Pompa adalah peralatan mekanis untuk meningkatkan energi tenakan pada cairan(fluida) yang dipompa dengan mengubah energi mekanis poros penggerak menjadi energi potensial dan energi kinetis fluida. Seiring berkembangnya teknologi, pompa digunakan diberbagai bidang termasuk pemakaiannya dalam bidang indsutri. Pompa Sentrifugal merupakan salah satu jenis pompa yang mempunyai lingkup penggunaan yang sangat luas terkait dengan head dan kapasitas yang dihasilkan. Pada kesempatan ini penulis mencoba memaparkan hasil penelitian tentang unjuk kerja pompa sentrifugal bila dilakukan variasi tinggi hisap pada pompa sentrifugal akan mempengaruhi kapasitas, Head, Daya Hidraulis dan effesiensi pompa sentrifugal. Variasi tinggi hisap dimaksudkan untuk mengetahui peningkatan performance pompa yang terjadi akibat penambahan tinggi hisap pompa. Menambah tinggi hisap pompa sangat berpengaruh terhadap kapasitas aliran air yang dihasilkan, hal ini juga akan mempengaruhi kerja pompa, kecepatan spesifik, daya dan efesiensi pompa. Sehingga dapat diperoleh titik kerja tertinggi pompa sentrifugal dengan Kapasitas (Q) 0,001180 m3/s, Head (H) 6,066 m, Daya Hidraulis (Ph) 70,008 watt, Effesiensi (É³p) 26,51 %, hal ini dapat terlaksana bila diikuti penambahan daya dari motor penggeraknya.

“…On the other hand, a comprehensive review conducted by the authors of [31] (covering studies from 2016 to 2022) highlighted the potential advantages of hybrid systems. The authors of [32] noted that the energy and economic efficiencies of these systems vary considerably due to the control strategies employed and the chosen objective functions.…”

Hybrid heat pump (HHP) represents a heating system (HS) that simultaneously utilises two or more energy sources. The key novelty is the integration of an optimised control strategy, effectively maximising the efficiency of both the heat pump and gas boiler segments. In this study, a HHP system that consists of an air-source heat pump (ASHP) and a condensing-type gas boiler (GB) for a two-story single-family house was calculated and validated. The results from three different calculation methods were obtained: the heat pump manufacturer’s calculator, the simulator programme, and the calculations based on real measured data. Two operation modes were tested: economic mode, where the cheapest energy resource becomes the priority, and ecological mode, where the system operates using the energy resource with lowest CO2 emissions. When comparing consumed energy, there was a 15.36% variance between the manufacturer’s program and the actual measured data, while for produced energy, the difference amounted to 25.81%. It was found that the balance point temperature is −7 °C, where the heat pump unit of the HHP system can cover necessary heat losses until that point, while the gas boiler operates at lower temperatures. Changes in electricity price can significantly influence the point of the system switch, but the possibility to cover heat loads of the heat pump unit always has to be taken into account.

“…Collecting data and developing models to predict occupant behavior is the next step in sustainable design [7][8][9][10][11]. Hybrid heating systems based on the use of an air or ground heat pump (HP), photovoltaic panels, and an additional peak heat source (e.g., gas boiler) are becoming more and more popular [12][13][14][15][16][17][18]. The supplemental element of the hybrid system is also air-type HP dedicated to DHW heating.…”

This study evaluates a hybrid heating system in a single-family building in northeastern Poland, which has a temperate continental climate. The analysis covers two heating seasons in 2021/2022 and 2022/2023. The hybrid heating system includes an air heat pump HPA–08 CS Plus with a heating power of 8.2 kW (AHP), a condensing gas boiler VC146/5–5 with a power of 14 kW (GB–Condens.), and a solid fuel boiler with a power of 11 kW for central heating. Additionally, hot water is heated by a Basic 270 (DHW’s AHP) air–water heat pump with a power of 2 kW, utilizing a tank with a capacity of 270 dm3 equipped with two heating coils. The building’s average electricity consumption is around 5400 kWh/year. A 4.96 kWp photovoltaic installation is installed on the building’s roof at a 40° angle towards the south to supplement the hybrid system. The study aims to assess whether the PV installation can adequately cover the energy needs of the hybrid heat source for heating and hot water. Furthermore, the study calculates the emission of pollutants (CO2, SOx, NOx, CO, and PM10) into the atmosphere. The total annual electricity production from PV installations was 5444.9 kWh in 2021/2022 and 5684.8 kWh in 2022/2023. The excess electricity was stored in the PGE power grid as per the Prosumer settlement rules. The installed PV installation is sufficient to power the following devices annually: AHP, DHW’s AHP, and GB–Condens. However, the daily electricity production from the PV installation is not enough to cover the energy needs of the heat pump for heating during the cold months in Poland (I–III, XI–XII). It can meet the power needs of a PC all year round and can also be stored during the summer months, for example, in energy warehouses or by directly storing it in the PGE power grid. The use of the PV installation resulted in an average reduction in pollutant emissions into the atmosphere: CO2—94.1%, SOx—91.8%, NOx—95.6%, CO—9.7%, and PM10—32.1%.
