For source of sewage+air-source scheme for combining, traditional ultralow temperature double source bathing heat pump unit include refrigeration mode, heating mode,
Heat recovery mode and water heater mode.Bathing industry only uses heat recovery mode therein and water heater mode, above-mentioned ultralow temperature
It in double source bathing heat pump unit, needs to shut down in mode handover procedure, it is frequent to result in unit for frequent switching working mode
Switching on and shutting down, have a significant impact for the service life of other associated components such as compressor, unit valve member, water pump.
Total heat recovery is divided into two kinds at present, and one kind is tandem total heat recovery, and one kind is parallel total heat recovery, tandem
Total heat recovery when refrigeration is with heating, connect a heat regenerator always, and droop loss is larger, due to the volume of fin by high-pressure side
It is larger, a biggish liquid storage device and charging amount are needed, is not a kind of efficient operating scheme, does not accomplish the most Canon of design
Effect, using the scheme of parallel heat regenerator, needs to solve the problems, such as the airtightness and internal leakage of multiple solenoid valves.
(" CN201320863387- is a kind of with the patent of invention of McQuay for parallel ultralow temperature double source bathing heat pump unit
Ultralow temperature double source bathing heat pump unit-invention ") for use two four-way valves, solve the problems, such as shut down switching, may be implemented
Heat recovery mode and water heater pattern switching are not shut down.But there are an apparent defects for the patent of invention, it is impossible to pass through
Switch the mutual conversion that 4WV2 completes water heater mode and heat recovery mode, what traditional ultralow temperature double source bathing heat pump unit used
Environment temperature is -10 DEG C~43 DEG C, has not adapted to northern area use, conventional parallel or series connection ultralow temperature double source bathing heat
For pump assembly in recuperation of heat or water heating since leaving water temperature is higher, pressure difference is larger, and delivery temperature is higher, in order to guarantee compressor
A well matched liquid-jet device is operated normally, being forced to compressor feed flow reduces delivery temperature.
(" CN205580024U- one kind is super with the patent of invention of modern Lay grace for parallel ultralow temperature double source bathing heat pump unit
Low temperature total heat recovery Air-Cooled Heat Pump Unit-invention ") for, by applying birotor tonifying Qi spray liquid enthalpy gain compressor, four-way is transformed
1. valve with four-way valve, solves the problems, such as that compressor does not shut down switching.Solve the problems, such as low circumstance temperature application, but due to washing
Bath type sewage recycles the characteristics of unit, and sewage recovered temperature is higher, above-mentioned ultralow temperature total heat recovery type unit, in low circumstance temperature operating condition
Under, the problem of refrigerant migration, limits the high efficiency of wastewater ocean disposal, is difficult to play the advantage of sewage, above-mentioned ultralow temperature
Scheme, the economizer control program of use are difficult to be that degree of supercooling reaches maximum, the present invention draws due to there is the presence of heat transfer temperature difference
Enter flash tank, eliminate heat transfer temperature difference, is improved unit performance.
Therefore, a kind of elimination heat transfer temperature difference is designed to overcome the shortcomings of above-mentioned technology, promotes heat exchange property, enlarger
Group use scope extends press and unit service life, and stability is high, and sewage operating condition is more efficient, realizes the heat pump of double source operation
Unit, exactly inventor problem to be solved.
