Background
The water-cooling water chilling unit in the prior art comprises a water source heat pump unit with a water channel switched, and a single drying filter structure is mostly adopted, namely one compressor corresponds to one drying filter. Because the filtering flow that a single drier-filter can provide is slightly small, when a large-flow filtering task needs to be dealt with, the filtering speed is slow sometimes, which affects the normal use of the evaporation plate heat exchanger, and although the large-capacity drier-filter can meet the requirement, the selectable specification of the large-capacity drier-filter is few and the price is high. For various reasons, such as supply, some models of compressors may not find a suitable desiccant filter to meet the liquid supply requirements of the evaporator.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
An air conditioning system with double parallel drying filters comprises a compressor 1, wherein an outlet of the compressor 1 is connected with an inlet of a condensing plate type heat exchanger 2, an outlet of the condensing plate type heat exchanger 2 is connected with inlets of two parallel drying filters 3, outlets of the two drying filters 3 are connected with an inlet of a thermal expansion valve 4, an outlet of the thermal expansion valve 4 is connected with an inlet of an evaporating plate type heat exchanger 5, and an outlet of the evaporating plate type heat exchanger 5 is connected with the other end of the compressor 1.
In the present embodiment, the bulb 41 of the thermostatic expansion valve 4 is attached to the outlet pipe of the evaporation plate heat exchanger 5.
In this embodiment, the balance pipe of the thermostatic expansion valve 4 is connected to the outlet of the evaporating plate heat exchanger 5.
In the present embodiment, a gas-liquid separator 6 is provided in a pipe connecting the evaporation plate heat exchanger 5 and the compressor 1.
The working process and the principle thereof are as follows:
the compressor 1 compresses the gaseous refrigerant into high-temperature high-pressure gaseous refrigerant, the gaseous refrigerant is sent to the condensing plate heat exchanger 2 for cooling, the liquid refrigerant which is changed into medium-temperature high-pressure liquid refrigerant after being cooled enters the two drying filters 3 for filtering and dehumidifying, compared with the conventional single drying filter 3, the two drying filters 3 work simultaneously, the large-capacity filtering and dehumidifying requirement can be met, compared with the directly selected large-capacity drying filter 3 with less specification types, the liquid refrigerant can be matched with the drying filter 3 suitable for the corresponding compressor 1 more accurately, the medium-temperature liquid refrigerant is changed into low-temperature low-pressure vaporous gas-liquid mixture through the throttling and pressure reducing effect of the thermostatic expansion valve 4, the opening degree of the thermostatic expansion valve 4 is controlled through the temperature sensing bag 41, at the moment, the liquid in the mixture is more, and is vaporized through the effect of the evaporating plate heat exchanger 5, most of the mixed condensing agent is changed into gas, the gas-liquid separator 6 separates the liquid and gas condensing agents, the gas condensing agent steam rises, the liquid condensing agent sinks to the bottom of the gas-liquid separator 6, gradually vaporizes and rises, and finally the gas condensing agent returns to the compressor 1 to continue to compress and continue to circulate for refrigeration. The use of the gas-liquid separator 6 prevents the compressor 1 from being damaged by large amounts of liquid refrigerant drawn into the inlet of the compressor 1.
Based on the above: the double drying filters are connected into the system in parallel, so that the adjusting capacity of drying and filtering is increased, and a large-capacity unit is convenient to match with the drying filters; the cost is reduced, the adjustable range of the drying filters is increased, the two drying filters are connected in parallel to have a wider adjustable range, and the reliable operation of the unit can be better protected.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
