EVI Heat Pump Features

Overview of EVI Heat Pump


EVI air source heat pump for the supply of less than -25 ℃ environments for use. In many countries are commonly used EVI air source heat pump as a way of winter heating, especially in the relatively cold environment, EVI air source heat pump more widely. Low-temperature air to heat the biggest advantage is that in the Arctic environment can still be efficient heating, the traditional room temperature heat pump system, in the face of low-temperature performance challenges, the unit's safety and reliability are often greatly reduced.  By injecting the refrigerant directly into the SCROLL compressor head, the conditions in the refrigerant circuit of the system change. As a result, the heat pump outlet temperature reaches a low temperature of up to 60 ° C even at low ambient temperatures. Another advantage is the lower heat loss and the efficiency with decreasing source temperature.

EVI Heat Pump

EVI Air Source Heat Pump Components


  • A. Compressor(scroll)

    With the Copeland scroll compressor, the EVI heat pump would have a high heating capacity, longer service time and to be more stable.
  • B. Refrigerant(R410a)
    Adopting the environmental R410A refrigerant and circulating heating method, RONRUI EVI Heat Pumps are able to keep its COP as high as 4.4 at 20°C ambient temperature and COP 3.4 at 7°C.
  • C. Reliable and High Efficient Heat Exchanger

    The unit uses patented tube and shell heat exchanger which is with high efficiency and can be widely applied for cooling and heating.
  • D. Valve

    The expansion valve in the low temperature air source heat pump can be thermostatic with statically adjustable superheating or electronic. The signal from the electronic temperature sensor is used to open and close the discharge opening. This allows the superheat to be set more accurately and controlled over a wider range of condensation and evaporation pressures.
  • E. Plate heat exchanger
    Plate heat exchanger
    a)The original unique evaporator which can be applied to various refrigerants can be allocated variable technology.

    b)The original unequal volume medium channel drainage technology is a uniform distribution of various media in the channel, and the heat transfer efficiency is higher.

    c)Full set of automatic production and testing lines, strict testing and pressure and leakage testing, so that product quality safer, stable and reliable.

    d)Compared with traditional brazed plate heat exchangers, the heat transfer performance is improved by 10%-25% or even higher.

The Advantages of Low Temperature Air Source Heat Pump

Products:

A. Low operating costs
low-temperature air source heat pump can save the whole year 1/3 of the cost, while full use of low-temperature hot water resources, no need to add another air energy water heaters, also reduced the cost of running.

B. Comfortable
You can feel the EVI air heat pump to bring comfort and comfort experience. Whether you are from the living room to the bedroom, or from the bedroom to the bathroom, the temperature of each region is basically the same, to avoid the case of hot and cold, to ensure that indoor temperature 21 ℃. At the same time, the temperature is from bottom to top to spread the heat, the body will feel the foot to the knee position or warm up, below the body warm, people naturally feel warm up.

C. Installation is flexible
EVI air source heat pump to meet part of the heating family due to the transformation, replacement of heating equipment lead to the end of the situation is not suitable. Can be used with a radiator, with easy installation, easy maintenance and other advantages, as long as the air circulation can be installed on the ground. Install smart, convenient, really do not want to install which installed, completely free from external factors such as impact.

D. Energy efficient
EVI air source heat pump heating method of high thermal efficiency, heat concentrated in the human body to benefit the height of the transmission process of heat loss.

E. Long service life
EVI air source heat pump is buried through the underground pipe, good stability, no corrosion, no man-made damage, life and building synchronization. Relatively convection heating maintenance and replacement costs.

F. High COP
Adopting R410A refrigerant and circulating heating method, RONRUI EVI Heat Pump is able to keep its COP as high as 4.4 at low ambient temperature.

G. Water Temp. up to 60°C
Thanks to EVI technology, our EVI heat pump series features a wide operating temp. range. It means they can reach high water temp.(55-65oC) even in cold climate ranging from -25°C to 45°C, and can work safely and reliably at ambient temp. as low as -25°C with Wet Injection technology.

Company:


A. Many parts of the products are produced by ourselves which could cut cost and make the prices competitive.

B. With many advanced testing equipments and professional quality inspectors, the quality of our products could be guaranteed.

C. We have professional designers and engineers, and OEM/ODM service is available for us!

FAQ of EVI Heat Pump
  • Q: Does an Air Source Heat Pump make a lot of noise?
    A: An Air Source Heat Pump will make some noise when they are operating, as a compressor and fan are in motion, however, this noise can be far less than you may think. Before an Air Source Heat Pump can be installed they must also pass a noise assessment, ensuring you will never hear the Heat Pump from inside your property.
  • Q: Where is heat pump using?
    A:  Because Air source heat pump save energy around 70 %, ( EVI heat pump and central cooling & heating heat pump ) is widely used in home heating, hotels hot water & heating, restaurants, hospitals, schools, bath center, residential central heating and hot water plants, etc.
  • Q: What does RONRUI New Energy company do?
    A:  RONRUI New Energy is professional in various kinds of heat pumps and wine coolers.
  • Q: What is the package of the products?
    A: Strong wood box plus carton box.
  • Q: Where are the RONRUI New Energy heat pump export to till now?
    A: Currently the products have been exported to Western Europe, North Europe, South Africa, Middle-East, South American and Australia market.
  • Q: Is OEM/ODM available for your company?
    A: Yes, both are available for us!
  • Q: How long is your EVI & DC Inverter Split Heat Pump delivery time?
    A: Generally it is 1-5 working days if the goods are in stock. Or it is 15-25 working days if the goods are not in stock, it is according to quantity.
  • Q. Why are Heat Pumps better than other forms of heating?
    A: Heat pumps are much cheaper to run giving up to 4 times more heat than you pay for, they can be used all year round for both heating and cooling. Heat pumps produce low-density heat which is safe for children and the elderly, unlike fires or electric heaters. They are unmatched for convenience and easy to use (Remote Controlled). They don't pollute our atmosphere as with products for combustion and they use ozone-friendly refrigerants.
