摘要:
The present disclosure discloses a control method for an air conditioning system. The air conditioning system at least includes a compressor, a heat exchanger and a throttle device. The operation phase of the air conditioning system at least includes a start-up phase and a stable phase. The control method includes an action that in the start-up phase, the operating time of the compressor is set as t, when t is greater than 0 and less than 60s, an operating frequency F of the compressor is controlled to be less than 75Hz, and a frequency rise speed per second V f of the compressor is controlled to be less than 1.25Hz/s. The control method for the air conditioning system according to the embodiment of the present disclosure can slow down frosting on the multi-channel heat exchanger during the heating operation of the system, and improve the performance of the system.

A manifold assembly and a heat exchanger are disclosed. The manifold assembly comprises a manifold (100), a distributing device arranged in the manifold (100) and provided with a distributing opening (401), an adjusting member (500) movably arranged on the distributing device and used for adjusting the distributing opening (401), and a driving member (600); the driving member (600) drives the adjusting member (500) to move by magnetic force so as to adjust the distributing opening (401). By changing the position of the driving member, the manifold assembly and the heat exchanger may change the position of the adjusting member through the magnetic force effect, so that the distributing opening is adjusted, and the distribution of coolant is further adjusted, thus satisfying requirements in different operation environments, and improving applicability and distribution effect of the coolant.

A heat exchange device is provided. The heat exchange device comprises: a first heat exchanger (1) defining an upper end and a lower end; a second heat exchanger (2) defining an upper end connected to the upper end of the first heat exchanger (1) and a lower end spaced apart from the lower end of the first heat exchanger (1) in a longitudinal direction, such that a predetermined angle between the first heat exchanger (1) and the second heat exchanger (2) is θ, where 0
摘要:
A micro-channel heat exchanger comprises a first header (1); a second header (2); a plurality of tubes (3); a plurality of fins (4) each disposed between two adjacent a plurality of tubes; a first end cover (8a) formed with a first center hole and fixed to a proximal end of the first header; a first sleeve (10a) mounted to the first end cover (8a); a first distribution-collection tube (5) formed with a plurality of first openings (7a), and fixed to the first sleeve (10a) and extend into the first header (1); and a first fixing nut (11a) screwed onto the first end cover (8a). According to the present invention, the length of the distribution-collection tube (5) extended into the header (1) is adjustable, and the distribution-collection tubes (5) may be detachably assembled to the header (1), so that it is easy to replace and maintain the distribution-collection tube (5), thus enhancing the applicability.

A heat exchanger is provided, comprising: an inlet header (2) defining a refrigerant chamber therein; an outlet header (6) spaced apart from the inlet header (2); a plurality of tubes (3), two ends of each tube (3) being connected and communicated with the inlet and outlet headers (2, 6) respectively; a plurality of fins (7), each of which is interposed between adjacent tubes (3), and a distribution tube (1) disposed outside the refrigerant chamber and formed with a distribution opening, through which the distribution tube is communicated with the refrigerant chamber.
摘要:
The present invention discloses a fin for a heat exchanger, the fin comprises a plurality of fin plates (10) which are adjacent to one another, each of the fin plates (10) is formed with louvers (20); and a connecting portion which connects adjacent fin plates at an end of the adjacent fin plates. The connecting portion comprises a middle curved section (31) and side curved sections (32) located on the sides of the middle curved section (31), and the curvature radius of the middle curved section (31) is larger than the curvature radius of the side curved sections (32). With the technical solution of the invention, since the contact area between the flat tubes and the fin increases, the fin efficiency is increased and thus the heat exchange performance of the heat exchanger is enhanced.
