The air-conditioning unit has an integrated structure, which shortens the connecting pipeline of the air-conditioning system, reduces system resistance, and reduces energy consumption. There are 3 air valves in the air conditioning unit, and the opening of the 3 air valves can be changed to realize the continuous change of the air sent into the room by the unit from fresh air to full return air. The outdoor fresh air and exhaust air of the unit are collected in one pipe, and its structure is divided into an inner pipe and an outer pipe, and the interior of the inner pipe and the outer pipe are not connected to each other. Therefore, only one opening is opened on the outer wall to solve the air inlet and exhaust pipes connected with the unit.

Description

Integrated energy-saving air conditioning unit

Technical field

The utility model relates to an air conditioner combined with a two-way ventilation full heat recovery device, and the condenser and the evaporator in the air conditioning system are placed together in one unit. The heat generated by the condenser is utilized by the unit. The dirty air that needs to be discharged during ventilation is taken outside.

Background technique

At present, the condensers of air conditioners are all placed outdoors (some are placed indoors to use cooling water to take the generated heat out of the room), which will inevitably lead to the need for connecting pipelines between indoor and outdoor units, and the longer the pipeline of the unit, the higher the energy consumption. And it takes up a lot of space, and it is inconvenient to operate and maintain. At the same time, the traditional air conditioner can only adjust the indoor temperature and humidity, and cannot solve the problem of indoor and outdoor ventilation. People stay in a closed space for a long time, which will reduce the freshness of the air and bring harm to people's life and work.

Contents of the invention

The utility model provides an air conditioner combined with a two-way ventilation full heat recovery device, and the condenser and the evaporator in the air conditioning system are placed in the same integrated air conditioner unit to perform two-way ventilation indoors and outdoors at the same time. , absorb the heat and humidity in the exhausted dirty air on the heat exchange material, and then bring it back to the room through the introduction of outdoor fresh air, so as to achieve the purpose of energy saving. The heat generated by the condenser in the unit is taken out of the room by the air that needs to be discharged after heat exchange through the heat recovery device.

The technical scheme adopted by the utility model to solve the technical problem is: the heat generated by the condenser in the unit is taken out of the room by the air that needs to be discharged after heat exchange through the total heat recovery device, and the waste air is reused to dissipate heat in the condenser .

There are 3 air valves inside the unit. By changing the opening degree of the 3 air valves, the air sent into the room by the unit can be continuously changed from fresh air to full return air. At this time, the amount of indoor exhaust air passing through the condenser will gradually decrease, and the reduced amount will be supplemented by gradually increasing the amount of outdoor fresh air introduced.

The fresh air and exhaust air introduced by the unit are collected in one pipe, and its structure is divided into an inner pipe and an outer pipe, and the inner and outer pipes are not connected to each other. Therefore, only one opening is opened on the outer wall to solve the air inlet and exhaust pipes connected with the unit, which facilitates the installation.

The beneficial effects of the utility model are: because the air for cooling the condenser utilizes the indoor air that needs to be discharged, the temperature is lower than the (summer) outdoor temperature, the condensation temperature of the refrigerant is reduced, and the energy efficiency ratio of the unit is improved.

The air-conditioning unit has an integrated structure, which shortens the connecting pipeline of the air-conditioning system, reduces the system resistance, and reduces the energy consumption of the unit.

Indoor and outdoor ventilation can be carried out throughout the year. While performing indoor and outdoor two-way ventilation, the heat and humidity in the exhausted air can be recycled to the room, avoiding energy loss.

The air exhausted from the outside is reused for the heat dissipation of the condenser, which reduces the cost of the indispensable ventilator for the existing traditional air-cooled air conditioner.

The unit can be changed into vertical, horizontal, wall-mounted, ceiling-mounted and other forms. The unit can be placed indoors or outdoors, and the installation method is flexible and convenient.

Due to the integrated structure, the unit occupies a small space; it is easy to install, maintain and operate.

Detailed ways

In Figure 1, when the indoor return air valve (4) is completely closed, the indoor return air flow (6) passes through the return air outlet (5), and the total heat recovery device (13) attaches the wet heat in the air flow to the heat exchange material , and then through the air conditioner condenser (8), the heat produced by the condenser is taken away, and the exhaust fan (9) is discharged outdoors by the inner pipe of the new/exhaust air composite air duct (10).

When the indoor return air valve (4) is partially opened, a part of the indoor return air flow (6) is diverted (the split flow is related to the opening degree of the air valve) through the indoor return air valve (4) and through the total heat recovery device (13 ) After the fresh air after the energy exchange is merged, it is sent into the room by the air inlet air valve (14), the blower (1), the air conditioner evaporator, and the air supply port (3).

When the fresh air bypass valve (7) is completely closed, the outdoor fresh air flow (12) is introduced through the lower tuyere of the outer pipe of the new/exhaust air composite air duct (10), and after energy exchange with the total heat recovery device (13), Introduced into the air inlet air valve (14), blower fan (1), and air-conditioning evaporator (2), the cool and fresh air is sent into the room by the air supply port (3).

When the fresh air bypass valve (7) is partially opened, a part of the outdoor fresh air flow (12) diverts (the split flow rate is related to the valve opening degree) and enters the fresh air bypass valve (7), and passes through the total heat recovery device (13) After the energy exchange, the indoor return air flow (6) converges, and the mixed air flow passes through the air conditioner condenser (8), takes away the heat generated by the condenser, and passes through the exhaust fan (9) through the new/exhaust composite air duct (10 ) of the inner tube is discharged to the outside.

The indoor return air valve (4), fresh air bypass valve (7), and air inlet air valve (14) in Figure 1 can automatically adjust the opening degree of each according to the indoor temperature and humidity, so that the unit can always operate under different working conditions. Running at its best.

When the room needs to cool down quickly, the three air valves can be artificially set to fully open. At this time, most of the indoor return air flow (6) will flow through the indoor return air valve (4) and the air inlet air valve (14). , air blower (1), air-conditioning evaporator (2), are sent into the room through the air supply port (3). And from the outdoor fresh air flow (12), most of it will flow through the fresh air bypass valve (7), the air conditioner condenser (8), and the exhaust fan (9) will pass through the inner pipe of the new/exhaust air composite air duct (10) Exhaust outside.

When the above three air valves are fully opened, the air conditioner unit is in the full return air operation state at this time, which is equivalent to the existing traditional air conditioner. In Fig. 2, the air conditioner compressor (11) is a power device that provides cold and heat sources for the unit. The air-conditioning compressor (11) can stop running in the transitional season, which helps to save electricity, and now only the exhaust fan (9) runs.

In Fig. 3, it is a new/exhaust air composite air duct (10), which gathers fresh air and exhaust air in a pipeline, and its structure is divided into two parts, an inner pipe and an outer pipe, and the inner and outer pipes are not connected to each other.

Its advantage is that only one opening is opened on the building exterior wall (15), and the inlet and exhaust pipes connected with the unit can be solved, which facilitates installation.
