Abstract
The utility model discloses a kind of dual protection type high-temperature air conditioner unit; mainly comprise condenser, expansion valve, running protection controller, safety protection controller, gas-liquid separator, compressor, frequency conversion fan, evaporimeter; its design feature is: condenser connects expansion valve; expansion valve connects evaporimeter; evaporimeter connects gas-liquid separator; gas-liquid separator connects compressor; compressor connects condenser; evaporimeter side arranges frequency conversion fan; running protection controller and safety protection controller are arranged between compressor and condenser, control whole air-conditioner set.Technique effect of the present utility model is: solve air-conditioner set in use can not in hot environment the deficiency of safe continuous working.
Description
Technical field
The utility model relates to a kind of air-conditioner set, particularly relates to a kind of dual protection type high-temperature air conditioner unit.
Background technology
Air-conditioner set mainly refers to that refrigeration system is main, i.e. such as water cooled chiller, air handpiece Water Chilling Units etc.And sometimes also claiming whole system, such as whole central air conditioner system is air-conditioner set, if small-sized (family expenses), then refers generally to entirety.At present; conventional air-conditioning unit is made up of condenser, expansion valve, pressure controller, gas-liquid separator, compressor, evaporimeter etc.; when this air-conditioner set generally uses in hot environment, compressor exhaust temperature can be very high, and pressure at expulsion also can be very high, when compressor is at high pressure at expulsion longtime running; the life-span of compressor can be affected; meanwhile, when pressure at expulsion is too high, pressure controller can carry out high voltage protective; use compressor shutdown, such unit just can not run continuously.
Summary of the invention
The purpose of this utility model there are provided a kind of dual protection type high-temperature air conditioner unit, overcome existing air-conditioner set can not in hot environment safe continuous working not enough.
The utility model is achieved like this, a kind of dual protection type high-temperature air conditioner unit, mainly comprise condenser, expansion valve, running protection controller, safety protection controller, gas-liquid separator, compressor, frequency conversion fan, evaporimeter, it is characterized in that: condenser connects expansion valve, expansion valve connects evaporimeter, evaporimeter connects gas-liquid separator, gas-liquid separator connects compressor, compressor connects condenser, evaporimeter side arranges frequency conversion fan, running protection controller and safety protection controller are arranged between compressor and condenser, control whole air-conditioner set.
Air-conditioner set design and operation protection controller of the present utility model, safety protection controller; running protection controller break-make force value is 2.3/2.8Mpa; safety protection controller break-make force value is 3.1/2.8Mpa; when unit operation; when Compressor Discharge Pressure is more than 2.6Mpa; running protection controller action, makes frequency conversion fan reduce frequency.
Technique effect of the present utility model is: solve air-conditioner set in use can not in hot environment the deficiency of safe continuous working.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the drawings, 1 condenser, 2 expansion valves, 3 running protection controllers, 4 safety protection controllers, 5 gas-liquid separators, 6 compressors, 7 frequency conversion fans, 8 evaporimeters.
Detailed description of the invention
As shown in Figure 1, the utility model is achieved like this, dual protection type high-temperature air conditioner unit is by condenser 1, expansion valve 2, running protection controller 3, safety protection controller 4, gas-liquid separator 5, compressor 6, frequency conversion fan 7 and evaporimeter 8 form, it is characterized in that: condenser 1 connects expansion valve 2, expansion valve 2 connects evaporimeter 8, evaporimeter 8 connects gas-liquid separator 5, gas-liquid separator 5 connects compressor 6, compressor 6 connects condenser 1, evaporimeter 8 side arranges frequency conversion fan 7, running protection controller 3 and safety protection controller 4 are arranged between compressor 6 and condenser 1, control whole air-conditioner set.
Air-conditioner set design and operation protection controller 3, safety protection controller 4, running protection controller 3 break-make force value is 2.3/2.8Mpa, safety protection controller 4 break-make force value is 3.1/2.8Mpa, when unit operation, when compressor 6 pressure at expulsion is more than 2.6Mpa, running protection controller 3 action, frequency conversion fan 7 is made to reduce frequency, the suction temperature of such evaporimeter 8 reduces, compressor 6 pressure at expulsion reduces, unit just can work under lower pressure at expulsion, improve the service life of compressor, simultaneously, also can ensure that unit will make safety protection controller 4 action cause shutting down more than 3.1Mpa because of pressure at expulsion, such unit just can continuous operation.
