Abstract
The present invention relates to a city bus ice cold storage air conditioner cold supply device which mainly comprises an ice storage tank, a drain valve, a circulation water pump, a coil heat exchanger, a condensed water drain pipe, an axial flow fan, a circulating pipe, an expansion water tank, a three-way valve and an expanded water pipe. The cold supply device comprises no compressor, and adopts the circulation water pump with low power in order to overcome the defect of flow resistance of coolants in the circulating pipe and the coil heat exchanger. The cold quantity of ice blocks in the ice storage tank is endlessly conveyed into the coil heat exchanger by the coolants (in the circulating pipe) driven by the circulation water pump. Hot air in buses endlessly flows through the shell side of the coil heat exchanger under the action of the axial flow fan, and after the hot air is cooled by the coil heat exchanger, the cold air is sent into the buses to realize the temperature drop on air in the buses. The ice blocks desired by cold supply are supplied by a centralized ice manufacture station, night electric energy with low price is utilized for ice manufacture, the load of bus engines is lightened, the exhaust gas discharge amount is lowered, and the present invention has no condensation heat extraction. The present invention has the advantages of simple structure and obvious social benefits and economic benefits such as environmental protection, low investment, convenient installation, convenient maintenance, etc.
Description
Technical field
What the present invention relates to is a kind of ice-storage air-conditioning cooling apparatus, and particularly a kind of ice-storage air-conditioning cooling apparatus that is used for city bus belongs to air conditioner refrigerating and vehicular equipment field of engineering technology.
Background technology
Along with the raising of people's living standard and the fierceness day by day of market competition, increasing city bus has all been installed aircondition.At present, in existing car air-conditioner refrigerating plant technology, application number is 00239932, and name is called the patent of invention of bus air conditioner machine; Application number is 01212348, and name is called the patent of invention of automobile-used chiller compartment device; Application number is 01276950, and patent of invention and application number that name is called Refrigerating for passenger train equipment are 02230007, and name is called a kind of patent of invention of Refrigerating for passenger train equipment etc., all directly or indirectly drives compressor by vehicular engine and freezes.This not only increases burden, increase air-conditioned coach oil consumption and the exhaust gas discharging amount of engine, but also causes the thermal pollution that is caused by the condensation heat extraction of air-conditioning unit.Simultaneously, existing car air-conditioner refrigerating plant is because complex structure such or such defect occurs through regular meeting, and this has brought a lot of troubles to maintenance.
Summary of the invention
In order to overcome the shortcomings and deficiencies of prior art, satisfy the needs of China's city bus aircondition development, the present invention designs a kind of car air-conditioner cooling apparatus that does not need compressor, i.e. ice-storage air-conditioning cooling apparatus.Ice storage technology utilizes the low power consumption phase at night to carry out the electricity refrigeration, and the cold that makes is stored for air-conditioning use on daytime with the form of icing.Ice storage technology not only helps distributing rationally of urban energy, and the electric power of urban distribution network is played the effect of peak load shifting, but also owing to the difference of time-of-use tariffs declines to a great extent the operation of air conditioner expense.
The present invention mainly comprises Ice Storage Tank, water circulating pump, coil heat exchanger, axial flow blower, circulating water pipe, expansion tank and expansion water pipe etc.When water circulating pump is opened, the cold of ice cube just is delivered in the coil heat exchanger by the refrigerating medium in the circulating water pipe (mixture of water and antifreezing agent) in the Ice Storage Tank, then that bus is the indoor hot-air of axial flow blower is introduced in the coil heat exchanger, by with the coil heat exchanger heat exchange after be blown in the car, thereby realize the cooling of air in the car.
This air-conditioning cooling apparatus does not have compressor, adopt low power water circulating pump, to overcome the flow resistance of refrigerating medium in circulating water pipe and coil heat exchanger, the required ice cube of its cooling is provided by concentrated ice making station, so do not need to consume a large amount of gasoline of bus or diesel oil comes for the air-conditioning service is provided in the car, not only alleviated the load of bus engine, reduced the exhaust emissions amount of bus, but also the condensation heat extraction of having stopped present car air-conditioner, thereby significantly reduced the influence of air-conditioner vehicle to urban environment.Concentrate the ice making station can utilize the electric energy of cheapness at night to carry out ice making, will reduce the cost of ice making greatly, can not cause burden simultaneously the electrical network in city.At present, Cheng Shu ice storage technology is laid a good foundation for the feasibility of patent of the present invention.This device has environmental protection, invests remarkable social benefit and economic benefits such as low, convenient for installation and maintenance.
