The use of air source heat pumps (ASHP) in the specific context existing multi-family buildings (MFB) represents an important challenge, especially terms performance and technical constraints real conditions use. This study concerns actual two non-retrofitted MFB (4047 7563 m2), whose original fossil supply was replaced by a centralized monovalent (2 × 156 kW) hybrid (6 34 ASHP system for space...

Low air temperature and frosting have been reported as the critical factors that greatly attenuate efficiency performance of ASHP in cold regions. In order to ensure potential prevalence regions China, a new ultra-low unit was developed, field measurement carried out an office building where these units were installed Shanxi Province. Results showed coefficient (COP) 1.83 obtained at environmen...

In the Canadian north, cost of space heating is very high due to harsh weather, its remoteness, lack transportation, and dependency on fossil fuel imported from South. Since North has an abundance solar energy, significant energy savings with some added construction in houses could be achieved by applying high-performance building envelopes design strategies. The objective this paper investigat...

Background: Stress-related mucosal disease (SRMD) frequently develops in critically ill patients, increasing mortality and length of intensive care unit (ICU) stay. There is limited data on stress ulcer prophylaxis (SUP) patients Indonesia.Objective:Methods: This a retrospective cohort study admitted to the ICU from January 1, 2015, December 31, 2017. The subjects were all who used proton pump ...

The simultaneous need for energy efficiency and indoor comfort may not be met by existing air source heat pump (ASHP) technology. novelty of this study lies in the use a new gravity-driven radiator as heating terminal ASHPs, aiming to provide an acceptable with improved efficiency. To confirm quantify performance improvement due proposed system retrofit, field test was conducted examine under r...
