Background technology
Ice-storage air-conditioning typically refers to: consume the electric refrigeration ice-reserving when the electrical network low ebb, air-conditioning equipment used when its cold was stored the power supply network peak.The kind of ice-chilling air conditioning system is a lot, and whether classification is also quite complicated, by using refrigerating medium can be divided into ice making of the direct expansion and indirect evaporation ice making.
The indirect evaporation ice-making system is to introduce refrigerating medium to transmit heat in the kind of refrigeration cycle process.What use always in ice-storage air-conditioning system is glycol water (expensive glycol water has certain corrosivity).Conventional indirect evaporation ice-making system needs the secondary heat transmission equipment, and (heat transmission equipment is cold-producing medium-refrigerating medium heat exchanger, secondary heat exchange equipment is refrigerating medium-water-to-water heat exchanger), this causes equipment building block and occupied ground to increase, the also corresponding raising with maintenance cost of initial cost simultaneously.
The ice making of the direct expansion system is common borneol landing formula ice machine, and the type ice machine with the water in the Ice Storage Tank, from up to down is sprayed at the tabular evaporator surface of ice machine by water pump, makes it be frozen into ice sheet.When ice layer thickness reached certain hour, by the cross valve on the ice machine, with the part high temperature refrigerant gas feeding evaporimeter of compressor outlet, then the ice-out that contacts with the evaporator plate face leaned on the self gravitation landing to cold-storage groove.There is following defective in this system: the height to the machine room place has higher requirements, and the ice making main frame need be arranged on directly over the cold-storage groove, makes two-layer layout; Utilize the high temperature hot gas ice-melt, need to consume cold storage capacity as cost, very uneconomical.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of making apparatus simple, the economical and practical direct vaporation-type ice-storage air-conditioning of unsteady flow amount intelligence control system.
The technical scheme that its technical problem that solves the utility model adopts is: the direct vaporation-type ice-storage air-conditioning of a kind of unsteady flow amount intelligence control system, comprise refrigeration host computer, described refrigeration host computer comprises gas-liquid separator, compressor, oil eliminator, condenser, reservoir, device for drying and filtering, magnetic valve, the heating power expansion valve of order pipeline connection successively; It is characterized in that: also comprise an Ice Storage Tank, be provided with evaporation coil in the described Ice Storage Tank, described evaporation coil, heating power expansion valve, gas-liquid separator are interconnected respectively;
Described evaporation coil also is connected with a water pump, check valve, fan coil successively, and described fan coil inserts described evaporation coil again, and four form the loop;
One ice-reserving amount detector also is set in the described Ice Storage Tank, and described ice-reserving amount detector, water pump electrically connect a controller respectively.
Preferably, described evaporation coil is that metal material is made.
Preferably, between described water pump and the check valve, between described check valve and the described fan coil, between described fan coil and the described evaporation coil proportional integral control valve is installed respectively.
Compared with prior art, the beneficial effects of the utility model are: because the air-conditioning backwater directly contacts with the ice sheet of evaporation of metal coil surface, and good effect of heat exchange, it is fast to get speed of cooling, can hang down from the supply water temperature of Ice Storage Tank to reach about 1 ℃; The idle call chilled water is directly from Ice Storage Tank, so can not need secondary heat exchange equipment; One cover ice making main frame can connect many cover Ice Storage Tank and terminal units thereof simultaneously, regulates cold-producing medium trend, flow and terminal unit with chilled water trend, the flow high-energy utilization rate with the assurance whole system by controller according to different loads.In addition, ice layer thickness can reach more than 30 millimeter, and the unit cold storage capacity is also bigger, and it is also longer to release cool time, has avoided utilizing the cold of a part of system that the high temperature hot gas ice-melt consumed simultaneously.
