Embodiment 1

[0024] Such as figure 1 As shown, the structural diagram of the first embodiment of the multifunctional air source hot water and air conditioning heat pump unit of the present invention includes: a compressor 3 connected in sequence through refrigerant pipelines, a four-way valve 4, an outdoor heat exchanger 5, The first throttling capillary 7, the air conditioner heat exchanger 16, the third valve 14, the second throttling capillary 9, the hot water heat exchanger 10, the first valve 8, the third valve 14, the second throttling capillary 9, A second valve 13 is connected in parallel at both ends of the pipe section of the hot water heat exchanger 10 and the first valve 8, and a fourth valve 15 is connected in parallel at both ends of the pipe section of the third valve 14 and the second throttling capillary tube 9. A fifth valve 6 is connected in parallel at both ends of the throttling capillary 7, a fan 2 is installed on one side of the outdoor heat exchanger, and a hot wate...

Embodiment 2

[0037] Such as figure 2 Shown is a schematic structural view of the second embodiment of the multi-functional air source hot water and air-conditioning heat pump unit of the present invention, which is an improved variant of the first embodiment, wherein the multi-functional air source of the first embodiment The first valve 8 and the second valve 13 in the hot water and air-conditioning heat pump units are replaced by three-way valves 18, and the structure and control of the system can be simplified by reducing the number of valves.

[0038] In the individual cooling and individual heating modes, the o port and the n port of the three-way valve 18 are connected, the o port and the m port are closed, and the operation mode of other components remains unchanged. And under the modes of separately producing domestic hot water, cooling and domestic hot water, heating and domestic hot water, the o port and the m port of the three-way valve 18 are connected, the o port and the n po...

Abstract

The invention discloses a multifunctional air source and air conditioning heat pump unit. A compressor, a four-way valve, an outdoor heat exchanger, a first throttling capillary, an air conditioning heat exchanger, a third valve, a second throttling capillary, a hot water heat exchanger and a first valve are sequentially connected by virtue of a refrigerating fluid pipeline, a second valve is connected with the two ends of a pipe section including the third valve, the second throttling capillary, the hot water heat exchanger and the first valve in parallel, a fourth valve is connected with the two ends of a pipe section including the third valve and the second throttling capillary in parallel, a fifth valve is connected with the two ends of the first throttling capillary in parallel, one side of the outdoor heat exchanger is provided with a fan, and one side of the hot water heat exchanger and one side of the air conditioning heat exchanger are respectively provided with a hot water pump and an air conditioning water pump. By adopting the unit of the invention, low grade heat energy in the air can be utilized all the year around, five operational modes of independent refrigeration, independent heating, independent domestic hot water production, refrigeration and domestic hot water production as well as heating and domestic hot water production are realized, utilization ratio and regulating performance of product are improved, and energy saving and environmental protection are realized.

Description

technical field [0001] The invention relates to the field of vapor compression refrigeration and air conditioning, in particular to a vapor compression heat pump unit which utilizes air energy for refrigeration, heating and domestic hot water supply. Background technique [0002] The air source heat pump uses the vapor compression refrigeration cycle to utilize the low-grade energy in the outdoor atmosphere to provide heat and cold sources for the air-conditioning system. It has been widely used in residential and commercial buildings. The heat pump device can produce cold and hot water as a medium to pass through the air conditioner terminal, or directly deliver cold and hot air to the room to provide the required cold and heat to the room, thereby ensuring the thermal comfort of the room. During the cooling operation in summer, while supplying cooling to the room, a large amount of condensation heat must be discharged into the outdoor atmosphere, resulting in possible ener...
