Description
Technical Field
The invention relates to the technical field of building energy conservation.
Background
The full-scale test in the prior art shows that: when the indoor is in a refrigerating state, the outdoor wall cold load when the indoor and outdoor temperature difference is 10 ℃ and the solar radiation intensity is 175 watt/square meter is 3.2 times of the outdoor wall cold load caused by the independent indoor and outdoor temperature difference of 10 ℃. When the indoor environment is in a heating state, the temperature difference between the indoor environment and the outdoor environment is 18 ℃, the solar radiation intensity is 175W/square meter, the heat load of the outer wall is zero, namely the heat energy generated by the solar radiation just meets the requirement of the outer wall; the single factor of 18 ℃ of indoor and outdoor temperature difference causes the heat load of the outer wall to be 23.2 watts/square meter. The above studies indicate that the temperature rise effect of the solar radiation intensity on the external wall is a significant influence factor of the air conditioning load. If the temperature condition of the outer wall can be utilized comprehensively, the energy consumption of the air conditioning system can be greatly reduced.
With the development of economic society, more and more buildings use air conditioning systems, and the demands of people are more and more diversified. In winter, the temperature of each room in a building with a heating guarantee (such as heating or central air conditioning) is generally high, and even if an air conditioner is not started in one room, the room temperature is not low, because the temperature of a partition wall between the room and an adjacent room is high. Some users in a room may have a need to lower the room temperature by exercising, eating hot pots. Similarly, in summer, there may be some room users who have a need to raise the indoor temperature. When the temperature condition of the outer wall is utilized comprehensively, the temperature regulation requirement of the off-season in each room is considered.
The fluctuation of the heat load or the cold load of the same building under the same meteorological conditions is small, so that the system can be operated more stably if the operation of the heat pump system is controlled according to the compressor power under the historical meteorological conditions.

The invention can utilize the ambient gas to adjust the temperature of the outer wall, thereby reducing the heat load or the cold load of the building and playing a remarkable energy-saving effect. The invention regulates the running power of the compressor in advance according to the historical data matched with the meteorological conditions, greatly prolongs the stabilization period, reduces the fluctuation of the water supply temperature, improves the experience of users in each room of the building, obviously reduces the starting and stopping times of the compressor and prolongs the service life of the compressor.
Because the vertical section of the air pulling cap is in a trapezoid shape with a large top and a small bottom, the top part of the air pulling cap, which is sealed, plays a role in shielding the air pulling hole, and rain and snow or other sundries can not fall into the air pulling cap when falling from top to bottom.
The filter screen can prevent great debris from getting into temperature regulation system. Because the air-extracting inlet is positioned at the bottom of the air-extracting plate, when the corresponding air-extracting electromagnetic valve is closed (or under the action of external wind), sundries such as leaves and the like attached to the filter screen can fall off from the filter screen under the action of self gravity.
The environmental temperature sensor is not arranged at the position exposed to the sun because the temperature of the air near the wall body is higher than the environmental temperature when the sunlight irradiates, so that the temperature sensor cannot detect the real environmental temperature. After the air starts to circulate, the air temperature of the adjacent wall body can be rapidly consistent with the ambient air temperature under the action of the airflow. The environment temperature sensor is arranged on the sun-back surface of the building, so that the real environment temperature can be detected, and a foundation is provided for more accurate adjustment.
In the judgment of the first condition and the second condition, the difference between the target temperature TM and the ambient temperature TH is not considered, and when the temperature of the user needs to be raised, as long as the current ambient temperature is higher than the current indoor temperature, even if the ambient temperature is lower than the target temperature, the room can be raised more quickly by opening the air exhaust solenoid valve. Of course, when the temperature of the room is increased to TS ≧ TH, the air-extracting electromagnetic valve needs to be closed at this time to avoid increasing the heat load of the room. The same reasoning is true when the user needs to cool down.
Because the air-drawing electric control device carries out judgment and adjustment operation once every 5 +/-1 seconds, the air-drawing electromagnetic valve is closed within 5 +/-1 seconds after TS is TH, and the air is continuously drawn when TS is TH without increasing the heat load or the cold load in the room, therefore, the outer wall temperature adjusting method not only effectively utilizes the energy in the environmental gas, but also can avoid increasing the heat load or the cold load in the room in time.
