FAQ’s Related to Heat Pumps Heat pumps use an average of 75% of heat from environment and 25% energy for the operation (generally electricity, possibly gas, but with different output) to produce 100% usable heat for space heating and hot water production. Environmental heat is accessible everywhere. In air, water and ground are stored huge amounts of energy that continuously regenerates naturally from solar radiation, rainfall and heat from the earth's core. Air source heat pumps - Ambient air is available anywhere and is unlimited, so it can serve simple as a heat source. Using this heat is free and requires no special formalities (building permit). Air/water heat pumps yield the heat generated through a conventional heating system with hot water (radiators or underfloor heating system) and the air/air heat pumps towards a hot air circulation system. Ground source heat pumps (geothermal energy) - Natural energy stored in the earth can be used through a simple process: with vertical geothermal wells that reach depths up to 300 meters. There are variants for using ground energy: thermal poles or thermal beams. Common to these systems is that on the heat source part they are closed systems. Meaning, in the underground there is no substance exchange, only heat exchange. An installation in the ground can be also used for space cooling. Water source heat pumps – Ground water has a temperature almost constant during the entire year that is why it is an optimum heat source for a heating installation with heat pump. But surface water from lakes and streams, can also be used as a heat source. Such an installation can be also used for space cooling. The amount of heat extracted from surface waters or groundwater is immediately regenerated by natural circulation of water. Other questions refer to proportion of renewable energy for heat pump use, combination possibilities between heat pumps and solar systems, the efficiency of heat pumps, using heat
pumps in combination with radiators, electricity consumption.
Artifex - state of the art on energy efficiency in the textile industry Jetrun EnergoEco commissioned the HVAC equipment at Artifex, a textile manufacturing plant in Focşani, Romania In 2012 , Artifex started the total renovation of a 13 500 m2 working space, located in Focsani. The production process involves various types of activities, each activity requiring a different microclimate . A common essential element is the need for a strict control of the humidity level. The client wanted a system that provided energy efficiency and a high level of comfort for the employees, which became a challenge for the whole team who worked on the project: the design company Cepronef, the execution company Amteh and the equipment supplier Jetrun EnergoEco.
employees, it is important to ensure a consistent volume of fresh air without affecting the overall efficiency of the installation. The heat recovery system benefits from a special treatment to ensure humidity recovery from the spent air, an extremely important function to reduce the need for additional humidification in winter. As for increased comfort for the employees, we opted for underfloor heating and cooling. By reducing the heat and cooling load of the ventilation system, we can reduce the difference in temperature between the introduced fresh air and the air inside the room, thus eliminating the discomfort created by conventional systems for heating / ventilation. The air introduction piping was made up of textile fabric and the exhaust air system was made up of metal. To ensure the thermal load for heating and cooling, Jetrun delivered 4 reversible geothermal heat pumps of 250 Kw each, with multiscroll technology and intelligent cascading kit, produced by Hiref. The heat pumps extract heat from a geothermal field of 120 wells of 120m depth and cover the entire heat demand of the building. At a COP 4.0, the primary energy
„The project requirements regarding energy consumption is reduced 4 times compared to a efficiency and a high level of comfort have standard system. increased the complexity of the system and asked for a creative approach. We opted for implementing a geothermal heat pump solution, creating one of the largest industrial projects that use geothermal energy in Romania. We decided to follow the operating parameters of the system to develop a Flue Gas Analyser EUROLYZER ST/e, 4 years warranty practical knowledge base in this area which is AFRISO is the world's first manufacturer to use lead-free O2 sensors (ECO sensors) in the less explored in our new EUROLYZER ST/e flue gas analyser. The analyser features the most advanced sensor country”, said Adrian technology; the ECO sensors excel not only with extremely fast calibration and response times, Moisa, general but also with a long service life (anti-aging compensation). The new measuring instrument manager at integrates QA mean value measurement as per the amendment to the 1st German Federal Jetrun. Immission Control Act, which improves the evaluation of furnaces in the case of heavily fluctuating The ventilation flue gas losses. The device is suitable for measurements of oil, gas and pellets fired systems as well as system is CHP systems and for inspecting heating systems for CO leaks. The ergonomically designed measuring made up of 4 instrument is contained in a robust protective sleeve with integrated magnets. Its large bright colour air handling display provides excellent readability and shows two different levels for measurements, if required. A units Wolf KG touchpad is provided for intuitive operation, which is further simplified by colour-coded menus and Top 510 of colour-coded measured values (green/flue gas, blue/temperature, yellow/pressure). Depending on the 40,000 m3 / equipment options and on the configuration, the device can be used for a heating system check and a h with rotary 4 Pa test as well as calculate and display the following parameters: Gas analysis (O2, CO, CO2, NO, NOx), heat recovery temperature/pressure measurement, differential pressure, draft, efficiency, excess air and automatic system and KG pressure drop. Data transmission interfaces comprise Bluetooth and USB; Bluetooth is also used Top 190 of 10,000 for communication with pressure and temperature probes. A standard MicroSD card allows for m3 / h with plate system-independent data storage. An infrared interface for the EuroPrinter allows the user to heat recovery . Given create printed records of the measurement directly at the customer's site. A powerful NiMH the high density of battery provides up to 10 hours of service time in Eco mode.
