Working principle and Advantage of High temperature air source heat pump dryer
      Working principle  The air source High-temperature heat pump dryer adopt reverse carnot principle to absorb the heat of air and transfer it to the room, to increase the temperature of drying room, to achieve the drying of materials article.  It consists of compressor-heat exchanger-Electric expansion valve(throttle)-Evaporator constitute a circulation system.The refrigerant circulates in the system under the action of compressor, It completes the gaseous boosting process in the compressor (temperature up to 100 °C), it enters the internal machine to release high-temperature heat to heat the air in the drying room, while being cooled and converted into a liqu
The Belt and Road Initiative offers exciting prospects for the HVAC market
The Belt and Road Initiative offers exciting prospects for the HVAC market
      Unveiled in the autumn of 2013 by the Chinese government, the Belt and Road Initiative has attracted participation by more than 100 countries and international organisations since its implementation. Over 40 of these participants have signed cooperation protocols with China outlining the broad sense of international collaboration which has been established.  There are many developing countries along the route of the Belt and Road where basic infrastructural development is in great demand. HVAC, being one of the key elements of infrastructure, is therefore crucial to the livelihood of the residents along the route. The implementation of the Belt and Road Initiativ
Common sludge drying process
Common sludge drying process
      Industrial production and people's daily lives always produce sewage, and the pressure of sewage treatment is not small. The current mainstream method is to dewater and dry the sludge obtained after sewage treatment (high water content), and to concentrate the sludge after drying, incinerate or landfill.  The disposal organization has requirements for sludge. A hard indicator is the water content. The sludge with insufficient moisture content is likely to cause potential damage whether it is incinerated or landfilled. At the same time, reducing the water content reduces the total sludge for enterprises. It is also important to reduce the cost of disposal.  
What is the best choice of the terminal device for the air source heat pump?
What is the best choice of the terminal device for the air source heat pump?
    The working principle of the air source heat pump is to absorb the low temperature heat in the air. In the whole heating process, electricity is only auxiliary energy. It is 400% energy saving higher than the electric water heater. The air source heat pump is regarded as the new generation of environmental friendly energy saving equipment after the solar energy. It achieved great success in the "coal to electricity" project in the northern province, and was unanimously recognized by users. The terminal devices of the air source heat pump mainly include floor heating, radiators, and fan coils. Which one is more advantageous
What Is The Screw Type EVI Air To Water Heat Pump For Heating
What Is The Screw Type EVI Air To Water Heat Pump For Heating
    Dual core screw type EVI air to water heat pump unit adopts dual core screw type compressors in one unit. Dual core EVI technology is designed to break through the traditional extremity of application, to fulfill higher output temperature, to work at lower ambient temperature. The COP could reach 2.2 at -30 degree ambient temperature, which is a revolutionary technical breakthrough for EVI heating system. So what are the advantages of dual core screw type EVI heat pump for heating compared with the normal EVI air to water heat pump for heating? Fearless of Severe ColdDual core EVI Screw Type Air To Water Heat Pump unit adopts dual core screw type compressors in o
How do Heat Pumps Work?
How do Heat Pumps Work?
    All heat pumps use the principle of Boyles law – that the temperature and vapour pressure of a substance are directly and proportionately related at a constant volume.Boyles Law: PV/T = constantWith most heat pumps the overall heat pump itself has a fixed volume hence as pressure is changed the temperature changes proportionately and vice versa.The Vapour Compression CycleBy far the most common form of heat pump uses a vapour compression cycle and hence has some form of compressor installed in the circuit which is most usually powered by electricity but can be driven by a gas internal combustion engine.Gas Absorption Heat PumpsThese use the principle of applying heat –
What is a Heat Pump?
What is a Heat Pump?
    It does just what it suggests, it pumps heat, taking energy from a (relatively) low temperature source and forces that heat to a higher temperature making it more useful. It is analogous to a water pump which raises water from low level to a higher level, a heat pump does the same – but with heat! This diagram is purely illustrative of the effect of a heat pump and not its operation.Even ice still has some heat energy, in fact energy is always present until the value of "absolute zero" is reached some –273.16°C, which is why the Kelvin scale has its start point at absolute zero (and hence freezing point is +273.16 Kelvin).We should all be familiar with
