Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning in a closed environment, more specifically, to an intelligent indoor air management machine. The present invention also relates to a working method of the intelligent indoor air management machine. Background Art

[0002] Traditional air conditioners generally include indoor units and outdoor units, which are connected by pipes. The outdoor unit is equipped with a compressor and a condenser (heat exchanger). The indoor unit is equipped with an indoor heat exchanger (condenser). The refrigerant is compressed into high-temperature and high-pressure gas in the compressor, and then condenses in one of the indoor heat exchanger and the outdoor condenser to release heat. It evaporates and absorbs heat in the other, achieving heating or cooling functions for the indoor environment. Air conditioners currently on the market generally do not have a fresh air function.

[0003] Multi-split air conditioners are a type of central air conditioner that uses an outdoor unit to connect two or more indoor units through pipes. In summer, it works with the indoor unit to cool the room, and in winter, it works with the indoor unit to heat the room. This type of multi-split air conditioner or central air conditioner cannot introduce outdoor fresh air into the room, and does not have a fresh air mode.

[0004] With the rapid development of China's economy and the continuous improvement of people's living standards, people are increasingly pursuing a high-quality living environment. With air conditioners, people can cool down in the summer and enjoy the warmth of spring in the winter. However, it is impossible to have a better air quality and living environment, because the air conditioner needs to close the doors and windows whether it is cooling or heating, so there is no fresh air indoors. If there is no fresh air circulation indoors, there will be a lack of oxygen, people will feel uncomfortable, chest tightness, shortness of breath, and may also induce other diseases. This is the so-called "air conditioning syndrome". If it is a crowded place, such as a school classroom, kindergarten, or conference room, the air pollution caused by lack of oxygen will be more serious. Scientific research shows that 90% of human diseases are caused by lack of oxygen.

[0005] If there is a machine like this, which can cool when the weather is hot and heat when the weather is cold, and a certain proportion of fresh air can continuously enter the room during cooling or heating, and when the air conditioner is not used in spring and autumn, the machine can be used as a fresh air purifier. This will be a household appliance that people have dreamed of. At present, there is no such household appliance product in the market in the true sense.

[0006] In view of this, it is necessary to provide an air conditioner with cooling, heating and fresh air modes to fill the market gap in order to address the problem that existing air conditioners or central air conditioners cannot have cooling, heating and fresh air functions at the same time.

[0052] In order to achieve the second object of the present invention, the technical solution of the present invention is as follows:

[0053] The indoor air intelligent management machine includes five operating modes, namely: heating mode, cooling mode, fresh air mode, heating and fresh air mode, and cooling and fresh air mode;

[0054] Step 1: When starting the heating mode,

[0055] The air conditioner outdoor unit starts and the indoor unit hot and cold fans start at the same time;

[0056] During heating, the refrigerant gas is pressurized by the compressor to become high-temperature and high-pressure gas, and then enters the condenser / radiator of the indoor unit; the refrigerant gas condenses and liquefies in the condenser / radiator, releasing heat to become refrigerant liquid, while heating the indoor air and raising the indoor temperature;

[0057] The refrigerant liquid is decompressed by the throttling device and enters the heat exchanger / evaporator of the outdoor unit. The refrigerant liquid evaporates and absorbs heat to become refrigerant gas. At the same time, it absorbs heat from the outdoor air and becomes low-pressure refrigerant gas. The low-pressure refrigerant gas enters the compressor again to start the next heating cycle.

[0058] The hot air flow formed by the above heating cycle process passes through the indoor unit condenser / radiator to send the hot air from the air outlet into the room, forming a hot air flow channel;

[0059] Step 2: When starting the cooling mode,

[0060] During cooling, the compressor starts, and the refrigerant gas is pressurized by the compressor to become a high-temperature and high-pressure gas; the refrigerant gas enters the condenser of the outdoor unit, condenses and liquefies to release heat, becomes a refrigerant liquid, and releases heat to the atmosphere; the liquid refrigerant is decompressed by the throttling device and enters the evaporator of the indoor unit, evaporates and absorbs heat, becomes a gas refrigerant, and the refrigerant liquid absorbs heat from the indoor air; the refrigerant gas enters the compressor again to start the next refrigeration cycle;

[0061] The cold air flow formed by the above refrigeration cycle process is sent into the room from the air outlet through the indoor unit condenser / radiator to form a cold air flow channel;

[0062] Step 3: When starting the fresh air mode,

[0063] When the fresh air mode is started, the return air mode is started at the same time;

[0064] Fresh air mode: when the fresh air system is working, the fresh air motor starts, generates negative pressure, and inhales fresh air;

