So it is outdoor that this kind unit can't be placed on, must be placed in the machine room of ground machine room lower or independent building.And must warming, fire-fighting and ventilation equipment etc. be installed according to " machine room architectural control standard " in the machine room, must make the unit ambient temperature greater than 0 degree, both taken a large amount of land use areas, consume great amount of manpower and material resources and financial resources again, and handle construction again, elaborate formalities such as examine.
Even be installed in the suitable machine room, after lithium bromide absorption cold in the past/warm water unit normally diluted shutdown, solution concentration and was retained a large amount of water as refrigerants greatly about about 55% in the evaporimeter.The winter low temperature environment is long-time down shuts down, and may cause that solution crystallization, cryogen freeze.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of outdoor placed type lithium bromide absorption cold/warm water unit with antifreeze function is provided, can be placed on outdoor, can be at safe and stable operation under the low temperature environment, good looking appearance, floor space is little, noise is low, can save a large amount of machine room construction costs for the user again.
The utility model to achieve these goals, adopted following technical scheme: the outdoor placed type lithium bromide absorption cold/warm water unit of band antifreeze function, comprise that evaporimeter, absorber, condenser, high-temp regenerator, low-temperature regenerator, solution pump, refrigerant pump, cryogen coagulate the unit that the hydro-thermal retracting device constitutes, unit is installed in the framework, cover plate is installed on the framework, is compounded with puigging on the cover plate.
Described puigging adopts acoustical cotton and Sound-proof material composite bed.
Described cover plate seam crossing is installed rainproof.
Described cover plate adopts water-tight corrosion-proof sheet material, as antirust galvanized sheet, color steel etc.
Twine heater strip on described coolant piping and the refrigerant pump, heater strip twines heat insulation foam outward, and the cryogen discharge solenoid valve is installed between evaporimeter and the absorber, and antifreeze switch is installed in the framework, antifreeze switch automatic detection signal input connects controller, and controller drives and connects the cryogen discharge solenoid valve.
Described heater strip is spirally wound on coolant piping and the refrigerant pump, and pitch is 10-100mm, and can not be overlapping between the heater strip and intersect and twine the unsettled placement of length remainder.
The utility model for unit in outdoor placement, except that normal insulation cold insulation, adopt around unit body installation frame and antirust galvanized sheet outer cover and rainproof, and the unit framework structure is designed to rain-proof structure, make unit not only attractive in appearance but also can accomplish rainproofly, windproof, dustproof, reduced greatly simultaneously owing to build the shared land area of machine room.Reduce noise for outdoor placement machine, by adopting the inboard mode of pasting acoustical cotton and Sound-proof material (avoiding ventilating and opening part) of cover plate, noise that motor such as canned motor pump, burner and vibration produce is absorbed by acoustical cotton and Sound-proof material and isolate, thereby reduce the noise of unit, bring the comfortable work of user, studying and living environment.
The utility model also provides and is suitable for unit and places outdoor scheme that can stable operation in winter of cold in addition; by adopting spiral to twine electrical heating wire and heat insulation foam at unit coolant piping, refrigerant pump etc.; and heat insulation foam is wrapped on the electrical heating wire; the mode that electrical heating wire is wrapped fully; avoid heater strip exposed outside; prevent the heater strip electric leakage, guarantee unit and personnel's safety.Simultaneously electrical heating wire can not be overlapping or be intersected, and grows part and can do unsettled processing.Guarantee unit normal operation and not freezing under underload, low ambient temperature, be lower than under the situation of 0 degree, still run well and do not freeze and crystallization as outdoor environment temperature in the winter time.
For antifreeze running, by the automatic testing environment temperature of antifreeze switch, when environment temperature is spent less than 5, send signal automatically, control cold warm water pump and unit and carry out antifreeze running, prevent that the cold warm water of unit system from freezing.
For long-time halting problem under the low temperature environment; the cryogen discharge solenoid valve is set between evaporimeter and absorber; realize diluting fast, fully running; reach and adapt to the long-time purpose of shutting down of low temperature environment; prevent to freeze generation with crystallization; can quicken to dilute operation process during normal operation, reach purpose of energy saving.
