1 manifold installation considerations.

In the present system, the main function of the manifold is the diversion of refrigerant. When the branch pipes are installed, the branch pipes are required to be close to the indoor units as much as possible, and the influence of the branch pipes of the indoor units on refrigerant distribution is reduced. During the process of installing the branch pipe, the proper pipe diameter is ensured to be selected. The Y-shaped manifold must be installed so that the manifold is vertical or horizontal, and then the manifold is welded after being fixed, as shown in FIG. 3. The length of the straight pipe section between two adjacent branch pipes is more than or equal to 500mm, the length of the straight pipe section in front of the main pipe port of the branch pipe is more than or equal to 500mm, and the length of the straight pipe section from the branch pipe to the indoor unit part is more than or equal to 500mm, as shown in fig. 4. The Y-shaped branch pipe, whether installed horizontally or vertically, has three fixing points in front and at the back, as shown in FIG. 5:

and a fixed point 1-a position 100mm away from the welding point on the back branch side of the main inlet pipe section.

And the fixed point 2-the position 200mm away from the welding point on the back bifurcation point side of the main branch pipe.

And a fixed point 3-a position 250mm away from the welding point on the branch pipe back bifurcation point side.

The branches of the branch pipe are divided and then run in parallel, and can not be wrapped in an overlapping way. The liquid pipe and the air pipe should have the same pipe length and be laid with the same line. Because the structure of the branch pipe is complex, the heat preservation is ensured to be tight.

1. Common refrigerating and heating functional module

In some embodiments, the indoor unit 61 includes an indoor heat exchanger 611 and an indoor unit pipe 101, and the indoor heat exchanger 611 and the first throttling device 71 are disposed on the indoor unit pipe 101.

After being discharged from the compressor, the high-temperature and high-pressure gas is changed into medium-pressure and low-temperature liquid through the oil separator, the second four-way valve 42 and the outdoor heat exchanger, enters the ordinary indoor unit through the small valve of the liquid side pipe, is throttled, is evaporated and absorbs heat at the indoor side, performs refrigeration of the indoor unit, flows into the vapor-liquid separator through the second large valve 152 and the first four-way valve 41, and returns to the compressor. When the first four-way valve 41 and the second four-way valve 42 are powered and switched, the ordinary internal machine performs internal machine heating.

2. Heat storage defrosting module

In some embodiments, the heat storage module 62 includes a heat accumulator 621 and a heat storage pipeline 102, and the heat accumulator 621 and the second throttling device 72 are disposed on the heat storage pipeline 102.

The heat accumulation defrosting module is only used when the system is in heating operation. When the system is in a refrigerating mode or other modes of operation, the valve of the heat accumulation defrosting module is closed. When the system is in heating operation, the flow direction of a refrigerant in the system is the same as that of a common heating indoor unit, and the heat storage defrosting module is subjected to heat storage without influencing the heating effect of other indoor units by adjusting the opening degree of the electronic expansion valve in the heat storage defrosting module. When the outdoor unit needs defrosting operation, the valve of the common heating indoor unit is closed, the heat storage defrosting module is used for providing heat for defrosting, the defrosting does not take heat from the indoor space, and the indoor comfort is improved.

The heat and frost storage module can be selectively installed. If the master control of the air conditioning system detects that no heat storage defrosting module is connected into the system, executing common indoor defrosting during defrosting; when the heat storage defrosting module is detected to be connected, the system operates according to the set heat storage defrosting control logic, heat storage defrosting is executed during defrosting, and when the heat storage defrosting fails and defrosting cannot be completed, the system performs ordinary internal defrosting operation.

3. Constant temperature dehumidification module

In some embodiments, the thermostatic dehumidifying inner machine 63 comprises a first heat exchanger 631 and a second heat exchanger 632, the first heat exchanger 631 is disposed on a third pipeline 103, one end of the third pipeline 103 is communicated to the second gas-side pipe 32, the other end is communicated to the liquid-side pipe 33, the second heat exchanger 632 is disposed on a fourth pipeline 104, one end of the fourth pipeline 104 is communicated to the first gas-side pipe 31, and the other end is communicated to the liquid-side pipe 33.

After being discharged from the compressor, the high-temperature and high-pressure gas passes through the oil separator and is divided into two paths before entering the four-way valve: the first path passes through the second four-way valve 42 and the outdoor heat exchanger, becomes a low-pressure and medium-pressure liquid, passes through the small valve of the liquid side pipe, enters the constant temperature dehumidification module, is throttled by the third throttling device 73, and then is evaporated and absorbed in the first heat exchanger 631 to refrigerate the first heat exchanger 631. The second path directly enters the constant temperature dehumidification module through the first large valve 151 of the gas side pipe (high pressure), is condensed and releases heat in the second heat exchanger 632, passes through the fourth throttling device 74, is converged with the first path of refrigerant entering the third throttling device 73, and is evaporated and absorbs heat in the first heat exchanger 631.

The two paths are merged into one path, and then flow into the vapor-liquid separator through the second large valve 152 and the first four-way valve 41, and then return to the compressor. Due to the common condensation dehumidification system, the temperature of the air can be reduced simultaneously when dehumidification is carried out. The lower air-out temperature reduces the travelling comfort that the user used. When passing through the constant temperature dehumidification module, the high temperature (medium temperature) and high humidity air is firstly dehumidified and cooled at the first heat exchanger 631, and then is heated at the second heat exchanger 632, so that the outlet air temperature and humidity can be always kept in a comfortable range, and the use experience of a user is improved.

When the constant temperature dehumidification module needs to heat, the first four-way valve 41 and the second four-way valve 42 are powered to change directions, the flow direction of the refrigerant in the first heat exchanger 631 is consistent with that of the ordinary refrigerating and heating indoor unit, the refrigerant condensed and released in the second heat exchanger 632 is converged after being condensed and released in the first heat exchanger 631, and then the refrigerant returns to the outdoor heat exchanger through the liquid side pipe to be evaporated and then returns to the compressor. Compared with the common indoor heating, the constant-temperature dehumidification module has better heating effect because the number of the heat exchangers is two.

When the system detects that the constant temperature dehumidification module is accessed, the air conditioning system main control executes the constant temperature dehumidification function according to the mode requirement set by the user. If the system does not access the module, the system does not have the function, and the user can not set the function. Other functions accessed in the system are not influenced, and the other functions can be normally realized.

In some embodiments, a third throttling device 73 is further disposed on the third pipeline 103, and a fourth throttling device 74 is further disposed on the fourth pipeline 104.

4. Hot water module

In some embodiments, the hot water module 8 comprises a water tank 81 and a fifth pipeline 105, the water tank 81 is disposed on the fifth pipeline 105, one end of the fifth pipeline 105 is communicated to the liquid side pipe 33, the other end of the fifth pipeline 105 is communicated to the first air side pipe 31 through a sixth pipeline 106, and the other end of the fifth pipeline 105 is further communicated to the second air side pipe 32 through a seventh pipeline 107.

The system can provide domestic hot water regardless of any mode. After being discharged from the compressor, the high-temperature and high-pressure gas passes through the oil separator and enters the domestic hot water module from the first large valve 151 of the gas-side pipe (high pressure). Enters the water tank through the electromagnetic valve A to heat the domestic hot water.

(1) The system only needs to produce hot water, and after the refrigerant heats the hot water, the refrigerant passes through a small valve of a liquid side pipe, enters a heat exchanger of an outdoor unit to evaporate and absorb heat, and then returns to the compressor through a four-way valve.
