Abstract
The utility model provides an improved freeze protection central air-conditioning water chiller which comprises an evaporator. The evaporator is provided with a temperature probe, a water inlet pipe orifice, a water outlet pipe orifice, a coolant inlet pipe orifice and a coolant outlet pipe orifice. The improved freeze protection central air-conditioning water chiller is characterized in that the temperature probe is mounted on a pipe cavity side of the coolant outlet pipe orifice of the evaporator. By the aid of the structure, complete freeze protection can be realized by detecting the temperature of coolants to control freeze protection, damage of the evaporator and other components are effectively prevented, and the service life of the water chiller is prolonged.
Description
Technical field
This reality is novel to relate to a kind of central air-conditioning cooling-water machine, particularly utilizes the fluorine circulating water unit water route anti-frost protection of air-conditioning, reaches a kind of central air-conditioning cooling-water machine of improveing anti-frost protection that guarantees that unit is not damaged by frost and damages.
Background technology
Central air-conditioning handpiece Water Chilling Units and central air-conditioning generally all are that employing water is that medium carries out heat exchange, the phenomenon that the freezing main frame heat exchanger of water freezing in refrigeration, occurs easily, general discharge is not enough, water line block or water pump failure and other reasons all may cause this phenomenon, the freezing consequence of main frame evaporimeter is very serious, because water penetrates into system the most accessory in the main frame is damaged, particularly compressor.The temperature detecting point of the general antifreeze control of central air-conditioning cooling-water machine all is mounted on the intake-outlet of main frame, because the heat transfer of water is slower, particularly in the immobilising situation of water, is difficult to play antifreeze purpose like this.
The destruction of a total refrigeration system.The workload of maintenance is large, and cost is high.Very important so handpiece Water Chilling Units is antifreeze.
Summary of the invention
In order to guarantee that the air-conditioning unit is not damaged by frost; improve the utilization rate of product; the utility model provides a kind of central air-conditioning cooling-water machine of improveing anti-frost protection; body is made of evaporimeter; described evaporimeter is provided with temp probe; be provided with the water turnover mouth of pipe, be provided with the refrigerant turnover mouth of pipe, it is characterized in that: described temp probe is installed in the tube chamber side of the refrigerant outlet spout of above-mentioned evaporimeter.
After adopting said structure, the pipe of refrigerant outlet spout is little, and detecting temperature is more accurate, rapid than the water route.Refrigerant is given temp probe thermotonus by the heat conduction of copper pipe, reacts very fast.And the temperature of water is certainly higher than the temperature of refrigerant, is to reach 100% anti-frost protection, is damaged by frost to reach the device that effectively avoids evaporating, prevent the damage of other parts so adopt the temperature that detects refrigerant to control antifreeze, prolongs the useful life of product.
Description of drawings
Fig. 1 is evaporation structure schematic diagram of the present utility model.
Be denoted as among the figure: 1 evaporimeter, 11 water inlet pipe mouths, 12 effluent pipe mouths, 13 refrigerant inlet pipe mouths, 14 refrigerant outlet spouts, 15 temp probes.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model title is described in further detail, but does not consist of any restriction of the present utility model.
As shown in Figure 1:
A kind of central air-conditioning cooling-water machine of improveing anti-frost protection; body is made of evaporimeter 1; described evaporimeter 1 is provided with temp probe 15; be provided with water inlet pipe mouth 11, outlet spout 12; be provided with refrigerant inlet pipe mouth 13, the refrigerant turnover mouth of pipe 14, it is characterized in that: described temp probe 15 is installed in the tube chamber side of the refrigerant outlet spout 14 of above-mentioned evaporimeter 1.
After adopting said structure, the pipe of refrigerant outlet spout 14 is little, and detecting temperature is more accurate, rapid than the water route.The heat conduction of refrigerant by copper pipe to temp probe 15, is reacted thermotonus very fast.And the temperature of water is certainly higher than the temperature of refrigerant, is to reach 100% anti-frost protection, is damaged by frost to reach the device that effectively avoids evaporating so adopt the temperature that detects refrigerant to control antifreeze.
Said structure is simple and practical, and can effectively avoid evaporating device and other parts are damaged by frost, and have greatly prolonged the useful life of product.
