This total heat recovery air conditioner refrigerating simultaneously water heating when, four-way change-over valve must not electricity, the second valve, the second electronics
Expansion valve is in full off state, and air cooled condenser electric must not work, and the first valve is in opening, and flow control valve is opened
Open so that cooling water enters water cooled condenser.
This total heat recovery air-conditioning, when storage tank is full or does not need water heating, is to ensure that summer air-conditioning can keep making always
It is cold to waste while being unlikely to allow hot water directly to drain, the first valve can be closed, the second valve, the second electric expansion valve is opened
Being shown in a fully open operation no throttling action, closing flow control valve does not allow cooling water to enter water-cooled condenser, while enabling air-cooled
Condenser carrys out work.
When this total heat recovery air-conditioning winter room is heated, four-way change-over valve obtains electric commutation, the second valve, the second electronics
Expansion valve is shown in a fully open operation no throttling action, and air cooled condenser obtains electric work, and the first valve is closed, flow
Regulating valve is closed cooling water and is not entered water cooled condenser.
When this total heat recovery air-conditioning winter independent water heating, four-way change-over valve must not electricity, the second valve opening, second
Electric expansion valve is in running order throttling action, and air cooled condenser obtains electric work, and the first valve is closed, stream
Adjustable valve is opened, and cooling water enters water cooled condenser, and the corresponding blower fan of vaporizer electric must not work, and vaporizer does not have substantially
There is heat exchange, the first electric expansion valve is shown in a fully open operation no throttling action.
Two neighboring aluminium sheet rotation 180 degree is placed so that the groove position one of adjacent two panels aluminium sheet is in the first from left on the right side
It is alternately arranged, all of aluminium sheet is inserted on shell, therefore cooling water is entered by cooling water inlet, subsequently between adjacent two blocks of aluminium sheets
Serpentine-like flowing in gap, cooling water are fully contacted heat exchange with every block of plate.Refrigerant import is leaned near coolant outlet, coolant liquid outlet
Nearly cooling water inlet, coolant and cooling water reverse flow heat exchange, coolant are more and more lower from import to outlet temperature, and cooling water is from entering
Mouth arrives outlet temperature more and more higher, can guarantee that two kinds of fluid temperature differences, is conducive to strengthening heat exchange.Between every aluminium sheet, distance can simultaneously
It is smaller to arrange, it is ensured that cooling water can also have larger flow velocity under less flow, be conducive to heat exchange, while every aluminium sheet
The position for being embedded with copper pipe is raised, is also beneficial to increase the disturbance of cooling water, improves the coefficient of heat transfer.
If walking coolant copper pipe and being directly contact with cooling water, once perforation, water enters compressor, and compressor will be reported
Give up, or even complete equipment can all be damaged, and the heat exchanger of this patent design is wrapped up by aluminium sheet due to copper pipe, without straight with cooling water
Contact, copper pipe will not be corroded perforation substantially, in the area that water quality is very poor, can increase magnesium rod, using sacrificial in heat exchanger
The cathode protection method of domestic animal anode can also be plated one layer of anti-corrosion material in addition on aluminium sheet and strengthen anti-corrosion being protected aluminium sheet and copper pipe.
The flow for adjusting Flux Valve Control cooling water and then the leaving water temperature for adjusting cooling water can be passed through, leaving water temperature should not mistake
Height, is primarily due to the high incrustation scale of temperature and is also easy to produce, and whole heat exchanger heat transfer effect is not good, is unfavorable for energy-conservation.Use time
After longer, all aluminium sheets all can be taken out, clean shell and aluminium sheet, be easy to safeguard, if desired for replacing or reduction aluminum plate
Number, is convenient to.
As a example by total heat recovery air-conditioning with refrigerating capacity as 1P, using the water cooling heat exchanger in the present invention, can be adjusted by flow
In the range of the flow and then control hot water preparing temperature 45-65 DEG C of section valve regulation cooling water, when 55 DEG C of hot water is produced, hot water stream
Amount can reach 120L/min, and integrated system synthesis COP reaches more than 7.
