Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art without creative efforts based on the technical solutions of the present invention belong to the protection scope of the present invention.
Examples
Referring to fig. 1, the radiation refrigeration method of the air conditioning unit with multiple air conditioning units in space, fluorine and ground water provided by this embodiment is as follows: the method comprises the steps that a user inputs a target indoor temperature Ts, an air conditioning unit detects an actual indoor temperature Ta and an actual relative humidity RH, whether the actual indoor temperature Ta is greater than the target indoor temperature Ts is judged, if the actual indoor temperature is not greater than the target indoor temperature, a radiation refrigeration mode is not started, if the actual indoor temperature is greater than the target indoor temperature, whether the actual relative humidity RH is smaller than a set relative humidity RHs is continuously judged, if the actual relative humidity RH is smaller than the set relative humidity RHs, the air conditioner starts the radiation refrigeration mode, if the actual relative humidity RH is not smaller than the set relative humidity RHs, the air conditioner can simultaneously start a dehumidification mode, at the moment, the air conditioner continuously detects the actual relative humidity RH, and judges whether RH is smaller than RHs-b or not, b is a humidity interval value, the value range of b is 0-10%, the preferential 5%, the air conditioner closes the dehumidification mode if yes, and if not, the dehumidification is continuously carried out. The radiation refrigeration mode refers to that a water module of the Tianfu-Geohui multi-connected air conditioning unit exchanges heat with an outdoor unit, and circulating water in the water module is cooled and introduced into a user floor heating. And the dehumidification is completed by an indoor unit of a natural fluorine ground water multi-connected air conditioning unit.
The refrigeration mode of the natural fluorine ground water multi-connected air conditioning unit in the embodiment is changed from the traditional heat exchange between an indoor unit and an outdoor unit to indoor cold air blowing, to the mode that a water module refrigerates cold water and feeds the cold water to indoor ground heating, and the cold water radiates from the ground heating to the ground and radiates from the ground to the indoor for refrigeration. The traditional water module refrigeration technology is used for supplying cold water to the fan coil, and the indoor air is blown to circulate through the fan coil to cool. In addition, ground radiation refrigeration is also different from other ground radiation refrigeration for dehumidifying by using a fan coil, but an air conditioner indoor unit in the system is used for dehumidifying, and the air conditioner indoor unit has lower heat exchange temperature and better and faster dehumidifying effect than the fan coil indoor unit. The method of the embodiment combines the advantages of energy conservation and comfort of ground radiation refrigeration and quick dehumidification of the indoor unit of the air conditioner, so that the refrigeration of a user is more comfortable, quieter and more energy-saving in summer.
After the air conditioning unit opens the radiation refrigeration mode, let in cold water in the user's ground warms up, in order to prevent that indoor ground temperature from crossing the condensation that appears excessively, the method still includes anti-condensation control mode:
an indoor line controller of the air conditioning unit detects an actual indoor temperature Ta and an actual ground temperature Tf, calculates a dew point temperature Td under the current condition,
and judging whether Ta is greater than Ts-1, if yes, further judging whether Tf is less than Td + a, a is a temperature range value, the value range of a is 0-5 ℃, preferably 1 ℃, if yes, closing the radiation refrigeration mode, further judging whether Tf is greater than Td + a, preferably 1 ℃, and if yes, exiting the anti-condensation control mode.
After the air conditioning unit starts the radiation refrigeration mode, the actual relative humidity RH in the room needs to be detected in real time to ensure that the humidity in the room is proper, and therefore, the continuous dehumidification mode is needed:
an indoor line controller of the air conditioning unit detects actual relative humidity RH,
judging whether Ta is greater than Ts-1, if yes, further judging whether RH is greater than RHS, wherein RHS refers to set relative humidity, and if yes, starting a dehumidification mode; and the dehumidification is completed by an indoor unit of a natural fluorine ground water multi-connected air conditioning unit. And further judging whether RH is less than RHS-b, b is a humidity interval value, the value range of b is 0-10%, preferably 5%, and if yes, exiting the dehumidification mode. After the radiation refrigeration mode is started, the actual relative humidity is detected in real time, the humidity in the room is controlled to be in a proper range, and the effect of further preventing the ground from dewing is achieved. Because the dew point temperature is increased if the indoor humidity is increased, and the ground temperature is relatively low, the condition that the ground temperature is lower than the dew point temperature to cause condensation is easy to occur, so that the humidity control also plays a certain role in preventing the ground from condensation.
The method of the embodiment solves the problems of discomfort in refrigeration and noise of the traditional Tianfu and Geohu multi-connected air conditioning unit, further realizes intelligent control of indoor humidity of a user, prevents dew condensation on the ground, and ensures comfort of the user and no influence on the quality of the floor.

The system structures of the outdoor unit 1, the water module 2 and the indoor unit 3 in this embodiment are the same as those of the traditional air conditioning unit with multiple air conditioners and are not described again. The indoor unit 3 and the water module 2 are connected with a refrigerant pipeline of the outdoor unit 1, heating and refrigerating are carried out through heat and cold generated by the refrigerant pipeline, the water module 2 converts the heat and the cold of the refrigerant pipeline into hot water and cold water through a water side heat exchanger of the water module, and the hot water and the cold water are distributed to the floor heating 5 of each room through the water pump 9 and the water collector 11 and are used for heating and radiation refrigerating of the floor heating 5.
