Description of drawings
Fig. 1 system of the present utility model constitutes schematic diagram.
The specific embodiment
The utility model provides a kind of pair of cycle industrial handpiece Water Chilling Units, in the general industry handpiece Water Chilling Units, increase water tank and inside and outside water circulating pump, chilled water is introduced into water tank, by interior water circulating pump the water in the water tank is sent into evaporimeter again, chilled water in evaporimeter with the cold-producing medium heat exchange, the water that becomes low temperature is got back in the water tank, sends to client by the outer circulation water pump again.Discharge pressure behind this unit can satisfy the requirement of people to higher discharge pressure, and this handpiece Water Chilling Units compactness rational in infrastructure, and maintenance is convenient.It will be appreciated by those skilled in the art that below in conjunction with accompanying drawing for convenience and further specify.
As shown in Figure 1, compressor outlet is connected with condenser inlet, and condensator outlet is connected with evaporator through expansion valve 1, and evaporator outlet is connected with compressor inlet.Chilled water outer circulation water inlet inserts water tank, and the outer circulation delivery port of water tank connects outer circulation water pump 3, and the interior circulating outlet of water tank inserts the water inlet of evaporimeter behind interior water circulating pump 2, loop back the mouth of a river in the water tank and be connected with the delivery port of evaporimeter.
The high-temperature high-pressure refrigerant steam that compressor is discharged, enter condenser, carry out heat exchange, the refrigerant liquid of warm high pressure in being condensed into cooling water, enter expansion valve 1 again, the throttling step-down is the refrigerant liquid of low-temp low-pressure, enters evaporimeter then, the heat of absorption refrigerating water, become the refrigerant gas of low-temp low-pressure, get back to compressor, form a refrigerant loop, and so circulation.
The water route of unit connects as follows: chilled water is introduced into water tank, send into evaporimeter by interior water circulating pump 2 again, carry out heat exchange with the refrigerant liquid of low-temp low-pressure, the chilled water that becomes low temperature is got back to water tank, become the chilled water of high pressure then through outer circulation water pump 3, send to user side.When interior circulated refrigerated water leaving water temperature reached setting value, unit promptly unloaded shutdown.
