Technical field
The utility model belongs to technical field of air conditioner refrigeration more particularly to a kind of accurate feed flow formula heat pipe integrated machine air-conditioning system
System.
Background technique
Since density of equipment is big in communication machine room and data center, calorific value is big, room system to the epidemic disaster of environment and
Dust content etc. all there are certain requirements, therefore should set air-conditioning system.In order to guarantee corresponding epidemic disaster condition, steam compression type
Special air conditioning for device room has obtained commonly used.The temperature of the northern area of China winter and transition season most of the time in spring and autumn are lower than
20 degree, therefore heat pipe integrated machine air-conditioning system can be used, the hot-pipe system of low-power consumption is run when outdoor temperature is lower, reduces energy
Consumption.
Since the pressure difference of compressor operating mode and heat pipe operating mode internal system differs more, it is therefore desirable to solve
Accurate feed flow problem.In patent 2016209000393 by using the throttle valve of two different openings and on liquid pump by parallel connection
Port valve achievees the purpose that accurate feed flow.But the method is compared with conventional system increases two valve members, not only increases first device
Part and pipeline cost are also made troubles for installation and pipe design.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned problems of the prior art, and provide a kind of accurate feed flow formula heat
Pipe all-in-one machine air-conditioning system, the all-in-one machine air-conditioning system are realized by using the big expansion valve of variable frequency pump and aperture regulation range
The purpose of accurate feed flow.
The utility model solves technical problem and adopts the following technical scheme that
A kind of accurate feed flow formula heat pipe integrated machine air-conditioning system, including evaporator, condenser, compressor, fluid reservoir, liquid
Pump, throttle valve, check valve one, check valve two and circuit control system；The output end of the evaporator and the input terminal of compressor
It is connected, input terminal is connected with the output end of throttle valve；The check valve two and compressor parallel；The output end of the condenser
It is connected with the input terminal of fluid reservoir, is located in fluid reservoir more than working media liquid level, the output end phase of input terminal and compressor
Even；The output end of the liquid pump is connected with the input terminal of throttle valve, and input terminal is connected with the output end of fluid reservoir, is located at liquid storage
In tank below working media liquid level；The check valve one is in parallel with liquid pump；The circuit control system controls compressor and liquid
The opening and closing of pump, to control the switching of compressor refrigeration mode and power heat pipe refrigeration mode；When system is with compressor
When refrigeration mode works, compressor is opened, check valve one, throttle valve conducting, while liquid pump is closed, and check valve two ends；When being
When system is with the work of heat-pipe refrigerating mode, liquid pump is opened, and throttle valve, check valve two are connected, while compressor is closed, and check valve one is cut
Only, above two refrigeration mode can be switched over according to environment and demand.
Further, the electric expansion valve that the throttle valve selects aperture regulation range big, due in compressor refrigeration work
In operation mode, operating on low voltage medium becomes high-pressure working medium when passing through compressor, and pressure difference present in system is larger, and
In heat-pipe refrigerating operating mode, working media is extracted by liquid pump and completes evaporative condenser circulation, pressure difference present in system compared with
It is small.
Further, the liquid pump is variable frequency pump, and the effect of flow is also controlled while conveying cooling liquid.
Accurate feed flow formula heat pipe integrated machine air-conditioning system that the utility model provides, the current all-in-one machine of very good solution are empty
Feed flow existing for adjusting system is inaccurate and leads to the phenomenon of evaporator output end steam superheating or steam deficiency, effectively increases and changes
The thermal efficiency increases heat exchange amount.This accurate feed flow formula heat pipe integrated machine air-conditioning system, can be used as electronic equipment, power equipment,
The heat dissipation temp-controlling element of computer floor, communications equipment room.
