Embodiment 1

[0024] see figure 2, in the specific implementation process, it should be noted that when the system operates the refrigeration function, the gaseous refrigerant is discharged through the exhaust pipe of the compressor 1, and flows through the heat recovery device 2, and then enters from the D connection of the four-way reversing valve 3. The four-way reversing valve, and then flows into the air source heat exchanger 4 through the C interface of the four-way reversing valve (it should be noted that the C interface and the E interface of the four-way reversing valve 3 can be used interchangeably according to the designer's habits) After the refrigerant flows out of the air source heat exchanger, it is throttled through the first throttling member 5 and then enters the use-side heat exchanger 6. The liquid refrigerant absorbs the heat of the user's use-end in the use-side heat exchanger and then becomes gaseous refrigeration. The gaseous refrigerant enters the four-way reversin...

Embodiment 2

[0030] see image 3 , the accumulator with expansion liquid storage function is a double-pipe type liquid accumulator with expansion liquid storage function, and the double pipe type liquid accumulator with expansion liquid storage function ( Figure 7 ) On the basis of the single-pipe type liquid accumulator with expansion liquid storage function, the pipe b 8-5 is added, and the two refrigerant pipes are respectively connected with the throttling part interface and the use-side heat exchanger interface image 3 , the other connection methods are the same as those described in claim 1, and the working mode is basically the same as that of the first embodiment, the difference is that when the unit operates the refrigeration function or the refrigeration and hot water function, the first throttling member 5 comes out after throttling. The refrigerant enters the accumulator 8 from one of the refrigerant pipes, and then the refrigerant comes out from the other pipe of the accumul...

Embodiment 3

[0033] See Figure 4 , on the basis of Embodiment 1, a set of throttle components ( Figure 8 ) instead of the first throttling member 5, the working mode is basically the same as that of the first embodiment, and the different parts in the working mode are specifically, when the unit operates the refrigeration function or the refrigeration and hot water function, the air source heat exchanger 4 comes out. The refrigeration is throttled through the first one-way valve 5-3 and the second throttle member 5-1 respectively and then enters the heat exchanger on the use side. After the flow, the pressure in the expansion bladder is higher than the pressure of the liquid refrigerant in the shell 8-1, so the expansion bladder will expand, and part of the liquid refrigerant in the accumulator will be squeezed out of the shell to participate in the refrigeration cycle. , to achieve the purpose of reducing the refrigerant storage amount in the accumulator in the process;

Abstract

The invention discloses a triple-generation heat pump unit with an expansion liquid storage device, which comprises a compressor, a heat recoverer, a four-way reversing valve, an air source heat exchanger, a throttling element, a use side heat exchanger and a gas-liquid separator, an inlet of the heat recoverer is connected to an exhaust port of the compressor, the four-way reversing valve is provided with four interfaces D, C, S and E, and the four-way reversing valve is provided with four interfaces D, C, S and E; an outlet of the heat recoverer communicates with a connector D of the four-way reversing valve, and an inlet of the air source heat exchanger is connected with a connector C (or a connector E) of the four-way reversing valve. The cold, warm and hot water triple co-generation all-in-one machine has the beneficial effects that the cold, warm and hot water triple co-generation all-in-one machine is achieved; the functions of the air source heat pump system are diversified, use convenience, unit reliability and the like are improved, a certain function priority level does not need to be set in advance, use is very convenient, the performance of the unit is improved, and the reliability of the heat pump system is improved when the heat pump system is in different working modes through the expansion air bag.

Description

technical field [0001] The invention relates to the technical field of heat pump units, in particular to a heat pump unit with a heat recovery function or a heat pump unit with a triple supply function. Background technique [0002] Nowadays, heat pump units with heat recovery function or air source heat pump systems with triple supply function mainly have the following problems: [0003] 1. The common air source heat pump unit has poor ability to adjust the refrigerant circulation volume. Common heat pump systems have few functions, usually only cooling and heating functions; [0004] 2. The common heat recovery heat pump system needs to manually set the function priority in advance, which is very inconvenient to use. The common heat recovery heat pump system usually has three functional modes of cooling, heating and heat recovery. There are two four-way reversing valves. The total heat recovery device and the condenser are installed in parallel and connected to the refr...