In the judgment of the condition one and the condition two, the difference of winter and summer is not considered any more, as long as the environment temperature TH is favorable for leading the indoor temperature TS to approach to the target set by the user, the corresponding gas extraction electromagnetic valve is opened, the temperature of the outer wall is changed by utilizing the environment gas, and therefore the temperature adjusting system can also play an active role when the user has the demand of out-of-season.
The setting of baffling passageway has prolonged the route of ambient gas when through pulling out the gas board inner chamber, can make ambient gas carry out more abundant heat exchange through pulling out the gas board and the outer wall of building, improves the utilization ratio to the energy (heat energy or cold energy) that contain in the ambient gas.
When the water supply temperature is within 2 ℃ above and below the water supply target temperature TG (the interval of 2 ℃ above and below is 4 ℃), the heat pump electric control device does not change the starting and stopping state of the compressor, so that the starting and stopping times of the compressor are reduced, the system can run more stably, and the service life of the compressor is prolonged.
Historical experience shows that statistically, under the same meteorological conditions, the running power fluctuation of the compressor is small; the heat pump electric control device controls the running state of the compressor according to the average power under the same meteorological conditions in the stable period of the next hour, so that the time of the stable period can be greatly prolonged, the fluctuation of the water supply temperature is reduced, the experience of users in each room of a building is improved, the starting and stopping times of the compressor are greatly reduced, and the service life of the compressor is prolonged. As is known to all, the current of the electric appliance is several times of that of the electric appliance in stable work when the electric appliance is started, the starting and stopping times of the compressor are reduced, the energy consumption is also reduced, and the energy-saving effect is obvious in the long-term operation process.

The humidity sensor 15, the wind speed sensor 14 and the main electromagnetic valve 13 are respectively connected with the gas-drawing electric control device 5;
the filter screen can prevent great debris from getting into temperature regulation system. Because the air extracting inlet 9 is positioned at the bottom of the air extracting plate 2, when the corresponding air extracting electromagnetic valve 12 is closed (or under the action of external wind), sundries such as leaves and the like attached to the filter screen can fall off from the filter screen under the action of self gravity.

The throttling device 27 is embodied as a capillary tube or a throttle valve; the heat pump refrigerating and heating system is a common air source heat pump system, and the specific connection relationship is shown in fig. 5 and is not described again. The fan coil 16 is provided with a fan coil electric control device 17; the compressor 25, the throttling device 27, the two-position four-way electromagnetic valves 26 and the connecting pipeline form the heat pump main machine 22; an indoor temperature sensor 28 is arranged at an air inlet of the fan coil 16, and the indoor temperature sensor 28 is connected with the fan coil electric control device 17; the fan coil 16 is arranged in the room of the building 1 and is arranged corresponding to the room in the building 1 one by one; a water supply temperature sensor 29 is arranged in the water supply main pipe 19, and a return water temperature sensor 30 is arranged in the return water main pipe 20;

The environmental temperature sensor 4 is not disposed at the position exposed to the sun because the temperature of the neighboring wall is higher than the environmental temperature when the sunlight irradiates, so that the temperature sensor cannot detect the real environmental temperature. After the air starts to circulate, the air temperature of the adjacent wall body can be rapidly consistent with the ambient air temperature under the action of the airflow. The ambient temperature sensor 4 is arranged on the back and the sun of the building, so that the real ambient temperature can be detected, and a foundation is provided for more accurate adjustment.
