Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
Referring to fig. 1, the present embodiment adopts the following technical scheme: the utility model provides a self-adaptation ambient temperature water system air conditioner, including water system air conditioner host computer assembly 1, circulating water pump 2, comfortable environment space 3, terminal fan coil 4, system control cabinet 5, ambient temperature monitor 6 and constant pressure moisturizing device 7, circulating water pump 2 links to each other with water system air conditioner host computer assembly 1, circulating water pump 2 still links to each other with a plurality of terminal fan coil 4 in the comfortable environment space 3 through the pipeline, system control cabinet 5 links to each other with ambient temperature monitor 6, water system air conditioner host computer assembly 1, circulating water pump 2 through the data line, constant pressure moisturizing device 7 links to each other with water system air conditioner host computer assembly 1 through circulating water pump 2.
It should be noted that the water system air conditioner main unit assembly 1 is a process equipment or system assembly for cooling, heating, cooling water, evaporating water or any other compressor.
It is noted that the water system air conditioner main unit assembly 1 adopts a large-span variable-working-condition design.
In addition, the circulating water pump 2 is a cooling and heating medium circulating water pump.
In the specific embodiment, the refrigerant circulating water pump 2 inputs the refrigerant water into the water system air conditioner host assembly 1 to perform a refrigerating or heating process, and then the refrigerant water is output to the plurality of tail end fan coils 4 arranged in the comfortable environment space 3 through the pipeline, so that the heat exchange of the comfortable environment space 3 is realized, and then the cold (hot) medium water flows back into the cold (hot) medium water pump 2, so that the aim of controlling the internal temperature of the comfortable environment space 3 is continuously circulated. The system control cabinet 5 collects data monitored by the environmental temperature monitor 6 through a data line, and adaptively controls the working temperature and state of the water system air conditioner host assembly 1, and simultaneously controls the start and stop and abnormal protection of the refrigeration (heating) medium circulating water pump 2. The constant-pressure water supplementing device 7 carries out constant-pressure water supplementing on the water system air conditioner.
The working principle of the specific embodiment is as follows: based on the working principle of adapting to the change of the ambient temperature, a set of brand new water system air conditioner design, manufacturing standard and control logic is created. The design and manufacturing standard of the traditional water air conditioner is changed, wherein the temperature of water entering and exiting at the temperature of 35 ℃ is 7 ℃/12 ℃ and the temperature of water entering and exiting at the temperature of 7 ℃ is 40 ℃/45 ℃. When designing and manufacturing the water system air conditioner host, taking the actual demand working condition which accords with the change of the environmental temperature interval as a standard; the design conforming to the large-span variable working condition is adopted, so that the configuration and technological parameters of all components and matched equipment are required to meet the running of the interval variable working condition; and a system which is automatically adapted to the ambient temperature is added to timely change and control the outlet water temperature of the air conditioner host.
When the ambient temperature of the air conditioner host is reduced in the refrigerating mode, the condensing temperature of the air conditioner host is reduced, so that the refrigerating effect is promoted. After the environmental temperature of the other side is reduced, the control temperature of the tail end is still unchanged, the required cooling capacity is reduced, and the heat exchange area of the fan coil of the tail end is also a fixed value and cannot be changed; the temperature difference between the chilled water input into the tail end fan coil and the comfortable space environment can be reduced when the required cooling capacity is reduced under the condition that the chilled water flow and the heat exchange area of the tail end fan coil are unchanged; therefore, the evaporation temperature of the air conditioner refrigerating host can be further increased by increasing the chilled water supply temperature, and finally the efficiency of the air conditioner host is improved.
The heating mode of the air conditioner main refrigerating machine is the reverse working principle of the refrigerating mode, the water supply temperature can be correspondingly reduced after the ambient temperature is increased, and the main heating effect of the air conditioner is correspondingly improved under the condition that the water supply quantity, the comfortable space temperature and the tail end heat exchange area are kept unchanged. Therefore, the energy-saving purpose can be realized by only enabling the air conditioner refrigerating host to adaptively and automatically adjust the water inlet and outlet temperature of the air conditioner refrigerating host according to the change of the ambient temperature. In order to achieve better energy-saving effect, the configuration standard of the air conditioner host equipment is correspondingly improved, so that the air conditioner host equipment can meet the optimal working conditions under different working conditions.
When the self-adaptive environment temperature water system air conditioner works, the tail end coil fan is only required to be ensured to be driven and controlled by the change of the environment temperature under the condition of approximately the same starting time, and the water outlet temperature of the air conditioner main machine is automatically adjusted. And when the ambient temperature is more than or equal to 35 ℃, the standard 7 ℃ water outlet refrigeration working condition is executed, and when the ambient temperature is reduced, the temperature of the chilled water outlet of the modulated cold host machine is correspondingly increased. And similarly, when the heating working condition is executed, the standard 45 ℃ water outlet heating working condition is executed when the ambient temperature is less than or equal to 7 ℃, and when the ambient temperature is increased, the air conditioner host heat medium water outlet temperature is correspondingly reduced. The manufacturing standard of the air conditioner main unit is improved to enable the air conditioner main unit to reach the optimal working state of different working conditions; and then, the environmental temperature data collected by the environmental temperature detector in time is added to drive and adjust the working water outlet temperature of the air conditioner host, so that the energy efficiency of the air conditioner is improved. Because the power of the tail end fan is smaller, the energy consumption of the air conditioner host is large, the energy saving generated by the working condition change of the air conditioner host is far greater than the energy consumption increased by the extension of the running time of the tail end coil fan, and the start and stop times of the tail end fan are correspondingly reduced, so that a better energy saving effect can be generated.
The specific embodiment is applicable to all compressor refrigeration system air conditioners, and the air conditioner host can be a wind source, a water ground source, water cooling, evaporative cooling or any other compressor refrigeration and heating process, and the technical protection scope is considered as long as the system principle is executed.
