The limitation of control panel temperature so that this programme can effectively control to enter in indoor machine evaporation
The temperature of coolant, and then ensure that indoor temperature can reach preset requirement.
Below will be based on constant temperature dehumidification pattern, cooling in summer pattern and winter heating's pattern to the present invention
The carrying out practically process of the type constant temperature dehumidifying air conditioner in embodiment illustrates.
Example one: constant temperature dehumidification pattern
With reference to the constant temperature dehumidification mode operation figure shown in Fig. 4, cross valve runs refrigeration mode, with reference to figure
In the direction of arrow, coolant is flowed to cold by the second interface and the 3rd interface through cross valve in compressor
Condenser, after circulation, this coolant is connect through the first of cross valve by the second vaporizer section in indoor set
Mouth and the 4th interface flow to compressor through reservoir, carry out circulation next time.Concrete, this electricity
Sub-expansion valve 1 standard-sized sheet, without throttling action, indoor fan 1 runs, and dehumidification valve is energized, in indoor set
Can only be connected by dehumidification valve between first vaporizer section and the second vaporizer section, dehumidification valve produces throttling
Effect, in indoor set, the first vaporizer section coolant adds hot-air, and the second vaporizer section refrigerant evaporation is to sky
Air cooling dehumidifies, and air humidity after indoor set reduces, and reaches the purpose of indoor air dehumidification.?
During type constant temperature dehumidifying air conditioner dehumidifies, this indoor temperature can raise, reduce or keep basic
Constant, the control of indoor leaving air temp is by regulation outdoor fan 2 rotating speed and electric expansion valve 2 aperture
Realize.
Concrete, when indoor temperature needs to reduce, outdoor fan 2 runs higher wind, and electronics is swollen
Swollen valve 2 aperture is less, off-premises station High Temperature High Pressure coolant most or all through outdoor condenser, cold
The coolant that temperature of congealing into is relatively low, is flowed out by electric expansion valve 1, with the temperature from electric expansion valve 2
Spend the mixing of high coolant or flow directly into indoor machine evaporation, cold hence into indoor machine evaporation
Matchmaker's temperature is relatively low, and in indoor set, that air adds heat is the most less for the first vaporizer section, it is achieved indoor go out
Air temperature is relatively low.
When indoor temperature needs to raise, outdoor fan 2 runs relatively low wind speed, and electric expansion valve 2 is opened
Degree is relatively big, and the coolant of off-premises station High Temperature High Pressure is partly into condenser, is condensed into relatively low cold of temperature
Matchmaker, is flowed out by electric expansion valve 1, and the coolant that a part of High Temperature High Pressure temperature is higher directly passes through side
Logical electric expansion valve 2 flows out, and is mixed into, with another part, the coolant that temperature is higher, so, enters
The refrigerant temperature of indoor machine evaporation is higher, and indoor first vaporizer section adds heat the most relatively to air
Many, it is achieved indoor leaving air temp is higher.
Thus, under constant temperature dehumidification pattern, outside to outdoor fan 2 rotational speed regulation and control room
Electric expansion valve 2 aperture, it is achieved room air adds the regulation of heat, can effectively realize indoor wet
Degree reduces, and temperature can raise, reduces or be basically unchanged, it is possible to the environment being suitable for wider range is warm and humid
Degree change, thus improve indoor temperature and humidity and control accuracy and comfortableness.
Example two: refrigeration mode
Referring still to Fig. 4, cross valve runs refrigeration mode, with reference to the direction of arrow in figure, coolant by
In compressor, the second interface and the 3rd interface through cross valve flow to condenser, after circulation, and should
Coolant by the second vaporizer section in indoor set through the first interface of cross valve and the 4th interface through supercool
Night, separator flowed to compressor, carried out circulation next time.Indoor dehumidification valve power-off path, dehumidification valve
Without throttling action, in indoor set, vaporizer is all as refrigeration purposes, and electric expansion valve 2 completely closes,
Electric expansion valve 1 controls flow according to suction superheat or delivery temperature, off-premises station blower fan 2 fortune at a high speed
OK, it is achieved indoor refrigeration purpose.
Example three: heating mode
With reference to the heating mode service chart shown in Fig. 5, cross valve runs heating mode, with reference in figure
The direction of arrow, coolant is flowed to evaporation by compressor through the second interface of cross valve and first interface
Device, after circulation, this coolant by condenser in off-premises station through the 3rd interface and the 4th of cross valve
Interface flows to compressor through supercool midnight from device, carries out circulation next time.Indoor dehumidification valve power-off is led to
Road, dehumidification valve is without throttling action, and indoor machine evaporation is all as heating purposes, and electric expansion valve 2 is complete
Contract fully, electric expansion valve 1 controls flow, outdoor fan 2 according to suction superheat or delivery temperature
High-speed cruising, it is achieved indoor heating purpose.