The invention also discloses an operation method of the building energy-saving air-conditioning system, which comprises an outer wall temperature adjusting method and a heat pump system operation method;
in the operation process of the building energy-saving air-conditioning system, a user in each room of the building 1 automatically controls the on-off state of the fan coil 16 in the room through a remote controller and automatically sets the temperature in the room;
the target temperature of the room set by the user is TM, the actual temperature in the room detected by the indoor temperature sensor 28 is TS, the ambient temperature detected by the ambient temperature sensor 4 is TH,
TS, TM and TH are real numbers and the units are all centigrade degrees; when a user in a room turns off the fan coil 16 in that room, both the TM and TS values for that room are empty;
the air-pulling electric control device 5 obtains the indoor temperature TS detected by the indoor temperature sensors 28 in each room through the heat pump electric control device 31 and the fan coil electric control device 17;
the method for adjusting the temperature of the outer wall comprises the following steps: the air drawing electric control device 5 carries out judgment and adjustment operation once for each room adjacent to the outer wall of the building 1 every 5 +/-1 seconds;
judging and adjusting the operation: when the value of TM of a room adjacent to the outer wall of the building 1 meets any one of the following first condition and second condition, the air-extracting electric control device 5 controls the air-extracting electromagnetic valve 12 corresponding to the room to be opened; when the following condition I and the condition II are not met, the gas-drawing electric control device 5 controls the gas-drawing electromagnetic valve 12 corresponding to the room to be closed;
the conditions are as follows: TM and TS are not empty, TM is less than TS, and TS is greater than TH; at the moment, the user needs to reduce the indoor temperature, and when the ambient temperature is lower than the indoor temperature, the electromagnetic valve is opened, so that the temperature of the outer wall of the room can be reduced by utilizing the ambient air temperature, and the cold load of the room is reduced.
The second condition is as follows: TM and TS are not empty, TM is greater than TS, and TS is less than TH; at the moment, the user needs to raise the indoor temperature, and when the ambient temperature is higher than the indoor temperature, the electromagnetic valve is opened, so that the temperature of the outer wall of the room can be raised by utilizing the ambient air temperature, and the heat load of the room is reduced.
In the judgment of the first condition and the second condition, the difference between the target temperature TM and the ambient temperature TH is not considered, and when the user needs to heat up, as long as the current ambient temperature is higher than the current indoor temperature, even if the ambient temperature is lower than the target temperature, the room can be heated up more quickly by opening the air purge solenoid valve 12. Of course, when the temperature of the room is increased to TS ≧ TH, the air-extracting electromagnetic valve 12 needs to be closed at this time to avoid increasing the heat load of the room. The same reasoning is true when the user needs to cool down.
Because the gas-drawing electric control device 5 carries out judgment and adjustment operation once every 5 +/-1 seconds, the gas-drawing electromagnetic valve 12 is closed within 5 +/-1 seconds after TS is TH, and the heat load or the cold load in the room can not be increased by continuing drawing gas when TS is TH, therefore, the method for adjusting the temperature of the outer wall effectively utilizes the energy in the environmental gas, and can avoid increasing the heat load or the cold load in the room in time.
In the judgment of the first condition and the second condition, the difference between winter and summer is not considered any more, as long as the environment temperature TH is favorable for enabling the indoor temperature TS to approach to the target set by the user, the corresponding gas extraction electromagnetic valve 12 is opened, the temperature of the outer wall is changed by utilizing the environment gas, and therefore the temperature adjusting system can also play an active role when the user has the demand of out-of-season.
After the gas-drawing electromagnetic valve 12 is opened, under the gas-drawing action similar to a chimney, the environmental gas at the corresponding room enters the inner cavity of the gas-drawing plate 2 from the gas-drawing inlet 9, then enters the gas-drawing cylinder 6 through the gas-drawing outlet 10, the gas-drawing branch pipe 11 and the gas-drawing main pipe 3, and finally enters the atmosphere through the gas-drawing hole 8 on the gas-drawing cap 7.
The top wall of the inner cavity of the gas-extracting plate 2 is downwards connected with an upper baffle plate 34, the bottom wall of the inner cavity of the gas-extracting plate 2 is upwards connected with a lower baffle plate 35, and the upper baffle plate 34 and the lower baffle plate 35 are alternately distributed and enclose a baffle channel 36; the gas drawing inlet 9 is positioned at one end of the deflection channel 36, and the gas drawing outlet 10 is positioned at the other end of the deflection channel 36;
after entering the gas stripping inlet 9, the ambient gas flows along the deflection channel 36 and flows into the gas stripping manifold 11 through the gas stripping outlet 10.
The baffling channel 36 prolongs the path of the ambient gas when passing through the inner cavity of the gas-extracting plate 2, so that the ambient gas can perform more sufficient heat exchange with the outer wall of the building 1 through the gas-extracting plate 2, and the utilization rate of energy (heat energy or cold energy) contained in the ambient gas is improved.