[0065] Fresh air enters the fresh air inlet duct through the fresh air inlet, is discharged from the fresh air outlet, enters the fresh air inlet cavity, enters the heat exchanger from the fresh air inlet side, is discharged from the heat exchanger from the fresh air outlet side, enters the fresh air outlet cavity through the fresh air channel, enters from the lower end of the filter cavity, is discharged from the upper end of the filter cavity, is discharged to the air outlet through the fresh air motor, and enters the room, forming a fresh air airflow path;

[0066] The return air mode is: when the return air system is working, the return air motor starts, the return air motor generates negative pressure, and discharges the dirty air in the room to the outside through the return air system;

[0067] Indoor dirty air enters the return air inlet cavity through the return air inlet, enters the heat exchanger from the return air inlet side, and is discharged from the return air outlet side. It passes through the return air channel and enters the return air outlet cavity, and is discharged to the return air outlet through the return air motor and discharged outdoors, forming a return air flow path.

[0068] Step 4: When starting the heating and fresh air mode,

[0069] The heating mode is the same as step 1 above, and the fresh air mode is the same as step 3 above;

[0070] Step 5: When starting the cooling and fresh air modes,

[0071] The cooling mode is the same as step 2 above, and the fresh air mode is the same as step 3 above.

[0072] The indoor units are all indoor air intelligent management units; the outdoor units are all air conditioner outdoor units;

[0073] The air conditioning component is prior art; the heat exchanger is prior art.

[0074] The present invention has the following advantages:

[0075] (1) The present invention is provided with an air conditioning component and a fresh air component, and the air conditioning component and the fresh air component are separated by a first partition; the present invention has cooling, heating and fresh air functions, and has a heating mode, a cooling mode, a fresh air mode, a heating and fresh air mode, and a cooling and fresh air mode; the use efficiency of the air conditioner is improved, space is saved, and costs are saved;

[0076] (2) The present invention is simple to operate, energy-saving and consumption-reducing, and highly efficient and safe. Because a heat exchanger is installed, the heat exchange efficiency is 70%-80%. Therefore, when fresh air is used, the disturbance to the indoor air temperature is very small, and energy is effectively recovered, thereby achieving the purpose of energy saving and consumption reduction.

[0077] (3) The air conditioning assembly of the present invention shares an air outlet with the fresh air assembly, that is, the air outlet is a common air outlet for cooling air, heating air and fresh air, with a reasonable layout, saving space and cost;

It can automatically turn on and off according to indoor environmental indicators such as air cleanliness, carbon dioxide index, temperature and humidity, and automatically adjust the operating speed and air volume; it can also realize App remote control;

[0079] (5) The present invention can operate the airtight indoor air in four modes, namely, heating mode, cooling mode, heating + fresh air mode and cooling + fresh air mode. In cooling or heating, the present invention can operate both fresh air and return air at the same time. In addition, there is another mode, that is, when the air conditioner outdoor unit is not running, the indoor air intelligent management machine can be used to realize the fresh air mode of the indoor environment, providing a continuous supply of highly efficient filtered fresh air for the room. The present invention can also operate the fresh air and return air separately when cooling or heating is not required (for example, most of the time in spring or autumn), which greatly improves the use efficiency of the machine.

[0080] (6) When the outdoor unit of the air conditioner is not in operation, the present invention can realize the fresh air mode of the indoor environment by relying only on the operation of the indoor air intelligent management machine, thereby providing a steady supply of fresh air that has been efficiently filtered indoors. The present invention has multiple functions and can be used for multiple purposes. It is both an air conditioner and a fresh air purifier, and is a true indoor air management machine (i.e., an air conditioning machine). BRIEF DESCRIPTION OF THE DRAWINGS

[0141] Referring to the attached drawings, it can be seen that the working method of the indoor air intelligent management machine is characterized in that it includes the following steps:

[0142] The indoor air intelligent management machine includes five operating modes, namely: heating mode, cooling mode, fresh air mode, heating and fresh air mode, and cooling and fresh air mode;

[0151] The cold air flow formed by the above refrigeration cycle process passes through the indoor unit condenser / radiator 5.1 to send the cold air from the air outlet 4 into the room, forming a cold air flow channel;

[0152] Step 3: When starting the fresh air mode,

[0153] When the fresh air mode is started, the return air mode is started at the same time;

[0157] Indoor dirty air enters the return air inlet cavity 6.22 through the return air inlet 6.21, enters the heat exchanger 6.3 from the return air inlet side 6.32, and is discharged from the heat exchanger 6.3 from the return air outlet side 6.34, passes through the return air channel 6.23, enters the return air outlet cavity 6.24, is discharged to the return air outlet 6.26 through the return air motor 6.25, and is discharged outdoors, forming a return air flow path (such as Figure 1 , Figure 3 shown);

[0159] The heating mode is the same as step 1 above; the fresh air mode is the same as step 3 above;

[0160] Step 5: When starting the cooling and fresh air modes,

[0161] The cooling mode is the same as step 2 above, and the fresh air mode is the same as step 3 above.
