The utility model is characterized in that it has an integral-type shell body and all parts of unit are arranged in the interior of shell body; the interior of shell body is provided with the screw-type compressor; the compressor is connected with the evaporator through the cooling medium circulating pipeline; the interior of shell body is provided with a relatively closed evaporative condenser, the bottom of the condenser is filled with a certain amount of water, and the outdoor ventilation orifice of the condenser is provided with the fan; the cooling medium circulating pipeline is connected with the interior of the condenser.
Description
Technical field
The utility model is a kind of novel handpiece Water Chilling Units, adopts evaporative condenser to replace traditional water cooled condenser specifically.
Background technology
The central air-conditioning of being installed in building and commercial sub-district at present adopts following two kinds of schemes usually.
One class is to adopt the organization plan of the supporting cooling tower of water-cooling screw rod machine.Be about to main frame and be installed in the special-purpose machine room, by pipeline cooling water is transported in the cooling tower at a distance and carries out cool cycles.This type of organization plan need be provided with special-purpose machine room in the building inboard, also needs to carry out regular maintenance by the special messenger, and the loss of installation complexity, cooling water is bigger, so the initial investment of entire system is bigger.
Another kind of is the organization plan that adopts the air-cooled screw rod machine of outdoor mounted.Because air-cooled unit condensation temperature is higher, thereby the entire system Energy Efficiency Ratio is lower, operating cost is high, can cause significantly fuel factor to the building surrounding environment.
In addition, the disease that causes about " Legionella " in recent years happens occasionally.According to statistics, the cooling tower of air-conditioning system is its main infection sources.Form a large amount of glutinous mud gradually owing to can gather impurity such as dust in air in the cooling tower of open type.Glutinous mud has just become the place of bacterial reproduction growth.At this moment, when the cooling tower inner blower cooled off cooling water, the water that carries disease germs promptly had been blown to fine water particles.And the people is in case suction will cause infection because of it directly arrives alveolar position.
The utility model content
Monoblock type screw chiller group described in the utility model, its purpose of design is to address the above problem and adopts evaporative condenser to replace traditional water cooled condenser, the air that sucks or be pressed into by cooling blower in condenser is realized the evaporation of water that circulates, the mechanism of utilizing water evaporation to absorb heat reduces the temperature of the inner refrigerant pipeline of condenser, thus finally realize and refrigerant between heat exchange.
For realizing above-mentioned purpose of design, the primary structure of described monoblock type screw chiller group has:
One all-in-one-piece housing, each parts sealing of unit is installed on enclosure interior;
In housing, be provided with screw compressor;
Compressor is connected with evaporimeter by medium circulation pipeline;
The evaporative condenser of one relative closure is set in housing, is filled with a certain amount of water in the condenser bottom, ventilating opening one side is provided with blower fan in the outside of condenser;
Described medium circulation pipeline is communicated to condenser inside.
As above-mentioned organization plan, described monoblock type screw chiller group, when the refrigerant vapor of discharging from compressor is flowed through the pipeline of described evaporative condenser inside, because fan operation and with the water evaporates of condenser inside, water evaporates and draw a large amount of heats in that condenser is inner, thereby the temperature on medium circulation pipeline surface reduces, and refrigerant is sucked away behind the heat and becomes liquid state and flow out condenser.
When refrigerant was flowed through evaporimeter, the refrigerant of low temperature can carry out heat exchange with the indoor air, thereby realized the cooling of indoor circulating air is handled.
For improving the thermal efficiency of total system, adopt the dry type shell and tube evaporator.
Described condenser fan can be installed suction-type blower fan or forced blower fan at outside ventilating opening place.
For reducing the floor space of housing, described compressor is arranged on the top of evaporimeter.
As above content, the advantage of described monoblock type screw chiller group is:
1, in the above-mentioned handpiece Water Chilling Units, adopt screw compressor and evaporative condenser, the refrigerating capacity of whole unit is higher;
2, the condenser that is adopted is an evaporative condenser, is installed in the integral housing relative closure, and system architecture is comparatively simple, only needs during installation chilled water import and export, the condenser water supplement port of evaporimeter are connected with external pipeline system;
3, described handpiece Water Chilling Units regularly replaces part recirculated water and gets final product in running, and unit also can be installed in the open;
4, can overcome the problem that " Legionella " easily grows in the existing air-conditioning system effectively.
5, solved the bigger problem of moisture content windage in the existing cooling water system, economized on water more than 50% than common water cooling unit.
Description of drawings
Fig. 1 is the handpiece Water Chilling Units structural representation of embodiment 1;
Fig. 2 is the handpiece Water Chilling Units structural representation of embodiment 1;
As depicted in figs. 1 and 2, housing 1, screw compressor 2, medium circulation pipeline 3, evaporimeter 4, condenser 5, water 51, suction-type blower fan 52, forced blower fan 53, outside ventilating opening 54.
The specific embodiment
Be provided with screw compressor 2 in housing 1, a dry type shell and tube evaporator 4 is set in the bottom of compressor 2, compressor 2 is connected with evaporimeter 4 by medium circulation pipeline 3.
The evaporative condenser 5 of one relative closure is set in the left side of housing 1, is filled with a certain amount of water 51 in the bottom of condenser 5, one forced blower fan 53 is set in the lower-left of condenser 5 side.
Described medium circulation pipeline 3 is communicated to the inside of condenser 5.
When the work of monoblock type screw chiller group moves, when the refrigerant vapor of discharging from compressor 2 is flowed through the pipeline of condenser 5 inside, because the air that is pressed into after blower fan 53 is opened evaporates water 51 partly, take away the heat of the refrigerant of medium circulation pipeline 3 inside during water 51 evaporations, refrigerant becomes liquid back and flows out condenser 5, thus the operation principle that realization is carried out heat exchange by evaporimeter and indoor air.
As different from Example 1, at outside ventilating opening 54 places on condenser 5 tops one suction-type blower fan 52 is set.
