Embodiment Construction
[0055] The present invention will be further described below in conjunction with accompanying drawing.
[0056] Such as figure 1 and 2 As shown, an air conditioner and water heater combination system driven by a metering pump includes a six-way valve 1, a two-way metering pump 2, a first one-way valve 3, a second one-way valve 4, a first three-way joint 5, and a second three-way Joint 6 , compressor 7 , first heat exchange device 8 , second heat exchange device 9 and third heat exchange device 10 . The first heat exchange device 8 only has heating capacity, specifically a water heater. The second heat exchange device 9 has cooling and heating capabilities, and is specifically an air conditioner internal unit. The third heat exchange device 10 is an outdoor heat exchange device, specifically an external air conditioner.
[0057] Such as image 3 , 4 As shown in and 5, the six-way valve 1 includes a main valve seat 1-1 and a main valve core. The main valve core is arrange...

The invention discloses an air conditioner water heater combination system driven by a metering pump and a working method thereof. When the air conditioner is cooling, the heat in the high-temperature liquid heat exchange medium generated by the compressor is directly dissipated in the external unit of the air conditioner, resulting in a waste of energy. The present invention is an air conditioner water heater combination system driven by a metering pump, comprising a bidirectional metering pump, a first one-way valve, a second one-way valve, a first three-way joint, a second three-way joint, a compressor, and a first heat exchange load , the second heat exchange load, the third heat exchange load and the six-way valve. The six-way valve includes a main valve seat and a main valve core. The main spool consists of an end piston plate and a flow adjustment plate. The bidirectional metering pump includes a pump casing, a pump liquid plunger, a first variable check valve, a second variable check valve, a third variable check valve and a plunger driving assembly. In the present invention, the two-way metering pump can realize the stepless adjustment of the flow ratio on different heat exchange loads through the cooperation of three variable one-way valves and the pump liquid plunger.
Description
technical field [0001] The invention belongs to the technical field of heat exchange, and in particular relates to an air conditioner and water heater combination system driven by a metering pump and a working method thereof. Background technique [0002] A four-way valve is often used in the heat exchange system of the existing air conditioner unit to switch between the cooling mode and the heating mode. When the air conditioner is cooling, the heat in the high-temperature liquid medium generated by the compressor is directly dissipated in the external unit of the air conditioner, resulting in a waste of energy. At the same time, more and more families are beginning to use air-energy water heaters, which use the high-temperature liquid medium generated by compressors to heat water. Therefore, designing a device that uses the heat wasted in air conditioning units to heat domestic water saves energy. In addition, during the operation of the traditional single plunger meteri...
