Description
Technical field
The present invention relates to a kind of energy-saving equipment, specifically relate to a kind of waste heat that utilizes refrigeration unit to produce and prepare the equipment that hot water uses for the user.
Background technology
Along with the national economy high speed development; the large-scale tall buildings of various styles comprises finance, commerce, office room etc., all needs air-conditioning to keep good working environment in the summer in the south and the north; large-scale central air-conditioning unit is when refrigeration; the unit temperature raises, for protection central air-conditioning unit operate as normal, usually with the capable water cooling of recirculated water; cooling water is through cooling tower; heat is discharged in the outdoor air, thereby causes the waste of energy, also can pollute environment.
Summary of the invention
Purpose of the present invention is to use the residual heat using device of energy savings for the user for the waste heat that makes full use of refrigeration unit generation when freezing prepares hot water.
The technical scheme that adopts is:
The cold unit UTILIZATION OF VESIDUAL HEAT IN of nonstick system of control energy saver comprises refrigeration system, preparation hot-water heating system and control computer.
Refrigeration system is a known technology, and it comprises screw type refrigerating compressor, condenser, evaporimeter, cooling tower.
The preparation hot-water heating system comprises refrigeration working medium and aqueous medium heat exchanger, low-temperature hydrothermal interchanger, high-order storage tank and is arranged on the interior liquid level gauge of high-order storage tank.
Refrigeration working medium exports with water at low temperature with the hot water inlet of high-order storage tank by the road respectively with water inlet with the delivery port of aqueous medium heat exchanger and is connected.And on pipeline, install pump.The condenser hot water output port is connected with the cooling tower shower by the road with the low-temperature water heating outlet of low-temperature hydrothermal interchanger by the road, and the delivery port of cooling column is connected with the condenser water inlet.
The present invention can make full use of the waste heat that the central air-conditioning refrigeration unit produced in when refrigeration, and preparation hot water uses for the user, energy savings not only, and help environment comprehensive system and manage.
Description of drawings
Fig. 1 is a fundamental diagram of the present invention.
The specific embodiment
The cold unit UTILIZATION OF VESIDUAL HEAT IN of nonstick system of control energy saver comprises control computer 1, refrigeration system and hot water preparation system.
Refrigeration system comprises screw type refrigerating compressor 2, condenser 3, evaporimeter 4 and cooling tower 5, and this system is a known technology, so not carefully narration.
The hot water preparation system comprises heat exchanger 6, heat exchanger 7, high-order storage tank 8.Heat exchanger 6 is refrigeration working medium and cooling water heat exchanger.Refrigeration working medium outlet 9 enters the mouth with refrigeration unit compressor cooling working medium and to be connected by the road.The hot water outlet of heat exchanger 6 10 is connected with the hot water inlet of high-order storage tank 8 by the road, is provided with water pump 11 and temperature sensor 18 on pipeline 10, and the water inlet of heat exchanger 6 14 is connected with the delivery port of elevated tank 8 by the road.Be equiped with liquid level gauge 12 by designing requirement on the elevated tank upper inside wall.
Cooling water inlet pipe 13 is connected with pipeline 14 through heat exchanger 7.Cooling water is the 4-6Mpa running water.On pipeline 13, be provided with filter 15, pump 21, magnetic valve 16, pressure sensor 17.The heat supply water out of elevated tank 8 19 is connected with a plurality of users by the road, and overfall is arranged at high-order storage tank 8 tops, and 20 is connected with the shower of cooling tower 5 by the road, and pipeline 20 is provided with magnetic valve 22.
The signal output part of temperature sensor 18, pressure sensor 17, liquid level gauge 12 is connected with the respective signal input of control computer 1.
Operation principle:
When refrigeration unit was worked, the refrigeration working mediums in the heat exchanger 6 were the condition of high temperature, and self temperature improves in the time of the water quench refrigeration working medium, became the hot water that can use for the user, 9 enter high-order storage tank and stored by the road, can be for a plurality of users' uses.Water delay temperature decline in time in storage tank, and, form circulation as in the cooling water Returning heat-exchanger 6.When user's water reaches the moisturizing of setting value need, the liquid level gauge that is located in the storage tank is passed to computer with signal, computer sends instruction and throws magnetic valve 16 on the water pipe 13 into, and can open size according to moisturizing needs control magnetic valve, water pipe 13 becomes low-temperature water heating and enters heat exchanger 6 behind heat exchanger 7.
When user's water consumption little, and when satisfying cooling refrigeration working medium needs again and carrying out moisturizing, the flowmeter 23 that is located on the supply channel 19 reaches computer with signal, when water level rises to overfall in the storage tank, send command signal and open magnetic valve 22 on the pipeline 20, overflow water and 20 enter cooling tower by the road.
The present invention can make full use of the waste heat of refrigeration unit, and helps enhancement of environment.
