Features of EVI air to water (air source)heat pumps:
The working principle of the ultra-low temperature EVI jet enthalpy technology is similar to that of the turbocharged engine of the car, which can greatly improve the heating capacity of the heat pump unit and effectively expand the operating range of the unit. This technology replaces boiler coal-fired heating, reduces air pollution, reduces smog, and operates stably in low-temperature environments as low as -20°C, so that air energy (source) heat pump units can significantly increase the amount of heat produced in low-temperature environments in northern regions. With the inverter compressor, the heating capacity can be increased by as much as 45%. The operating cost is reduced by more than 70% compared with the traditional heating method, and it can be successfully used in the fields of air conditioning, freezing and refrigeration, and domestic hot water4. It solves the technical problems of poor low-temperature heating effect and insufficient energy efficiency that have plagued the entire air-conditioning industry for many years. , Become a reliable choice for heating in cold areas
EVI air source heat pumps are designed for domestic/commercial hot water and house heating in cold areas where lowest air temperature is above -25℃.
1. The evaporator adopts a window-opening design, which has a better evaporating effect and more energy-saving compared to a straight fin design!
2. The compressor adopts Panasonic high-efficiency rotor compressor, which has higher energy efficiency and lower noise
3. The electric control increases the use of current transformer protection, which will protect the compressor when the current is large, effectively protecting the compressor, and greatly reducing the possibility of burning the compressor!
4. The fan blades are designed with a large inclination angle, and the noise is low, ensuring that the noise of the machine at night will cause sleep disturbance to the user!
5. Adopting enhanced frost design, specifically for high-humidity areas, quickly defrosting.
6. The system adds a liquid storage and return tank, which can effectively ensure the oil return of the compressor and reduce the malfunction caused by the lack of oil of the compressor!
7. The chassis is heated, drained and heated, so that the condensate and defrosted water can be drained smoothly in winter!
8. R410a refrigerant is environmentally friendly, more energy efficient, and has better low temperature energy efficiency. Generally, R22 refrigerant equipment is used
9. The AC contactor uses Schneider silver contacts, which will not produce sparks when it is closed, and is durable!
10. The capillary shunt is protected by heat shrinkable heat insulation, which can be insulated and can reduce the friction between the capillaries!
11. There are 0.5 mm and 0.75 mm oxygen-free copper pipes from underground capillary copper pipes for your choice!
12. In terms of models, Fuxin Air can have a room temperature engine, and the EVI jet enthalpy (add air enthalpy) engine has 30% higher heat capacity and 16% energy saving than the room temperature mechanism. It adopts dual electronic expansion valves and plate heat exchangers ( Economizer) can be used in low temperature environment (can be used normally at -30~25 degrees).
Features of EVI system structure:
(1) It is necessary to use a compressor with a supplementary air port, otherwise it will be difficult to achieve enhanced supplemental air technology;
(2) Add an economizer (subcooler or flasher) to the conventional system, and spray gaseous refrigerant into the compressor;
(3) Add a throttling device to achieve secondary throttling. The economizer has two important functions here: one is to pre-cool the refrigerant in the main circulation circuit before throttling, so as to increase the refrigerant enthalpy difference; but to perform throttling on the refrigerant in the auxiliary circuit. Appropriate gas-liquid separation to reach a suitable intermediate pressure (higher than the pressure at the compressor inlet), so that the refrigerant does not enter the evaporator to absorb heat, and directly participates in the compression process of the compressor.
