Description

Year round cooling wind-cooled cold-water unit
Technical field
The utility model belongs to the refrigerating machine technical field, relates to a kind of wind-cooled cold-water unit, the wind-cooled cold-water unit of a kind of year round cooling of more specifically saying so.
Background technology
Many big cities, the world today face the problem of shortage of water resources, and the cooling tower of the very big water-cooling air conditioner configuration set of current social installed capacity consumes the not water of small scale, thereby the conserve water a resource shrinkage water waste very urgent thing of air-conditioning industry beyond doubt.Compare the water-cooled refrigeration unit; Air-cooled unit has saved cooling tower, cooling water pump, pipe network and water treatment facilities thereof; Be highly suitable for nervous area, water source, the social demand amount that can predict air-cooled unit will be more and more big, also can be more and more high to the requirement of air cooling chiller group.
The course of work of various air-conditioning systems is exactly an energy handling process in fact: during refrigeration carry away energy, when heating come the energy carrying.Because air-cooled unit utilizes air to come the cooling refrigeration agent, and environment temperature is very big with seasonal variations, and the cooling water temperature of water-cooled unit is much smaller with seasonal variations.Requiring the occasion of year round cooling, seasonal variations is little to the influence of the refrigerating capacity of water-cooled unit, but concerning air-cooled unit, variation of ambient temperature and its refrigerating capacity have direct relation.Though existing wind-cooled cold-water unit comprises compressor, air-cooled condenser, throttling arrangement, evaporimeter, wherein air-cooled condenser is made up of several radiators and condensation fan; But its area of dissipation size does not change during operation; Just rely on operation blower fan number change to change air quantity; The adjustment of this cooling capacity is very limited, can't adapt to the needs of year round cooling operation, thereby cause the waste of the energy and the instability of wind-cooled cold-water unit operation.
Summary of the invention
The technical problem that the utility model will solve and the technical assignment of proposition are to overcome the defective that existing wind-cooled cold-water unit operation is unstable, cause energy waste, and a kind of year round cooling wind-cooled cold-water unit is provided.
For this reason; The year round cooling wind-cooled cold-water unit of the utility model; Comprise the compressor, air-cooled condenser, liquid reservoir, throttling arrangement, the evaporimeter that are connected in the circulating refrigerant loop; Said air-cooled condenser comprises some groups of radiators and the blower fan of being controlled by controller; It is characterized in that: further comprising magnetic valve, pressure sensor, temperature sensor by controller control, described temperature sensor is arranged in the environment of wind-cooled cold-water unit operation, and described pressure sensor is installed on the compressor exhaust pipe; Selectivity disposes described magnetic valve on described each radiator.
As the optimization technique measure, described controller is connected with described blower fan, magnetic valve, temperature sensor, pressure sensor signal respectively.
As the optimization technique measure, described magnetic valve is connected on the exit of corresponding radiator.
The utility model is owing to have independently blower fan and magnetic valve respectively on several radiators; And the motor of blower fan adopts variable-frequency motor; Temperature sensor is set in the environment of wind-cooled cold-water unit operation simultaneously and on gas exhaust piping, is provided with back pressure transducer; During the unit refrigerating operaton; Controller is regulated magnetic valve and blower fan on each radiator outlet pipeline of condenser respectively according to temperature signal and the pressure signal gathered, through unlatching, the adjusting rotation speed of fan of control magnetic valve and blower fan, control condenser heat.Therefore the air-cooled condenser of the wind-cooled cold-water unit of the year round cooling of the utility model can be regulated with variation of ambient temperature, reaches the effect of energy savings, and makes the wind-cooled cold-water unit operation stable.In summer during unit operation, because environment temperature is high, the temperature difference of condenser and environment temperature is less, thereby magnetic valve needs all to open the radiating conditions that the best is provided for unit with blower fan, and the realization unit efficiently moves.When moving in the winter time, because temperature is low, the temperature difference of condenser and environment temperature is bigger; Magnetic valve and blower fan can partly be opened; Through reducing condensing heat-exchange area and air velocity, control the condensation ability and the refrigeration system demand adapts, realize the purpose of year round cooling.
Description of drawings
Fig. 1 is the refrigeration system schematic flow sheet of utility model year round cooling wind-cooled cold-water unit.
Among the figure: 1-compressor, 2-air-cooled condenser, 3-throttling arrangement, 4-evaporimeter, 5-liquid reservoir, 6-device for drying and filtering, 7-magnetic valve, 8-pressure sensor, 9-temperature sensor, 10-blower fan, 11-radiator, 12-controller.
The specific embodiment
Below in conjunction with Figure of description the utility model is further specified.
The year round cooling wind-cooled cold-water unit of the utility model; As shown in Figure 1; It comprises compressor 1, air-cooled condenser 2, throttling arrangement 3, evaporimeter 4, the liquid reservoir 5 that is connected in the circulating refrigerant loop, and wherein air-cooled condenser 2 comprises some groups of radiators 11 and blower fan 10.The wind-cooled cold-water unit of said structure and prior art is similar, therefore no longer launches to describe.
The characteristics of the year round cooling wind-cooled cold-water unit of the utility model are that it also comprises controller 12 and temperature sensor 9 and pressure sensor 8; Temperature sensor 9 is arranged in the environment of wind-cooled cold-water unit operation, and pressure sensor 8 is arranged in the compressor air-discharging outlet.
Each radiator (radiator coil tube) outlet can be installed magnetic valve 7 as required, and controller 12 is connected with the signal of blower fan 10, magnetic valve 7, temperature sensor 9, pressure sensor 8 respectively.Magnetic valve 7 is connected on the exit of radiator coil tube 11.Temperature sensor 9 and pressure sensor 8 are sent to controller 12 with temperature and pressure signal when the wind-cooled cold-water unit operation; Controller 12 is regulated the magnetic valve and the blower fan of air-cooled condenser 2 each radiator coil tube 11 outlet respectively according to the temperature, pressure signal; Through unlatching, the adjusting rotation speed of fan of control magnetic valve and blower fan, control condenser heat.This respect can carry out CONTROLLER DESIGN according to above-mentioned requirements in the control technology field, therefore also not in concrete expansion.
The operation principle of the wind-cooled cold-water unit of the year round cooling of following brief account utility model, compressor 1 sucks the low-temperature low-pressure refrigerant steam of flash-pot 4, becomes the superheated vapor of HTHP after the both vapor compression work done to low-temp low-pressure.Then, the refrigerant vapour of high pressure-temperature gets into air-cooled condenser 2, and through the forced ventilation of blower fan 10, the surrounding air lower with temperature carries out heat exchange, with the heat transferred air that is discharged in the condensation process, makes gaseous refrigerant be condensed into highly pressurised liquid.Highly pressurised liquid becomes the higher gas-fluid two-phase mixture of low-temp low-pressure and content liquid through throttling arrangement 3 after the throttling step-down, these gas-fluid two-phase mixtures get into evaporimeter 4.In evaporimeter 4; The cold-producing medium of low-temp low-pressure will be higher relatively with temperature chilled water generation exchange heat; Refrigerant liquid becomes generating gasification into the low-temperature low-pressure refrigerant steam behind the heat of absorption refrigerating water, thereby the temperature that has reduced chilled water reaches the refrigeration purpose.Refrigerant vapour after the gasification will be inhaled into compressor, so reciprocation cycle.
