It in existing trilogy supply hot and cold water heat pump machine system, is recycled with a driven compressor system refrigerant, system
Middle configuration hot water heat exchanger, evaporator, cold-water heat exchanger, when single water heating or single hot and cold water, cold-water heat exchanger or hot water are changed
Hot device does not make condenser system and is easy non-equilibrium state, leads to the problem that system is unstable.The present invention is by air-conditioning and hot water machine two
System is relatively independent and involves the thinking of auxiliary mutually, and the evaporator of the condenser of air-conditioning and hot water machine is combined into one, and point
Belong to two independent refrigeration systems, be equivalent to and be combined together the evaporator of two independent refrigeration systems with condenser,
Keep total system more optimized.
Moreover, heat exchanger specification is that 4 rows are in-line, fork is arranged, 25 pitch-rows, two circuits are bridged using integral fins, and lead to
It crosses and designs that small U is curved and its connection type, so that the pipeline of this heat exchanger is interlocked, and the first heat exchange branch is propped up with the second heat exchange
Adverse current, these designs improve cold and hot complementary efficiency each other on road.In order to guarantee being uniformly distributed for refrigerant, design of heat exchanger is in pairs
Three into three go out structure, and overall performance is optimal.
Evaporator of the heat exchanger as hot water machine, while the condenser as air conditioner, are mounted on room by piping connection
In outer machine.Heat exchanger applications also solve that oil return, overheat, defrosting, Load Regulation of system unit etc. are a series of to ask on product
Topic.
This air-source multiple-supplying air conditioner water heating machine is 3 fixed frequency air conditioner hot water machines, can be using Expanding design as frequency conversion, high temperature ring
A variety of series of products such as border, low temperature environment, 1-12HP.The component can be used for cascade refrigeration equipment and dehumidifier produces
On product.
Product of the present invention has it scientific and advanced.
It is scientific: to pass through the cold of the air-cooled type fin tube type to beauty, Gree and hot water machine special manufacturer three same levels
Condenser and evaporator carry out actual test, be designed according to heat transfer and channel theory knowledge further according to the parameter of test
Calculation review, calculated result includes the coefficient of heat transfer, length of tube, number of fins, material cost etc., and carries out Comprehensive Correlation, herein
On the basis of preferably go out optimum tube diameter, pipe away from, a pitch of fins, piece is wide, flows to and flows to path element parameter etc., by air-source trilogy supply
Air conditioner water heating machine using new function, design cold and hot bridge joint and become function evaporative condenser, and in novel air source trilogy supply
Practical application is carried out in air conditioner water heating machine unit.
Advanced: the works are designed the cold and hot complementary function that becomes on the fin tube type surface-type heat exchanger generally used and are steamed
Feel cold condenser, belongs to innovative design, and compared with traditional superposition type evaporative condenser, the structure of the latter can only be bushing type, pipe
Shell-type and sprinkle sprinkle formula, are used only in the cold and hot exchange or central air-conditioning of cascade refrigeration, and the works pass through fin
Design staggered with pipeline is bridged, cold and hot complementary high efficient heat exchanging is realized, can be used for cascade refrigeration, dehumidifier, particularly answer
The conversion of the multiple functions such as heat exchange area multiplication, complementary defrosting, accumulation of energy heating is realized in the system of new air-source trilogy supply,
Input " evaporating condensation heat exchanger ", " high-performance heat exchanger ", " superposition type heat exchanger ", " multifunctional heat exchanger ", " cold and hot mutual replacement
National IP Network in the keyword searches Chinese patent net such as hot device " and CNKI, there are no the inventions of any works or the similar works
And design studies.
Although an embodiment of the present invention has been shown and described, those skilled in the art should understand that: not
A variety of change, modification, replacement and modification can be carried out to these embodiments in the case where being detached from the principle of the present invention and objective,
The scope of the present invention is limited by claim and its equivalent replacement, without creative work improvements introduced etc., should all be wrapped
Containing within protection scope of the present invention.
