Embodiment Construction
[0015] The specific implementation manner of the present invention will be described in detail below in combination with the technical scheme and accompanying drawings.
[0016] How it works in summer cooling conditions:
[0017] In part A of the refrigerant circulation circuit, the first electromagnetic valve 21, the sixth electromagnetic valve 26, and the seventh electromagnetic valve 27 are opened, and the four-way electromagnetic reversing valve 14 is not energized, so that the a terminal of the four-way electromagnetic reversing valve 14 is connected to d end is connected, end b and end c are connected, and end b and end c of the first electromagnetic three-way valve 20 are connected. The high-temperature and high-pressure gaseous refrigerant working medium discharged from compressors 1 and 2 flows into the outdoor heat exchanger 5 through the four-way electromagnetic reversing valve 14 and the first electromagnetic valve 21, and is cooled by outdoor air heat exchange to ...

The invention discloses an air-source heat pump device integrating cool and warm air conditioning and water heating in the cold area, which belongs to the technical field of refrigeration air conditioner. The device consists of two high and low pressure compressors, a flash evaporator, a defrosting coil pipe, a flash gas superheated coil pipe, a compressor heat recovery coil pipe, a low pressure gas supply pressure pipeline and other parts which are connected through pipelines. The device is characterized in that the two high and low pressure compressors in the system have three modes of separate operation, parallel operation, and two-stage compression combined operation; and the two compressors are matched with a four-way electromagnetic directional valve, a three-way electromagnetic valve and an electromagnetic valve to form a refrigeration mode, a heating mode, a hygienic hot water mode and a refrigeration and hygienic hot water combined operation mold. The air-source heat pump device has the advantages that the device not only can refrigerate and produce hygienic hot water while refrigerating in summer; and under the microthermal climate in winter, the device can run stably toprovide the heat needed by indoor heating and hygienic hot water, thereby realizing the integrated cool and warm air conditioning and water heating. The device which is used in a house in the cold area has wide popularization and application space and energy-saving significance.
Description
technical field [0001] The invention belongs to the technical field of refrigeration and air-conditioning, and relates to an air source heat pump device integrating heating and cooling baths in cold regions, in particular to a device that utilizes an outdoor air source to operate stably in low-temperature climates and provide the required heat and sanitary hot water indoors. heat pump unit. Background technique [0002] Energy, in today's rapid economic development, has become the focus of global attention. With the gradual deepening of my country's construction of a conservation-oriented society, how to correctly use energy and rationally develop and utilize renewable energy has risen to a strategic height related to the country's survival and development. However, although my country's urban heating is mainly based on centralized pipe network heating, there are still a large number of small electric, coal, oil, gas boilers and other methods for winter heating. There are ...
