionals to develop their activities is essential. Thus, considering the PMV model and focusing on hospital environments, this study performed a literature review of studies published between 1968 and August 2020. The research identified 153 papers on thermal comfort and its application in hospitals, health centers, and elderly centers. Specific inclusion and exclusion criteria were adopted to determine the most relevant studies for the four research questions proposed in this study. After applying the exclusion criteria, 62 studies were included in order to identify their main characteristics. In the universe of the 62 studies, this review identified 24 studies that applied the PMV model and 12 where there was a comparison of PMV and the thermal sensation votes (TSV) reported by people. The main findings of this research are: (i) A good thermal environment for professionals and patients is important, and more studies are needed; (ii) there are little explored topics, such as productivity related to thermal comfort in hospital environments; (iii) in addition to thermal comfort, other indoor environmental quality (IEQ) parameters have also been evaluated, such as indoor air quality (IAQ); (iv): the COVID-19 pandemic has highlighted how the quality of indoor spaces is important in order to ensure occupant’s health.

“…Thermal comfort, energy efficiency, and air quality in hospitals are issues that are closely related. For an organization, it is important to plan the operation of HVAC systems in the short term and make long-term decisions regarding automatic control systems or expert operators, in order to obtain direct benefits by reducing energy consumption (thermal and electrical) and indirect, by improving working conditions such as the risk of spreading diseases in patients and workers, as well as in the planning of energy investments (coatings and thermal insulation, installation or repair of HVAC systems) [32,[43][44][45].…”

There is a need to ensure comfortable conditions for hospital staff and patients from the point of view of thermal comfort and air quality so that they do not affect their performance. We consider the need for hospital employees and patients to enjoy conditions of greater well-being during their stay. This is understood as a comfortable thermal sensation and adequate air quality, depending on the task they are performing. The contribution of this article is the formulation of the fundamentals of a system and platform for monitoring thermal comfort and Indoor Air Quality (IAQ) in hospitals, based on an Internet of Things platform composed of a low-cost sensor node network that is capable of measuring critical variables such as humidity, temperature, and Carbon Dioxide (CO2). As part of the platform, a multidimensional data model with an On-Line Analytical Processing (OLAP) approach is presented that offers query flexibility, data volume reduction, as well as a significant reduction in query response times. The experimental results confirm the suitability of the platform’s data model, which facilitates operational and strategic decision making in complex hospitals.

“…Several thermal comfort studies have directed that six major parameters affect "human thermal comfort, " in which the factors have been classified into two categories such as environmental and individual or personal [5][6][7][8][9][10]. Similarly, "psychological parameters, such as individual expectations, also affect thermal comfort" [11].…”

Railway transportation plays a significant contribution to carrying passengers in India. In which during the journey, pantry cars are involved to serves the food to all onboard passengers. The kitchen atmosphere of the pantry car gets very hot and humid during cooking which could affect occupants' thermal comfort. Therefore, the current research article describes a review of the factors affecting human thermal comfort inside the kitchen of the railway pantry car. The factors influencing of human thermal comfort inside pantry car kitchens are classified into two categories viz; environmental factors that include "air temperature, mean radiant temperature, relative humidity, air velocity" and personal or individual factors including "metabolic rate and clothing insulation". All these factors need to be considered in order to achieve the optimum level of thermal comfort inside the kitchen environment of the pantry car. With the assistance of all these factors, we can estimate the thermal comfort indices such as; SET "standard effective temperature, " PMV "predicted mean vote, " PPD "predicted the percentage of dissatisfied, " thereby recognizing the acceptable thermal sensation range for occupants' (chefs) in the pantry car kitchens during the work period. These kinds of parametric studies can cover a wide group of all pantry car chefs in evaluating thermal comfort. Furthermore, there is a need to apply all the consequences of this research to increase the chef 's thermal comfort inside the pantry car kitchen while working.
