Detailed Description
The present utility model will be described in further detail with reference to examples, but embodiments of the present utility model are not limited thereto.
Example 1
As shown in fig. 1, the cooling and heating dual-purpose airless air conditioning system mainly comprises three parts, namely an air conditioning unit 1, an air conditioning terminal device 2 and a pipeline switching assembly 3. The air conditioning unit 1 is realized by an air source heat pump unit or a ground source heat pump unit which can output cold water, heat medium water or refrigerant; the air conditioner end device 2 is a terminal device for realizing windless refrigeration or heat dissipation, and can be arranged in any room or place where the air conditioner end device is needed; the pipeline switching component 3 is used for changing the circulation direction of the refrigerant water, the heat medium water or the refrigerant in the air conditioner terminal device 2.
The air-conditioning terminal device 2 is composed of more than one group of terminal heat exchangers 23, that is, if a user only needs to install the terminal equipment in a certain room or place, the number of the terminal heat exchangers 23 in the air-conditioning terminal device 2 is one group or one unit; if the user needs to install the terminal equipment in two rooms or places, the number of terminal heat exchangers 23 in the air conditioning terminal device 2 is two or two, and so on.
The body of each terminal heat exchanger 23 is provided with a water gap communicated with an internal pipeline thereof, wherein the water gap arranged on the side surface of the upper end of the body of the terminal heat exchanger 23 is a water inlet 25, and the water gap arranged on the side surface of the lower end of the body of the terminal heat exchanger 23 is a water outlet 26. The upper water ports 25 of all the terminal heat exchangers 23 are finally required to be combined to form an upper total water port 21 of the air conditioning terminal device 2, and the lower water ports 26 of all the terminal heat exchangers 23 are similarly required to be combined to form a lower total water port 22 of the air conditioning terminal device 2.
Both the water inlet 25 and the water outlet 26 described above can be used for the input and output of hot water, cold water or a refrigerant medium, which is not unidirectional flow. In order to ensure the use effect of the end heat exchanger 23, the water inlet 25 and the water outlet 26 need to be arranged diagonally on the body of the end heat exchanger 23.
The pipe switching assembly 3 is preferably implemented by a manual or electric reversing four-way valve having a, b, c, d four ports. When in connection, the port a and the port b of the reversing four-way valve are connected with the output end of the air conditioning unit 1 through a pipeline, the port c of the reversing four-way valve is communicated with the upper total water gap 21 through a pipeline, and the port d of the reversing four-way valve is communicated with the lower total water gap 22 through a pipeline. The reversing four-way valve is a commonly used product at present, and can change the communication reversing of four ports a, b, c, d in a manual mode or an electric mode, so that the circulating direction of the refrigerant water, the heat medium water or the refrigerant in the reversing four-way valve can be changed.
When the air conditioning unit 1 outputs heat medium water, the heat medium water in the port c of the pipeline switching assembly 3 enters the port d of the pipeline switching assembly 3 after passing through the upper water port 21, the upper water port 25 of the tail end heat exchanger 23, the lower water port 26 of the tail end heat exchanger 23 and the lower water port 22 in sequence as shown in fig. 1, so as to form a heat medium water circulation loop.
When the air conditioning unit 1 outputs the chilled water, the circulating direction of the coal water of the utility model is changed, as shown in fig. 2, that is, the chilled water in the d port of the pipeline switching assembly 3 sequentially passes through the lower total water port 22, the lower water port 26 of the terminal heat exchanger 23, the upper water port 25 of the terminal heat exchanger 23 and the upper total water port 21 and then enters the c port of the pipeline switching assembly 3 to form a chilled water circulating loop.
When the air conditioning unit 1 outputs the refrigerant, the refrigerant in the d port of the pipeline switching assembly 3 sequentially passes through the lower total water port 22, the lower water port 26 of the terminal heat exchanger 23, the upper water port 25 of the terminal heat exchanger 23 and the upper total water port 21 and then enters the c port of the pipeline switching assembly 3 to form a refrigerant circulation loop.
It should be emphasized that the conventional heat exchanger only adopts a unidirectional circulation mode, that is, a mode of up-in and down-out is adopted to circulate the coal water, both hot coal water and cold coal water. Unlike the present utility model, the hot coal water and the cold coal water are respectively circulated in a non-continuous way, namely, the present utility model adopts the way of 'up-in and down-out', namely, after the hot coal water flows out from the upper total water gap 21, the hot coal water firstly enters from the upper water gap 25 of the terminal heat exchanger 23 and then flows out from the lower water gap 26 of the terminal heat exchanger 23; in the present utility model, the cold coal water is "fed in and fed out from the bottom, i.e. after flowing out from the bottom water inlet 22, the cold coal water enters from the bottom water inlet 26 of the end heat exchanger 23 and then flows out from the top water inlet 25 of the end heat exchanger 23.
In order to more clearly illustrate the obvious difference of energy exchange and temperature parameters brought by adopting the mode, the utility model carries out series of experimental comparison aiming at different working conditions, and the following tables are detailed.
Example 2
In this embodiment, a separate drainage system 4 is added to the air conditioner end device 2 based on embodiment 1. The drainage system 4 is used to drain condensed water generated by the end heat exchanger 23 in embodiment 1 to prevent the condensed water from wetting the wall surface or damaging the system structure.
As shown in fig. 3, the drainage system 4 includes a water pump 41, a controller 42, and a drainage unit disposed below each of the end heat exchangers 23. Each drainage unit comprises a water receiving disc 43, a first sensor 44 and a second sensor 45 which are arranged in the water receiving disc 43, a drainage pipeline connected with the water receiving disc 43 and an automatic valve 46 arranged on the drainage pipeline.
The first sensor 44, the second sensor 45, the automatic valve 46 and the water pump 41 are all connected with the controller 42 in a wired or wireless manner, so as to ensure that the controller 42 can open and close the automatic valve 46 and the water pump 41 after receiving the sensing signals of the first sensor 44 and the second sensor 45.
Wherein, the first sensor 44 is used for obtaining a signal that condensed water in the water pan is at a first threshold; when the condensed water in the water receiving tray 43 of any drainage unit reaches a first threshold value, the controller 42 is used for controlling the water pump 41 and the automatic valve 46 of the drainage unit to be opened according to the signal of the first threshold value acquired by the first sensor 44.
The second sensor 45 is configured to acquire a signal that the condensed water in the water pan 43 is at a second threshold value, where the second threshold value should be greater than the first threshold value. When the condensed water in the water receiving disc 43 of any drainage unit reaches the second threshold value, the controller 42 is configured to control the automatic valve 46 of the drainage unit to close the heat exchange water source passage according to the signal of the second threshold value acquired by the second sensor 45.
As described above, the present utility model can be well implemented.
