Abstract
The utility model relates to high-efficiency energy-saving cold and hot water equipment, which is the improvement of the original air conditioning unit. Heat exchangers 3, 6, 12 and a cooler 15 are connected in series between a refrigerant compressor 1 and a dry filter 17 through a refrigerant pipeline 19, a refrigerant pipeline outlet of a condenser 9 is connected with a refrigerant inlet of the cooler 15, a refrigerant inlet of the condenser 9 is connected to an A or a B or a C point. A valve 21 and a circulating pump 22 are connected between the inlet and the outlet pipes of the heat exchanger 3. The utility model can generate hot water at 50-80 deg C when the air conditioner refrigerates simultaneously. The comprehensive energy efficiency ratio CoP cold + CoP heat is equal to 8.0-10.0.
Description
The utility model belongs to refrigeration technology field, particularly the composite set 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 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, adopt fire coal, oil burning boiler or boilers heated electrically usually, its thermal efficiency is low, consumes a large amount of energy, and seriously polluted.
The purpose of this utility model is that design a kind ofly can be carried out air conditioner refrigerating to the room, can produce the energy-efficient hot and cold water equipment of hot water again.
Below, narrate structure of the present utility model with reference to accompanying drawing.
By refrigerant line 19 refrigeration compressor 1, heat exchanger 3,6,12 and cooler 15, device for drying and filtering 17, restricting element 18 and evaporimeter 20 are connected in turn, constitute closed circuit.The refrigerant inlet of the refrigerant outlet of condenser 9 and cooler 15 joins, and the refrigerant inlet of condenser 9 is received a or b or c point.A, b, 3 of c are respectively the refrigerant inlets of heat exchanger 3,6,12.
The structure of heat exchanger 3,6,12 and cooler 15 is identical with water cooled condenser, and its water inlet pipe is respectively 4,7,13 and 16, and outlet pipe is respectively 2,5,11 and 14.
Evaporimeter 20 can be water-cooled evaporimeter or air-cooled type evaporimeter.
Condenser 9 can be a water cooled condenser, and its water inlet pipe is 10, outlet pipe is 8, and they can link to each other with cooling tower.
Restricting element 18 can be an expansion valve.
For water temperature that heat exchanger 3 is flowed out is higher, a threeway can be installed on outlet pipe 2, between outlet pipe 2 and water inlet pipe 4, be connected valve 21 and circulating pump 22 then.
During this equipment operation, the high-temperature high-pressure refrigerant steam that comes out from refrigeration compressor 1 enters heat exchanger 3,6,12, cooler 15 and condenser 9, with cooling water heat exchange wherein, make outlet pipe 2,5,11 and 14 flow out hot water, cold-producing medium cooling simultaneously changes high-pressure liquid into, through becoming the cold-producing medium of low-pressure low-temperature behind device for drying and filtering 17 and the restricting element 18, enter evaporimeter 20 endothermic gasifications again, make medium (water or the air) cooling in the evaporimeter 20 simultaneously, realize air conditioner refrigerating.When the water lines of heat exchanger 3,6,12 was connected mutually, cooling water can obtain 50～80 ℃ hot water at outlet pipe 2 places of heat exchanger 3 so from water inlet pipe 13 inflow heat exchangers 12.Heat exchanger 3,6 and 12 water inlet pipe and water outlet pipe also can be independent separately, to obtain the hot water of different temperatures.Can enter low temperature (7～12 ℃) cold water from water inlet pipe 16, to the cooling of the cold-producing medium in the cooler 15, to improve refrigerating efficiency.The high-temperature high-pressure refrigerant that refrigeration compressor 1 is discharged is when flowing through the heat exchanger of condenser 9 and parallel connection with it, always easily from lower the leading up to of temperature.Heat water at heat exchanger 3,6 and 12 whole heat exchange, in the time of guaranteeing that restricting element 17 place's refrigerant temperatures are lower than requiring of refrigeration system duty, cold-producing medium is not hardly by condenser 9 (condenser 9 is worked).When heat exchanger 3,6 and 12 part heat exchange heated water, cold-producing medium was discharged a large amount of heat energy, reduced the pressure of condenser system, the shaft power of compressor was reduced, whole system economize on electricity 10～30%.Like this, in the time of can saving former refrigeration unit discharging used heat, the electric energy that condenser system consumed.
The utlity model has following advantage: save the energy.This device can obtain 50～80 ℃ hot water when carrying out air conditioner refrigerating, unidirectional power consumption, two-way being benefited.Save energy consumption 100% than former air-conditioning unit, save energy consumption more than 60% than lithium bromide air-conditioning unit.The Energy Efficiency Ratio height, the comprehensive Energy Efficiency Ratio CoP of this device is cold+CoP heat=8.0～10.0.
This equipment is suitable in the hotel, hotel, hostel, condo, swimming pool, enterprises and institutions etc. are not only with central air-conditioning but also need the place of hot water to use.
