Description
Technical field
But the utility model relates to the energy savings device in air conditioner refrigerating field, especially a kind of air-conditioning system that is mainly used in people's productive life environment can be produced a kind of handpiece Water Chilling Units heat recovery system that has cool storage function of domestic hot-water when producing cold.
Background technology
The relative shortage of the energy more and more becomes the bottleneck of the economic sustainable and healthy development of restriction China, this contradiction in quite long from now on period with long-term existence, and further significantly trend is arranged, simultaneously, rapid development of economy also is at the cost of the environment, and nowadays people's environment of depending on for existence can't bear the heavy load.For this reason, country has established the energy policy of " save with exploitation and lay equal stress on, save preferential ", and proposes the brand-new idea of development of " Scientific Outlook on Development ", " building a harmonious socialist society ".The improvement day by day with working condition of improving constantly along with living standard, people have also proposed strict more requirement to the productive life environment, the application of air-conditioning is also more and more universal, and all kinds of handpiece Water Chilling Units have become important implementation, but what follow is huge energy resource consumption.Therefore, reduce the energy resource consumption of air-conditioning, seek the road of air-conditioning sustainable development, an important and primary problem that has become Air-conditioner design and faced.
The refrigeration duty of air-conditioned room enters the cold-producing medium circulation by evaporimeter, becomes the condensation heat extraction with consumption of compressor, is discharged in the atmosphere by the cooling water circulation and goes.Therefore, for the conventional air-conditioning refrigeration machine, it mainly acts on is air conditioning, and the condensation heat of air-conditioning system directly is discharged in the atmosphere and is not used.To a large amount of condensation heat of atmospheric environment discharging, common condensation heat can reach 1.15～1.3 times of refrigerating capacity when refrigeration unit was moved under air conditioning condition.A large amount of condensation heat directly enters atmosphere, loses in vain, causes bigger energy waste, and distributing and ambient temperature being raise of these heats causes the serious environmental thermal pollution.If the condensation heat that refrigeration machine is emitted is reclaimed, be used for heating domestic hot-water and production technology hot water, not only can reduce the condensation heat pollution on the environment, but also be a kind of power-economizing method of turning waste into wealth.
The cold-storage technology, be with air conditioning electricity from daytime the peak period transfer to the night dip phase, balanced urban distribution network load, reach the purpose of many peak loads, the principle of cold-storage technology, in brief, be to utilize remain in operation refrigeration machine refrigeration of the unnecessary charged power of paddy of electrical network at night, and store with the form of ice, provide the air-conditioning service with ice-out during peak of power consumption by day, thereby avoid central air-conditioning contention peak power.
The handpiece Water Chilling Units heat recovery system is produced the domestic hot-water, and night, hot water demand's amount was bigger, and this moment, the air-conditioning demand reduced, and the produced simultaneously cold that the handpiece Water Chilling Units heat recovery system is produced the domestic hot-water consumes nowhere, causes problems such as waste.
Summary of the invention
In order to overcome above-mentioned weak point, main purpose of the present utility model aims to provide a kind of on the basis of handpiece Water Chilling Units heat recovery system commonly used, increase a suit of cold-storage system, adopt handpiece Water Chilling Units recuperation of heat and cold-storage device hybrid system, the application technology that combines with the handpiece Water Chilling Units heat recovery system by cold accumulation system, when produce the domestic hot-water night, the cold that produces is stored, wait until again cold to be discharged daytime, enable the handpiece Water Chilling Units heat recovery system that has cool storage function of effective energy savings.
The technical problems to be solved in the utility model is: mainly solve the application technology problem that cold accumulation system combines with the handpiece Water Chilling Units heat recovery system that how to design; Solve the condensation heat of how refrigeration machine being emitted and reclaimed, be used for heating domestic hot-water and production technology hot water problem; How to solve from abundant handpiece Water Chilling Units condensation heat, consider the big and relevant technologies problems such as contradiction that refrigeration requirement is little and energy-conservation needs of hot water demand at night.
The technical scheme that its technical problem that solves the utility model adopts is: on the basis of the original handpiece Water Chilling Units heat recovery system of using always, increase a suit of cold-storage system, this system comprises: parts such as evaporimeter, valve and handpiece Water Chilling Units, on the structure of handpiece Water Chilling Units heat recovery system, set up a suit of cold-storage device, above-mentioned each parts are combined as holistic handpiece Water Chilling Units heat recovery system, and this system includes at least:
One side of a suit of cold-storage device interconnects by valve A, valve B and valve C and associated pipe successively, and another road of valve A and valve B tie point interconnects by an end of associated pipe and evaporimeter; The opposite side of cold-storage device interconnects by valve D, valve E and valve F and associated pipe successively, and another road of valve E and valve F tie point interconnects by the other end of associated pipe and evaporimeter;
The associated pipe of leading up to of one evaporimeter interconnects with compressor, condenser and expansion valve successively, and another road and the chilled water pipeline of evaporimeter interconnect;
The associated pipe of leading up to of one condenser interconnects with expansion valve, evaporimeter and compressor successively, and another road and domestic hot-water's pipeline of condenser interconnect.
The beneficial effects of the utility model are: the application technology that this handpiece Water Chilling Units heat recovery system combines with the handpiece Water Chilling Units heat recovery system by cold accumulation system, the condensation heat that refrigeration machine can be emitted is reclaimed, be used for heating domestic hot-water and production technology hot water, when produce the domestic hot-water night, the cold that produces is stored, wait until that discharge cold daytime again, not only can reduce the condensation heat pollution on the environment, but also be a kind of handpiece Water Chilling Units heat recovery system of the effective energy savings that turns waste into wealth.
