Description
Technical field
The utility model relates to a kind of central air-conditioning ice storage technology, relates in particular to a kind of central air-conditioning double evaporators ice cool-storage type source pump.
Background technology
Energy scarcity is the problem that the our times various countries are faced jointly, and the ice cold-storage has more and more widely application as one of important energy-conservation means of new century.Ice-storage system is in the electrical network valley power consumption period at night, opens the ice storage air conditioner main frame, and ice making stores, electrical network peak period by day, molten ice is put cold, to satisfy the requirement of building air-conditioning or production technology, can adopt multiple modes such as ice hockey ice-reserving, melt ice on coil ice-reserving, water ice-reserving.Thereby reach the peak-valley difference of the electricity consumption of transfer electrical power peak, balance electrical network, utilize peak valley electric power price difference to reduce the effect of operation of air conditioner expense.Ice cool-storage type source pump is a kind of have refrigeration, heat-production functions and Trinitarian water source heat pump units of ice-reserving function; because main process equipment should freeze, heat ice-reserving again; so unit need carry out the design of three operating modes; and on performance design such as system, control and safeguard protection, take into full account the application of ice cold-storage, real realize refrigeration, heat the perfect adaptation with ice-reserving.
Present ice cool-storage type source pump adopts shared evaporimeter unit usually, be unit the standard refrigeration, heat with the ice-reserving operating mode under all use same evaporimeter, because evaporimeter is shared, the refrigerating medium of anti-icing fluid type is in ice-melt, freeze, need when heating to change and the user side heat exchange by the secondary water pump plate of flowing through.The advantage of this way is that set structure is simple relatively, and control realizes that easily the unit cost is lower, and shortcoming is no matter unit is that refrigerating operaton or ice cold-storage operation refrigerating medium all are the water that has antifreezing agent.Because the heat exchange efficiency of antifreezing agent is low, viscosity is big, thereby will cause the unit phenomenon that efficient reduces and chilled water water pump wasted work increases when refrigerating operaton, for shared evaporimeter unit, during the system standard refrigeration, need the secondary pump system, be that plate water-change pump and user side water pump all need to open, the water pump power consumption increases.
Also there is the hidden danger of refrigerating medium accidental release polluted source in the shared evaporator system of ice cool-storage type source pump.
The utility model content
The purpose of this utility model is to provide a kind of double evaporators ice cool-storage type source pump, and source pump efficient when refrigerating operaton is low in the solution prior art, and chilled water water pump wasted work increases and water top-cross fork pollution problems.
In order to achieve the above object, the utility model adopts following technical scheme: described double evaporators ice cool-storage type source pump comprises: a refrigerating evaporator, one ice-reserving evaporimeter, two evaporator places are equipped with magnetic valve and throttling arrangement, pressure duct is told two branch roads and is linked to each other with the ice-reserving magnetic valve with the system water solenoid valve respectively behind the dry filter device, the low pressure tracheae parallel connection of two evaporator outlets is joined with the compressor connector after connecing an oil return apparatus for deivation, system be provided with system water solenoid valve and ice-reserving magnetic valve to refrigeration, heat with the ice-reserving process and control.
According to unit operation mode of operation needs, the operation mode of operation is: freeze, heat, three kinds of patterns of ice-reserving, because being the water route, described source pump switches unit, refrigeration work mode user side water route links to each other with evaporimeter, water source or ground source are connected with condenser, heat user side water route, switching back, mode of operation water route and link to each other with condenser, and water source or ground source are connected with condenser, so freezing, heating under the mode of operation, the agent of unit internal refrigeration storage flows to consistent all the time.Promptly when selecting refrigeration or heating mode of operation, the system water solenoid valve is opened, the ice-reserving closed electromagnetic valve, and high-pressure refrigerant drying filter flows to refrigerating evaporator; When selecting the ice-reserving mode of operation, the ice-reserving magnetic valve is opened, and the system water solenoid valve is closed, and high-pressure refrigerant drying filter flows to the ice-reserving evaporimeter.Be connected with the compressor connector after the parallel connection of two evaporator outlet low pressure tracheaes, be provided with at two evaporator outlets place in parallel and induce oil return apparatus,, improve the cold-producing medium flow velocity, the lubricating oil at least favorable dot product oil place is taken back compressor by changing refrigerant flow direction.
Compare with prior art, the utlity model has following advantage:
Adopt that two separate refrigeration and ice-reserving evaporator system freeze, heat, the ice-reserving mode operation, avoid the refrigeration of directly using shared evaporimeter to cause, the adverse effect that anti-icing fluid refrigerating medium heat exchange efficiency is low when heating, viscosity causes system effectiveness decline, water pump wasted work to increase greatly, also avoided using the cross pollution when hot and cold switching of side and water source side, or the refrigerant side pollutes the adverse effect of underground water etc. because of booster.

Figure 2 shows that system flow chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, specify the utility model.
The double evaporators ice cool-storage type source pump that the utility model relates to comprises: an ice-reserving evaporator system 15, one dry filter device 14, one high-pressure fluid common interface 16, one low-pressure fluid common interface 17, an one oil return apparatus for deivation 18 and a compressor connector 19, wherein said high-pressure fluid common interface 16 1 ends link to each other with dry filter device 14, one end is told two branch roads, branch road one connects 112 imports of system water solenoid valve, branch road two connects 152 imports of ice-reserving magnetic valve, 112 outlets of system water solenoid valve link to each other with 113 imports of system water throttling arrangement, 113 outlets of system water throttling arrangement are connected in refrigerating evaporator 111 imports, 152 outlets of ice-reserving magnetic valve link to each other with 153 imports of ice-reserving throttling arrangement, 153 outlets of ice-reserving throttling arrangement are connected in 151 imports of ice-reserving evaporimeter, described refrigerating evaporator 111 and the 151 outlet parallel connections of ice-reserving evaporimeter all are connected to low-pressure fluid common interface 17, circulation and circulation that described system water solenoid valve 112 and 113 controls of system water throttling arrangement enter the refrigerating evaporator cold-producing medium, circulation and circulation that described ice-reserving magnetic valve 152 and 153 controls of ice-reserving throttling arrangement enter the ice-reserving evaporator refrigerant.
