The temperature in the northern part of our country is relatively low in winter, so almost all air conditioners will lose the ability to make heat, and heating must rely on coal and gas as the main heat source for heating. However, the emergence of air energy heat pump has changed this situation, the use of air energy heat pump can also realize fan panel control heat (with floor heating and radiator can also be used), air energy heat pump absorbs low-temperature heat energy in the air through the role of environmentally friendly refrigerant, after heat pump compressor processing, can produce high refrigerant steam, so as to exchange heat into indoor circulating water, and finally realize indoor heating. Under normal circumstances, air energy heat pumps are divided into normal temperature type and low temperature type, and the EVI jet enthalpy increasing technology is added, which greatly improves the heating capacity of the low temperature air energy heat pump, and can start operation even in a low temperature environment of -25.
What is Jet Enthalpy Enhancement Technology?
Jet enthalpy enhancement is a new type of system composed of jet enthalpy enhancement compressor, jet enthalpy enhancement technology, and high-efficiency supercooler. The economizer formed by the high-efficiency jet enthalpy booster compressor, the high-efficiency supercooler and the electronic expansion valve and the high-efficiency heat exchanger together constitute a high-efficiency and energy-saving jet system.
The jet enthalpy booster compressor adopts two-stage throttling intermediate jet technology and uses a flash evaporator for gas-liquid separation to achieve the enthalpy enhancement effect. It is mainly cooled by mixing and cooling while compressing while jet at medium and low pressure, and then compressing normally at high pressure to increase the discharge capacity of the compressor and achieve the purpose of heating capacity in low temperature environment. Among them, the high-efficiency supercooler also plays a key role in the whole system, on the one hand, the main circulation circuit refrigerant is subcooled before throttling, increasing the enthalpy difference; On the other hand, the low-pressure and low-temperature refrigerant in the auxiliary circuit is properly preheated after being depressurized by the electronic expansion valve to achieve a suitable medium pressure and provide it to the compressor for secondary compression.
What are the core advantages of air energy heat pumps?
The working principle of air energy heat pump is similar to that of ordinary air conditioners, which can meet the needs of cooling in summer and heating in winter, the difference lies in the difference in their respective pertinence and application conditions. **Air conditioning is mainly refrigeration, taking into account the heating function, but the heating capacity is insufficient under low temperature conditions, and some units have to rely on electric auxiliary heat to do work at 0, when the temperature is as low as -5, many ** air conditioners have struck. The air energy heat pump is mainly used for heating, and the refrigeration function will be stronger, and the heating is still close to 3 at -120 high energy efficiency ratio, can still operate normally at -25 (some low-temperature air energy heat pumps break through the technical barrier and can operate at a low temperature of -35).
