Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
According to hydrodynamics, when the air duct is blocked, the air flow in the air duct flows along the flow path with small resistance. Accordingly, the present application provides an air conditioning system as shown in fig. 3, comprising: an air conditioning system comprising: the air conditioner comprises a shell 1, wherein an air flow channel 11 is formed in the shell 1; along the airflow direction in the airflow channel 11, a first heat exchanger group 2 and a second heat exchanger group 3 are arranged in the airflow channel 11; the first heat exchanger group 2 comprises at least two heat exchangers; the second heat exchanger group 3 comprises at least two heat exchangers; part of the heat exchangers in the first heat exchanger group 2 are communicated with part of the heat exchangers in the second heat exchanger group 3 to form a heat exchange flow path; the air conditioning system comprises at least two heat exchange flow paths, and each heat exchange flow path can exchange heat for all air flows in the air flow channel 11. That is, the projection of the heat exchanger corresponding to each heat exchange flow path on the cross section of the air flow path 11 coincides with the cross section of the air flow path 11, and when one heat exchange flow path works, no matter the air flow in the air flow path 11 passes through the first heat exchanger set 2 and the second heat exchanger set 3 from any position, the heat exchange is inevitably carried out through at least one heat exchanger in a working state, so that the heat exchange efficiency of the air conditioning system is ensured. When one heat exchange flow path works, the condensate water generated on the heat exchanger included in the heat exchange flow path forms a wind resistance, and the heat exchanger on the heat exchange flow path which does not work does not have the condensate water and can not generate the wind resistance, so that the wind resistance received by the airflow in the airflow channel 11 is basically the same, the airflow is forced to flow through the heat exchanger in a working state, the heat exchange effect is ensured, when at least two heat exchange flow paths work simultaneously, the airflow can uniformly pass through all the working heat exchangers, the heat exchange efficiency of each heat exchange flow path is ensured, and the heat exchange performance of the air-conditioning system is integrally improved.
Wherein, an air inlet 12 is arranged on the air flow channel 11, and air flows into the air flow channel 11 from the air inlet 12.
Each heat exchange flow path forms a heat exchange surface having the same cross section as the airflow passage 11. That is, the gas flowing through the gas flow path 11 inevitably exchanges heat when passing through the heat exchange flow path.
The first heat exchanger group 2 comprises at least two first heat exchangers, and all the first heat exchangers are arranged in parallel along the direction perpendicular to the airflow direction in the airflow channel 11. I.e. the projections of all heat exchangers in the first heat exchanger group 2 onto the cross section of the air flow channel 11 coincide with the cross section of the air flow channel 11. It is ensured that the air flow in the air flow channel 11 must flow through the heat exchangers of the first heat exchanger group 2.
The second heat exchanger group 3 comprises at least two second heat exchangers, and all the second heat exchangers are arranged in parallel along the direction perpendicular to the airflow direction in the airflow channel 11. I.e. the projections of all heat exchangers in the second heat exchanger group 3 onto the cross section of the air flow channel 11 coincide with the cross section of the air flow channel 11. It is ensured that the air flow in the air flow channel 11 must flow through the heat exchangers of the second heat exchanger group 3.
The number of the second heat exchanger groups 3 is at least two, and all the second heat exchanger groups 3 are arranged in parallel along the airflow direction in the airflow channel 11. Because the refrigerant can flow through the plurality of heat exchangers, along the flow path of the refrigerant, the heat exchange amount of the heat exchanger at the front is relatively high, and the heat exchange amount of the heat exchanger at the rear is relatively low, in order to ensure the heat exchange uniformity degree of the airflow in the airflow channel 11, the sum of the heat exchange amounts of the plurality of heat exchangers through which the airflow flows is basically the same, and finally, the temperature of each part of the airflow is basically the same, thereby achieving the purpose of uniform heat exchange.
In the first heat exchanger group 2, a sealing structure is arranged between two adjacent heat exchangers; and/or a sealing structure is arranged between the heat exchanger and the airflow channel 11. All the gas in the gas flow channel 11 is forced to flow only through the first heat exchanger group 2.
In the second heat exchanger group 3, a sealing structure is arranged between two adjacent heat exchangers; and/or a sealing structure is arranged between the heat exchanger and the airflow channel 11. All the gas in the gas flow channel 11 is forced to flow only through the second heat exchanger group 3.
The heat exchange flow path comprises a first heat exchange flow path and a second heat exchange flow path, the first heat exchanger group 2 comprises a first heat exchanger 21 and a fourth heat exchanger 32, the second heat exchanger group 3 comprises a second heat exchanger 22 and a third heat exchanger 31, the first heat exchanger 21 and the second heat exchanger 22 are communicated to form the first heat exchange flow path, the third heat exchanger 31 and the fourth heat exchanger 32 form the second heat exchange flow path, part of the air flow in the air flow channel 11 sequentially passes through the first heat exchanger 21 and the third heat exchanger 31, and the rest of the air flow in the air flow channel 11 sequentially passes through the fourth heat exchanger 32 and the second heat exchanger 22. That is, the first heat exchanger 21, the second heat exchanger 22, the third heat exchanger 31 and the fourth heat exchanger 32 are diagonally distributed, and four heat exchangers are diagonally distributed, so that when one heat exchange flow path works, the wind resistance is formed by using the condensed water generated on the corresponding heat exchanger, and the heat exchange flow path which does not work has no condensed water and cannot generate the wind resistance, so that two airflow flow paths with the same wind resistance are generated in the air duct, the airflow is forced to be divided into two parts and flows through the corresponding heat exchangers, and the heat exchange effect is ensured.
Optionally, the first heat exchanger 21, the second heat exchanger 22, the third heat exchanger 31 and the fourth heat exchanger 32 are evaporators; or the first heat exchanger 21, the second heat exchanger 22, the third heat exchanger 31, and the fourth heat exchanger 32 are condensers.
In the first heat exchange flow path, the refrigerant flows through the second heat exchanger 22 and the first heat exchanger 21 in this order; and/or, in the second heat exchange flow path, the refrigerant flows through the third heat exchanger 31 and the fourth heat exchanger 32 in sequence. That is, the flowing direction of the refrigerant is opposite to the flowing direction of the air flow, so that the heat exchange efficiency is further increased.
The air conditioning system has a first state in which one heat exchange flow path operates alone, and a second state in which at least two heat exchange flow paths operate simultaneously.
An air conditioner comprises the air conditioning system.
A mobile tool comprises the air conditioning system or the air conditioner.
