Description
Technical field
A kind of freezing unit control system is the utility model is related to, is used to freeze cooling system in unit more particularly, to one kind
The energy-saving control system of system.
Background technology
Chilled water production system is general mainly (empty by water chilling unit host, cooling water pump, blower fan of cooling tower, end-equipment
Adjust case) or fan coil composition.Other accessory systems include：Cooling water, the water replanishing device of chilled water, agent adding device for treatment of water
Deng.
The cooling system of refrigerator mainly includes cooling tower and cooling pump, and cooling tower is the contact using water and air, is led to
Pervaporation effect freezes a kind of equipment of unit caused heat in process of refrigerastion to disperse.Freeze the mistake in refrigeration of unit
Cheng Zhong, refrigerant become gaseous state by liquid, in order that refrigeration unit possesses refrigeration again, it is necessary to it is become again by gaseous state
Liquid, cooling water is thus needed to be cooled down, cooled to it.It can be seen that the effect of cooling tower is to make refrigerant in gaseous state and liquid
Toward complex transformation between state, so that refrigerator reaches the purpose of refrigeration.
Cooling pump and blower fan are that whole day 24h is constantly in running status at present, in the case of compressor emergency shutdown is freezed still
Running, it is impossible to it is out of service in time, thus cause unnecessary waste.
Utility model content
The purpose of this utility model is exactly a kind of for freezing in order to be provided the defects of overcoming above-mentioned prior art to exist
The energy-saving control system of cooling system in unit.
The purpose of this utility model can be achieved through the following technical solutions：
It is a kind of to be used to freezing the energy-saving control system of cooling system in unit, including host computer and all connect the host computer
Freezing machine host, cooling water pump and cooling tower, it is described freezing machine host coolant outlet pass through cooling water pump connection cooling
The entrance of tower, the cooling water inlet of the outlet connection freezing machine host of the cooling tower；The freezing machine host includes connecting successively
Evaporator, compressor and the condenser connect, the coolant outlet and cooling water inlet are located on condenser.
The condenser is connected with evaporator by the pipeline provided with choke valve.
The chilled water outlet and entrance of the evaporator connect the corresponding chilled water gateway of air-conditioning box respectively.
The chilled water outlet of the evaporator is connected by the chilled water inlet of chilled water pump and air-conditioning box.
The freezing machine host connects host computer by RS485 interfaces.
The host computer connects the switch of cooling tower and cooling water pump respectively.
Compared with prior art, the utility model can protect the operation of the cooling system of freezing unit and freezing machine host
Synchronization is held, serves energy-saving effect；Employ on refrigerator it is existing upload with run signal contact, thus need not enter
Capable investment construction again, it is cost-effective.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marked in figure：1st, cooling tower, 2, cooling water pump, 3, freezing machine host, 4, chilled water pump, 5, air-conditioning box, 6, upper

Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with the utility model
Implemented premised on technical scheme, give detailed embodiment and specific operating process, but guarantor of the present utility model
Shield scope is not limited to following embodiments.
It is used to freezing the energy-saving control system of cooling system in unit as shown in figure 1, a kind of, including host computer 6 and all connects
The freezing machine host 3, cooling water pump 2 and cooling tower 1 of host computer 6 are connect, the coolant outlet of freezing machine host 3 passes through cooling water pump
The entrance of 2 connection cooling towers 1, the cooling water inlet of the outlet connection freezing machine host 3 of cooling tower 1；Freeze machine host 3 include according to
Evaporator 8, compressor 9 and the condenser 7 of secondary connection, coolant outlet and cooling water inlet are located on condenser 7.
Condenser 7 is connected with evaporator 8 by the pipeline provided with choke valve 10.
The chilled water outlet and entrance of evaporator 8 connect the corresponding gateway of chilled water of air-conditioning box 5 respectively.Wherein, evaporate
The chilled water outlet of device 8 is connected by chilled water pump 4 with the chilled water inlet of air-conditioning box 5.
When the work of machine host 3 is freezed, compressor 9 constantly takes refrigerant vapour away from evaporator 8, due to pressure
Contracting machine 9, which extracts refrigerant vapour, reduces the pressure of evaporator 8, makes in evaporator 8 remaining refrigerant in relatively low temperature
Explosive evaporation is spent, the heat that recirculated water in heat-transfer pipe is drawn in refrigerant vaporization is allowed to cool, and obtains required 7~12 degrees Celsius
Chilled water, then by chilled water pump 4, get to workshop air-conditioning box 5, reach the purpose to workshop cooling.
After the heat for drawing recirculated water, refrigerant vapour is inhaled into compressor 9 and compressed, refrigerant temperature liter after compression
Height, discharge from compressor 9, condensed into condenser 7.Cooling water enters the phase after cooling tower 1 cools down by cooling water pump 2
Temperature is reduced, the copper pipe of condenser 7 is flowed through, takes away the heat of gaseous refrigerant, be allowed to become liquid, then liquid refrigerant
Throttled after flowing through choke valve 10, come back to evaporator 8 and carry out low-temp low-pressure evaporation, continue kind of refrigeration cycle.
The communication of itself run signal is arrived host computer 6 by freezing machine host 3 by RS485 interfaces, while by cooling tower 1
The opening of blower fan and cooling water pump 2, stop signal and be connected with host computer 6.The specific work process of this control system is as follows：Work as refrigerator
When main frame 3 is opened, host computer 6 detects the run signal of freezing machine host 3, postpones certain time, it is preferred that after delay 30s,
The blower fan of cooling water pump 2 and cooling tower 1 is opened；When freezing the closing of machine host 3, host computer 6 detects freezing machine host 3
Run signal stops, and postpones certain time, it is preferred that and after delay 60s, the blower fan of cooling water pump 2 and cooling tower 1 is out of service,
Operation useless for a long time is avoided, reaches the purpose of energy-conservation.
