Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1.
A high-efficiency heat exchanger comprises a body 1 and a reversing device 4.
The body 1 comprises a plurality of groups of heat exchange loops. Each group of heat exchange loops is formed by winding a heat exchange tube 2. The heat exchange tube 2 can be arranged on the radiating fin in a penetrating way, and two ports of the heat exchange tube are positioned on one side of the body 1. Each group of heat exchange loops are arranged in parallel, and the ports of the heat exchange loops are positioned on the same side of the body. Meanwhile, a fan 9 is arranged on one side of the body 1, so that the air circulation speed can be increased, and the wind direction can be kept constant.
The reversing device 4 comprises a plurality of two-position four-way valves 3. And the O end and the P end of each two-position four-way valve 3 are respectively connected with two ends of one group of heat exchange loops. The A end and the B end of the two-position four-way valve 3 are respectively connected with a liquid pipe 6 and an air pipe 7 of the air conditioner.
The number of the heat exchange tube loops is the same as that of the two-position four-way valves, so that each group of heat exchange loops is correspondingly connected with one two-position four-way valve.
Further, the device also comprises a gas collecting pipe 8 and a liquid distributor 5. The gas collecting pipe 8 is connected between the B end of each two-position four-way valve 3 and the gas pipe 7, and can collect or distribute the gaseous refrigerant. The liquid separator 5 is connected between the end A of each two-position four-way valve 3 and the liquid pipe 6, and can distribute or collect liquid refrigerants according to the requirements of different groups of heat exchange loops in the body.
The two-position four-way valve can be a product with the model number of V840-4/2OC-DA06-024 AC-03.
The utility model discloses a working process does:
when the air conditioner performs cooling operation, as shown in fig. 2, the gaseous refrigerant from the air pipe is distributed by the gas collecting pipe, enters the a end of each two-position four-way valve, flows out from the O end of each two-position four-way valve, and enters the heat exchange loop for heat exchange. Then enters from the P end of the two-position four-way valve, flows out from the B end of the two-position four-way valve, passes through the liquid separator and flows into the liquid pipe to realize circulation.
When the air conditioner is in heating operation, as shown in fig. 3, the liquid refrigerant from the liquid pipe is distributed by the liquid distributor, enters the B end of the two-position four-way valve, and then flows out from the O end of the two-position four-way valve to enter the heat exchange loop for heat exchange. Then, the gas flows in from the P end of the two-position four-way valve, flows out from the A end of the two-position four-way valve, is collected by a gas collecting pipe and then flows into a gas pipe, and circulation is realized.
To sum up, be equipped with the utility model discloses an air conditioner, the operating condition of two-position cross valve of accessible control guarantees no matter be refrigeration operation or heating operation, and the flow direction of refrigerant always can be contrary with the air direction, makes the air conditioner be in best efficiency running state.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
