Abstract
The utility model discloses an air-conditioning water system with bypass valves. The air-conditioning water system with bypass valves comprises a double-conversion water pump. The bypass valves are disposed at an inlet and an outlet of the double-conversion water pump. The bypass valves are pressure difference control-regulating valves. The air-conditioning water system with bypass valves has the advantages that variable frequency regulation of the water pump is limited, up to 20-30% of design flow at most, and the opening of the bypass valves can be regulated to supply lower flow for user sides; and when a frequency converter fails, variable flow operation of the user sides can be achieved through the bypass valves.
Description
Technical field
The utility model relates to a kind of system, particularly relates to a kind of air-conditioner water system.
Background technology
Air-conditioner water system secondary pump system can adopt converter technique, reduces energy consumption when underload, during operated by rotary motion secondary pump frequency conversion system, the pressure reduction bypass pipe is set no longer.But the adjustable flow of variable frequency pump is limited, if variable frequency pump is transferred to minimum discharge, can not satisfy the terminal more demand of underload.
The utility model content
Technical problem to be solved in the utility model provides a kind of air-conditioner water system, and it has solved when variable frequency pump is transferred to minimum discharge and frequency converter and is broken down, the demand of air-conditioning system underrun.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of air-conditioner water system with bypath valve, it is characterized in that it is included in double conversion water pump import and export bypath valve is set, and this valve is pressure reduction control and regulation valves.
Positive progressive effect of the present utility model is: the utility model has solved two problems: 1. pump variable frequency is regulated limited, can be transferred at most the 20-30% of design discharge, when the required flow of user's side more hour, can satisfy the more requirement of low discharge by the aperture of regulating by-passing valve; 2. when frequency converter breaks down, can realize the operation of user's side variable-flow by by-passing valve.
Description of drawings
Fig. 1 is the theory diagram of the utility model air-conditioner water system.
The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the utility model comprises with the air-conditioner water system of bypath valve: double conversion water pump 1; At described double conversion water pump 1 import and export bypath valve 2 is set; Described bypath valve 2 is pressure reduction control and regulation valves.
Pressure reduction control and regulation valve plays the effect of bypass in the utility model.Air-conditioner water system preferentially adopts pump variable frequency, and when variable frequency pump was transferred to minimum discharge and frequency converter and is broken down, for satisfying the demand of air-conditioning system underrun, part discharge flow through from the pressure reduction bypass pipe.
The utility model has solved two problems: 1. pump variable frequency is regulated limitedly, can be transferred at most the 20-30% of design discharge, when the required flow of user's side more hour, can satisfy the more requirement of low discharge by the aperture of regulating by-passing valve; 2. when frequency converter breaks down, can realize the operation of user's side variable-flow by by-passing valve.
Above-described embodiment is as to restriction of the present utility model, all any modifications of doing in scope of the present utility model, is equal to replacement, improvement etc., all belongs to protection domain of the present utility model.
