Branch road 40 is in parallel with heat-recovery condenser 30, and is connected between refrigerant exit and main condenser 20, and branch road control valve 50 is arranged
On bypass branch 40 and 40 break-make of bypass branch can be controlled.By a bypass branch in parallel on heat-recovery condenser 30
40, and the break-make that valve 50 controls bypass branch 40 is controlled using branch road, in this way, can control coolant as needed is
No stream enters heat-recovery condenser 30.When heat-exchange system just starts, in order to prevent coolant and water in heat-recovery condenser 30
The refrigerant temperature that (or other heat transferring mediums) heat exchange is caused entry in main condenser 20 is too low, and branch road control valve 50 is opened, and is bypassed
Branch road 40 is connected, and is made coolant bypass heat-recovery condenser 30, is directly entered main condenser 20, when starting so as to solve heat-exchange system
As the too low system for causing of the refrigerant temperature into main condenser 20 reports an error the problem of shutdown.
As shown in Figures 2 and 3, heat-exchange system also includes gas-liquid separator 100, and gas-liquid separator 100 is connected with compressor 10
Connect.Gas-liquid separator 100 is used to make gaseous coolant separate with liquid refrigerants, prevents liquid refrigerants from entering in compressor 10 to compression
Machine 10 causes to damage.Gas-liquid separator 100 is arranged on the side of compressor 10, and is connected with compressor 10 by pipeline.
Preferably, main condenser 20 and/or heat-recovery condenser 30 are double-tube heat exchanger.Main condenser 20 and recuperation of heat are cold
Condenser 30 can reduce space hold while heat transfer effect is guaranteed using double-tube heat exchanger.
As shown in Fig. 2 heat-exchange system also includes recuperation of heat water route 60, recuperation of heat water route 60 is connected with heat-recovery condenser 30
Connect, and exchange heat with the coolant in heat-recovery condenser 30.Water or other media and heat-recovery condenser in recuperation of heat water route 60
30 connections, water or other media are exchanged heat with coolant in heat-recovery condenser 30, absorb the heat of coolant, afterwards by hot water or liter
Other media after temperature are conveyed to heating equipment 90.
The coolant flowed out from heat-recovery condenser 30 enters main condenser 20.Heat-exchange system also includes main heat exchange water route,
Main heat exchange water route is connected with main condenser 20, and is exchanged heat with the coolant in main condenser 20.Water in main heat exchange water route or other
Medium is exchanged heat with the coolant in main condenser 20.
Recuperation of heat water route 60 is separated with the main heat exchange water route of system.Water or other media in recuperation of heat water route 60 individually with
Heat-recovery condenser 30 is exchanged heat.Water or other media in main heat exchange water route is exchanged heat with the coolant in main condenser 20.Heat
Reclaiming condenser 30 and main condenser 20 is connected together by refrigerant pipeline.
In the present embodiment, heat-exchange system also includes vaporizer 70 and restriction 80, and vaporizer 70 is double-tube heat exchanger, is steamed
Send out device 70 to be connected with main condenser 20.Restriction 80 is connected between main condenser 20 and vaporizer 70.
In order to monitor the refrigerant temperature into main condenser 20, heat-exchange system also includes temperature detector, temperature inspection
Survey device to be arranged at the refrigerant import of main condenser 20, and detect the refrigerant temperature into main condenser 20.
In order to control as needed, heat-exchange system also includes control unit, and control unit is connected with temperature detector, and root
Opening or closing for valve 50 is controlled according to the detection temperature controlling brancher of temperature detector.
During work:
When heat-exchange system brings into operation it is also unstabilized when, branch road control valve 50 is opened, bypass branch 40 and heat exchange system
System water route first leads to, and heat-recovery condenser 30 does not temporarily work, and water and coolant enter main condenser 20, are exchanged heat, after heat exchange, cold
Matchmaker reduces through restriction 80, pressure, through vaporizer 70, finally enters compressor 10.
After heat-exchange system is stable, the ice-forming processes outside pipes of temperature detector automatic detection main condenser 20 work as temperature
When degree is more than certain value, now heat-exchange system temperature tends to balance state, and branch road control valve 50 cuts out, and bypass branch 40 disconnects,
Through heat-recovery condenser 30, heat recovery function is enabled the water and coolant of recuperation of heat, enters back into main condenser 20, then Jing afterwards
Restriction 80, vaporizer 70 are crossed, compressor 10 is finally entered.In this structure, heat-recovery condenser 30 is used to meet recuperation of heat work(
Can require, on heat-recovery condenser 30, a bypass branch in parallel, controls 50 automatic control of opening/closing of valve by branch road, so as to change
The trend of water, solves system because 20 inlet temperature of main condenser is too low, and heat transfer effect is poor, the problem of system autostop.
In other embodiments, heat-recovery condenser 30 and main condenser 20 can be configured according to practical situation, as long as making
Heat-recovery condenser 30 is used for recuperation of heat, and main condenser 20 is used for system and normally runs.
According to a further aspect in the invention, there is provided a kind of air-conditioner, the air-conditioner include above-mentioned heat-exchange system.Using upper
The air-conditioner of heat-exchange system is stated, while being adjusted to air can be carried out recuperation of heat, and just bring into operation in air-conditioner
Stage do not start heat recovery function, it is ensured that functional reliability, prevent stopping alarm.
Heat-exchange system of the invention has the following technical effect that:
By a bypass branch in parallel on heat-recovery condenser, and a branch road control is set on bypass branch
Valve, when system brings into operation it is also unstabilized when, branch road control valve is opened, coolant and water without heat-recovery condenser, directly
Tap into into main condenser, that is to say, that when system just brings into operation, recuperation of heat does not work.After system run all right, it is
The refrigerant temperature of the refrigerant import of system automatic detection main condenser, when more than certain setting value, branch road control valve cuts out,
Coolant and water are introduced into heat-recovery condenser, and now recuperation of heat starts to start, and cold water is exchanged heat with heat-recovery condenser, reclaims hot water
Use for residential households.If the system detects that when the refrigerant temperature of the refrigerant import of main condenser is less than certain value, branch road
Control valve is again turned on, and recuperation of heat suspends use.Thus solve when the heat-exchange system with recuperation of heat sleeve pipe runs, to report automatically what is stopped
Problem.Realize the heat recovery function of system, it is to avoid because refrigerant temperature it is too low, heat transfer effect difference and report automatically and stop.And system only increases
Plus 1 bypass branch, and by branch road control valve control, simple possible.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
