The purpose of jet enthalpy technology
To understand the jet enthalpy increase technology, we must clarify the purpose of this technology: it is to solve the problem of low temperature heating.
The air conditioner extracts heat from the outdoor air in winter and sends the heat to the room. This is the heating principle of the air conditioner! The jet enthalpy increase technology is to strengthen this heat extraction process, so that more outdoor heat is sent to the room.
The principle of jet enthalpy technology
The design concept of jet enthalpy increase technology is somewhat similar to the "turbocharging" of a car. It is based on the air jet enthalpy increasing compressor, and optimizes the refrigerant injection technology in the medium pressure section. It sucks in a part of the intermediate pressure gas through the intermediate pressure suction hole, and mixes it with the partially compressed refrigerant for recompression, realizing the realization of a single compressor. The two-stage compression increases the refrigerant flow in the condenser and increases the enthalpy difference of the main circulation loop, thereby improving the efficiency of the compressor.
In addition, the jet enthalpy increase system is a low-temperature and strong heat-mediated compressor, and several key components such as a radiator, a low-temperature one-way solenoid valve for heating, a one-way solenoid valve for heating, and a high-heat heat radiator are added. Part of the refrigerant directly After the compressor increases the enthalpy, it is equivalent to supercharging, so as to increase the heating capacity.
"Three Major Items" of Enthalpy Increase by Jet
It is actually a combination of three items: jet enthalpy compressor, jet enthalpy technology, and high-efficiency subcooler. The new system composed of these three items is an organic whole, which can provide high-efficiency performance, meet the normal and efficient operation of the air conditioner at low temperature, and allow the air conditioner to heat quickly and stably even at low temperature.
1. Jet enthalpy compressor
The jet enthalpy increasing compressor adopts two-stage throttling intermediate jet technology, and uses a flash evaporator for gas-liquid separation to achieve enthalpy increasing effect. It compresses and mixes with air at medium and low pressure, and then compresses normally at high pressure, so as to increase the compressor displacement and improve the heating capacity in a low temperature environment.
2. High-efficiency supercooler
The high-efficiency subcooler also plays a key role in the whole system. On the one hand, it supercools the refrigerant in the main circulation circuit before throttling to increase the enthalpy difference; The low-pressure and low-temperature refrigerant that is introduced into the direct compression) after being depressurized by the electronic expansion valve is properly preheated to reach a suitable medium pressure, and is provided to the compressor for secondary compression.
3. Air jet enthalpy increase technology
The compressor of the jet enthalpy technology has an additional suction port, which cools the refrigerant in the main cycle by generating steam. The steam enters the compressor from the second suction port. Quasi-secondary compression process. The jet reduces the exhaust gas temperature, reduces its exhaust superheat, reduces the length of the gas-phase heat exchange area of the condenser, increases the two-phase heat exchange area, and improves the heat exchange efficiency of the condenser. The better the effect, so the effect is more obvious in the low temperature environment.
