Abstract
The utility model relates to a heat recovering type water cooling cold water unit, which belongs to the technical field of a refrigeration facility. The utility model comprises a compressor (1), a condenser (4), an evaporator (9), refrigeration accessories, a connecting pipeline, etc. The utility model is characterized in that a high temperature hot water heat exchanger (2) is added at the front of the condenser (4), a group of low-temperature hot water heat exchange tube bundles (5) are additionally arranged in a cavity body of the condenser (4) simultaneously, and an outlet of the low-temperature hot water heat exchange tube bundles (5) is connected with a hot water inlet of the high temperature hot water heat exchanger (2). The utility model not only can provide high temperature life hot water, but also can reduce the input power of the compressor effectively to guarantee that the compressor can run safely for a long time.
Description
Technical field:
The utility model relates to a kind of water-cooled handpiece Water Chilling Units, especially relates to a kind of band heat reclamation type water-cooled handpiece Water Chilling Units.Belong to technical field of refrigeration equipment.
Background technology
Before the present invention makes, conventional water-cooled handpiece Water Chilling Units is formed a refrigeration cycle by compressor, condenser, evaporimeter, refrigeration annex and connecting line etc., this unit can only provide idle call cold water in summer, and (12 ℃ are advanced, 7 ℃ go out), its heat of discharging then adopts cooling water (30 ℃ are advanced, and 35 ℃ go out) by cooling tower heat to be entered atmosphere.Understand according to our market survey, hotel's lodging industry for energy savings better, reduce operating cost, wish that all this unit can also gratis provide a large amount of 45-50 ℃ domestic hot-water to come the bathing for the guest in refrigeration.For this reason, the producer that had in the past also once produced the handpiece Water Chilling Units of band recuperation of heat, but it has just increased a common hot water heat exchanger before condenser.Because this structure has also increased high temperature refrigerant gas flow resistance greatly when hot water is provided, thereby has also shortened the service life of compressor in the input power that has improved compressor greatly.That have even caused burning of compressor.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of thermobiosis hot water can be provided, again more effectively the input power of compresses machine to guarantee the band heat reclamation type water-cooled handpiece Water Chilling Units of compression function long-term safety reliable operation.
The purpose of this utility model is achieved in that a kind of band heat reclamation type water-cooled handpiece Water Chilling Units, it comprises compressor, high-temperature-hot-water heat exchanger, condenser, evaporimeter, refrigeration annex and connecting line etc., be characterized in high-temperature-hot-water heat exchanger of addition before condenser, in the condenser cavity, set up simultaneously one group of low-temperature water heating heat-exchanging tube bundle again, this low-temperature water heating heat-exchanging tube bundle import is made a living and is applied flexibly water inlet, and its outlet links to each other with the hot water inlet of high-temperature-hot-water heat exchanger.
Heat reclamation device of the present utility model is made up of two parts heat exchange: first is arranged at the outer high-temperature-hot-water heat exchanger of condenser, it is the heat that utilizes the high-temperature gas of compressor discharge, make the outlet temperature of heat exchanger hot water rise to 45～50 ℃, with the requirement of the domestic water that satisfies people; Second portion is the low-temperature water heating heat-exchanging tube bundle that is arranged in the condenser cavity, is that profit presses the condensation heat of the low-grade Freon gas in the condenser to improve the hot water inlet temperature of high-temperature-hot-water heat exchanger.Because this heat exchanging part can not increase the exhaust resistance of compressor, thereby the input power of compressor is significantly reduced on year-on-year basis, thereby makes that the operation of compressor is reliable more economically yet.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a high-temperature-hot-water heat exchanger structure schematic diagram of the present utility model.
The specific embodiment:
Referring to Fig. 1, the utility model is a kind of band heat reclamation type water-cooled handpiece Water Chilling Units, mainly is made of the refrigeration cycle of a complete band recuperation of heat compressor 1, high-temperature-hot-water heat exchanger 2, by-passing valve 3, condenser 4, low-temperature water heating heat-exchanging tube bundle 5, magnetic valve 6, expansion valve 7, evaporimeter 8, refrigeration annex and connecting line etc.Wherein high-temperature-hot-water heat exchanger 2 is arranged on the pipeline before the condenser 4, and low-temperature water heating heat-exchanging tube bundle 5 is arranged in condenser 4 cavitys, and these low-temperature water heating heat-exchanging tube bundle 5 outlets link to each other with the hot water inlet of high-temperature-hot-water heat exchanger 2.
The utility model also can be on the connecting pipeline of compressor 1 and condenser 4 and high-temperature-hot-water heat exchanger 2 by-passing valve 3 that is connected in parallel.In the time need not providing high-temperature-hot-water, open this by-passing valve and can further reduce the exhaust resistance of compressor, thereby reduce the input power of compressor, so both reduced operating cost, prolonged the service life of compressor again greatly.
Referring to Fig. 2, high-temperature-hot-water heat exchanger 2 has two or more, and the housing of two or more high-temperature-hot-water heat exchangers 2 is arranged side by side and flow process is connected in series.It is more reasonable with the arrangement length that reduces heat exchanger the complete machine external form to be arranged.Structure is compact more.
Claims (3)
1, a kind of band heat reclamation type water-cooled handpiece Water Chilling Units comprises compressor (1), condenser (4), evaporimeter (9), refrigeration annex and connecting line.It is characterized in that at condenser (a 4) high-temperature-hot-water heat exchanger of preceding addition (2), simultaneously set up one group of low-temperature water heating heat-exchanging tube bundle (5) again in condenser (4) cavity, this low-temperature water heating heat-exchanging tube bundle (5) outlet links to each other with the hot water inlet of high-temperature-hot-water heat exchanger (2).
2, a kind of band heat reclamation type water-cooled handpiece Water Chilling Units according to claim 1, it is two or more to it is characterized in that high-temperature-hot-water heat exchanger (2) has, and the housing of two or more high-temperature-hot-water heat exchangers (2) is arranged side by side and flow process is connected in series.
