Abstract
The utility model relates to a high efficiency energy-saving apparatus for supplying hot and cold water, and the utility model is the improvement of an original air conditioner set. A refrigerating compressor 20, a secondary heat exchanger 2, a primary heat exchanger 5, a condenser 7, a primary cooler 9, a secondary cooler 12, a drying filter 14, throttling elements 15, an evaporator 17 and a vapor liquid separator 18 are orderly connected by refrigerant lines 16, wherein, the cooling water pipelines 21 and 22 of the condenser 7 are connected with a cooling tower 19, and a speed-regulation circulation pump 23 is installed on the cooling water pipeline 22. The utility model can produce hot water ranging from 50DEG C to 80DEG C, while carrying out air-conditioning refrigeration; furthermore, refrigerating efficiency is raised by 20% to 30%, and the comprehensive energy efficiency ratio COP cold plus +COP heat ranges from 8.0 to 10.0.
Description
The utility model belongs to refrigeration technology field, particularly the combined system of heating and refrigeration.
The mode of existing refrigeration, heat supply water all is single.The air-conditioning unit of being made up of refrigeration compressor, condenser, device for drying and filtering, restricting element, evaporimeter, vapour liquid separator and cooling tower can only freeze to the room, the heat that cold-producing medium discharges in condenser is delivered to cooling tower by water lines and is scattered and disappeared in atmosphere, has wasted big energy.On the other hand, in the place that needs hot water, all adopt fire coal, oil burning boiler or boilers heated electrically basically, its thermal efficiency is extremely low, consumes a large amount of energy, and seriously polluted.
The purpose of this utility model provides a kind ofly can carry out air conditioner refrigerating to the room, can produce the energy-efficient hot and cold water unit of hot water again.
Below, narrate structure of the present utility model with reference to accompanying drawing.
By refrigerant line 16 refrigeration compressor 20, secondary heat exchanger 2, primary heat exchanger 5, condenser 7, primary cooler 9, secondary cooling device 12, device for drying and filtering 14, restricting element 15, evaporimeter 17, vapour liquid separator 18 are connected in turn, link to each other with cooling tower 19 by the cooling water pipeline of water lines 21,22 with condenser 7.
The structure of secondary heat exchanger 2, primary heat exchanger 5, condenser 7, primary cooler 9 and secondary cooling device 12 is all identical with water cooled condenser.Their water inlet pipe is respectively 3,6,22,10 and 13, and outlet pipe is respectively 1,4,21,8 and 11.
Evaporimeter 17 can be water-cooled evaporimeter or air-cooled type evaporimeter.
Restricting element 15 can be an expansion valve.
In order to save electric energy, speed governing circulating pump 23 is installed on water lines 22.It can adjust rotating speed automatically according to the water temperature in the condenser, when water temperature is enough low, and just stall automatically.
The high-temperature high-pressure refrigerant steam that comes out from refrigeration compressor 20 during this equipment operation enters secondary heat exchanger 2, with cold water heat exchange wherein, and then enters primary heat exchanger 5, continues and cold water heat exchange wherein.And then enter water cooled condenser 7, primary cooler 9 and secondary cooling device 12, successively with wherein cooling water heat exchange.Cold-producing medium self cooling simultaneously changes high-pressure liquid into, enters evaporimeter 17 heat absorption vaporizations again through the cold-producing medium that becomes low-pressure low-temperature behind device for drying and filtering 14 and the restricting element 15, makes medium (water or the air) cooling in the evaporimeter 17 simultaneously, realizes air conditioner refrigerating.When the water lines of primary cooler 9, primary heat exchanger 5, secondary heat exchanger 2 is connected mutually, make of water inlet pipe 10 inflows of the cold water of needs heating from primary cooler 9, can obtain 50～80 ℃ hot water at outlet pipe 1 place of secondary heat exchanger 2 so.Primary heat exchanger 5, the water inlet pipe and water outlet pipe of secondary heat exchanger 2 also can use separately, to obtain the hot water of different temperatures.Can enter low temperature (7-12 ℃) cold water from water inlet 13, the cold-producing medium in the secondary cooling device 12 is lowered the temperature, to improve refrigerating efficiency.At primary heat exchanger 5, secondary heat exchanger 2 whole heat exchange heat water, in the time of guaranteeing that restricting element 15 place's refrigerant temperatures are lower than requiring of refrigeration system duty, speed governing circulating pump 23 can not worked, at primary heat exchanger 5, when secondary heat exchanger 2 part heat exchange heated water, speed governing circulating pump 23 can the speed-regulating electricity-saving operation.When having saved former refrigeration unit discharging used heat so again, the electric energy that cooling system equipment is consumed.The utlity model has following advantage: save the energy.As mentioned above, this device can obtain 50 ℃～80 ℃ hot water when carrying out air conditioner refrigerating, unidirectional power consumption, two-way being benefited.Save energy consumption more than 100% than original air-conditioning unit, save energy consumption more than 60% than lithium bromide air-conditioning.In addition, because speed governing circulating pump 23 is installed on the water lines 22 of cooling tower 19, it can be according to the height of the water temperature in the condenser 7, automatic speed regulation, or shut down, so can save a large amount of electric energy.The comprehensive Energy Efficiency Ratio COP of this device is cold+COP heat=8.0～10.0.
This equipment is applicable to the hotel, the hostel, and the condo, swimming pool, enterprises and institutions etc. are not only with central air-conditioning but also need the unit of hot water to use.
