Heat pump air-conditioning system based on jet blowing

Abstract

The invention discloses a heat pump air-conditioning system based on jet blowing. The heat pump air-conditioning system comprises a compressor, a four-way reversing valve, a first jet blowing device, a first heat exchanger, an expansion valve, a second jet blowing device, a second heat exchanger and a gas-liquid separator, wherein the compressor is respectively connected with the four-way reserving valve and the gas-liquid separator; the four-way reversing valve is also connected with the first heat exchanger, the second heat exchanger and the gas-liquid separator; the first heat exchanger is connected with the expansion valve; the expansion valve is connected with the second heat exchanger; after air is turbocharged by the first jet blowing device, the air jets and flows into the first heat exchanger; after the air is subjected to heat exchange treatment by the first heat exchanger, the air flows out of the first heat exchanger; after the air is turbocharged by the second jet blowing device, the air jets and flows into the second heat exchanger; and after the air is subjected to heat exchange treatment by the second heat exchanger, the air flows out of the second heat exchanger. According to the heat pump air-conditioning system disclosed by the invention, the energy source utilization rate of the system can be improved and system noises are reduced.

Description

technical field [0001] The invention relates to air conditioning technology, in particular to a heat pump air conditioning system based on jet air supply. Background technique [0002] With the continuous improvement of people's living standards, in the living and indoor working environment, through the installation of air-conditioning systems to improve the comfort of living and working environments, it has become an important choice for people to improve comfort needs, and among them, the use of more The air source heat pump air conditioning system. [0003] The existing air source heat pump air conditioning system generally exchanges heat between the refrigerant in the heat exchanger and the surrounding air, absorbs heat from the air to cool the air, or releases heat to the air to heat the air, thereby evaporating or condensing the refrigerant. The cooled or heated air is then sent into the room or exhausted into the atmosphere. [0004] In the above-mentioned heat exch...

Problems solved by technology

Among them, for outdoor units, for heat exchangers with different cooling capacities, motors with corresponding power need to be matched, and the blades of the impeller need to be specially optimized, which leads to high cost. As a result, the air velocity flowing through the heat exchanger is low and the air supply distance is short; moreover, the blades in the impeller are arranged at intervals, resulting in poor air supply uniformity; for indoor units, the turbofan is composed of a motor, a volute and a fan. Not only the assembly and matching of components is complicated, but also it is easy to cause loud noise, and the air supply mode is similar to that of the impeller, and the air supply is uneven, which makes the heat transfer of each part of the heat exchanger uneven

[0006] It can be seen from the above that in the existing air source heat pump air conditioning system, under a certain motor power, the air supply pressure generated by the impeller or turbofan is low, resulting in a low flow rate of air flowing through the heat exchanger, and the air supply distance Short; and the noise generated by the impeller or turbofan is also relatively large, it is difficult to achieve a good balance between the air supply capacity of the air supply equipment, motor power and noise, if the air supply capacity and heat exchange need to be guaranteed, only by increasing the motor speed , not only the power consumption of the motor increases, which makes the energy utilization rate of the system lower, but also greatly increases the noise generated, which affects the comfort of the user
