The passive ultra-low energy consumption green building at the present stage of China combines the characteristics of Germany and American systems, and passive optimization is carried out with priority. For a building with near zero energy consumption, if the tail end of an air conditioning system still adopts air conditioning equipment in a traditional building, the capacity is large and the air conditioning system cannot run efficiently, so that energy is wasted indirectly.
Referring to fig. 1 to 3, an embodiment of the present invention provides an air conditioner end device 10 for temperature and humidity adjustment of a building with ultra-low energy consumption, the air conditioner end device 10 is disposed in an indoor space of the building, the air conditioner end device 10 includes a liquid supply pipe 19, a liquid return pipe 14, and at least one heat exchange pipe disposed between the liquid supply pipe 19 and the liquid return pipe 14 for passing liquid, a temperature difference exists between the liquid and the temperature of the indoor space, and the heat exchange pipe is used for exchanging heat with air in the indoor space by using the temperature difference; when the liquid temperature is lower than the temperature of the indoor space, the heat exchange tube is also used for condensing the water vapor in the indoor space for dehumidification.
Specifically, the air conditioner end device 10 is directly placed in a room, and the heat exchange pipe is processed into a certain shape, so that the heat exchange area is increased, and the occupied space is reduced. After chilled water is introduced into the heat exchange tube in summer or heating water is introduced into the heat exchange tube in winter, a certain temperature difference is formed between the surface temperature of the heat exchange tube and the air temperature of the indoor space, and the temperature difference enables air around the heat exchange tube to generate natural convection, so that the air conditioner terminal device exchanges heat with indoor air. And because the heat exchange tube is directly arranged indoors, the heat exchange tube also has a radiation heat exchange mode. Especially in summer, when the temperature of liquid in the heat exchange tube is lower than the dew point temperature of indoor air, water vapor in the indoor air moves to the surface of the heat exchange tube under the action of partial pressure difference and is finally condensed on the surface of the heat exchange tube. Meanwhile, natural convection is generated due to the temperature difference between the surface of the pipeline and the ambient air. Natural convection accelerates the condensation of the humid air in the heat exchange tubes with the condensation process being accompanied by latent heat exchange, which also increases the cooling capacity of the air conditioning end unit 10.
In the air conditioning end unit 10 of example 1 shown in fig. 2, in the case where the diameter of the heat exchange pipe is 5.7cm and the space between the respective standpipes is 5cm, when the feed liquid temperature is 8 c and the water flow rate l =0.24m3At/h, cooling load q =315W, wet load d =0.242m3The air-conditioning end device with 0.93m (width) and 1.15m (height) can meet the requirement of a room with square meters of 18.

The collecting device 15 avoids that the ground is polluted by the condensed water.
Referring to fig. 3, the heat exchange tube includes a plurality of vertical tubes 11, which are sequentially connected to each other end to end through a transition tube, and a collecting device 15 is disposed between the heat exchange tube and the liquid supply tube 19 and the liquid return tube 14, so that the collecting device 15 collects the condensed water flowing down when the heat exchange tube has a condensing effect in summer.
