Description

Circulation ice-melt type ice source heat pump system
Technical Field
The utility model relates to a heat pump air conditioner field especially relates to a circulation ice-melt type ice source heat pump system.
Background
A heat pump is a device that transfers heat from a low temperature environment to a high temperature environment according to the principle of refrigeration. Every time the heat pump consumes 1 part of electric power (or other forms of energy), more than 3-4 parts of heat can be obtained, and the heat pump is a high-efficiency heat supply technical scheme. For water source heat pumps and ground source heat pumps which are widely applied, the basic principle is that heat is directly or indirectly extracted from surface water (water in rivers, lakes and seas) or underground water sources, and after the temperature grade is improved through the refrigeration cycle of a heat pump main machine, heat energy meeting the requirements of heat users is prepared, and the requirements of heating supply, domestic hot water and the like are met. Because the freezing point of water is 0 ℃, when the temperature of a water source after heat is extracted by the water and ground source heat pump devices is lower than 4 ℃, the risk of freezing the heat pump evaporator exists, the existing water and ground source heat pump units do not allow the temperature of a water outlet of the evaporator to be reduced to below 4 ℃ for operation, the temperature of a water inlet of the water source cannot be lower than 9 ℃ according to the calculation of a designed heat exchange temperature difference of 5 ℃, and the operation conditions of the water and ground source heat pump units are severely limited. In the Yangtze river basin of China, the climate of near freezing point with the surface water below 9 ℃ or even close to 0 ℃ in winter is a common climate phenomenon, particularly in the yellow river basin and the northern area, and the living areas of people in similar climate conditions in the world are also comparatively good. Although heat is extracted from underground water for a ground source heat pump, when cold and heat demands in winter and summer are greatly different, the temperature of underground water is gradually reduced along with the accumulation of the operation years of the heat pump, so-called cold accumulation occurs, and finally the temperature of an underground water source is lower than 9 ℃, so that the heat pump unit cannot be normally operated. The areas of North China, northwest China and northeast China all belong to areas with heat load far larger than cold load in summer, so that the phenomenon of cold accumulation of underground water is very common.
In conclusion, the water source heat pump is limited by the climate condition of near freezing point, and the ground source heat pump is limited by the phenomenon of cold accumulation, so that the heat pump system cannot normally operate when the heat demand is the most vigorous in winter, and temporary replacement means with higher energy consumption, such as electric heating, has to be adopted to make up the deficiency of the heat supply capacity, thereby not only increasing the energy consumption, but also improving the equipment and comprehensive construction investment of the heat supply system.

The utility model discloses a circulation ice-melt type ice source heat pump system can divide into two kinds of modes operation of winter heat supply and summer cooling. The specific working principle is as follows:
(1) winter heating mode
Valve 11 is open and valves 12 and 13 are closed. The condenser 1a, the valve 11, the heat supply user end 3 and the hot water pump 9 of the heat pump host 1 are sequentially connected through pipelines to form hot water circulation, and the cooling tower 4 is shielded and does not participate in operation. The low-temperature hot water is sent to the condenser 1a of the heat pump host 1 through the water pump 9, after being heated to the high-temperature hot water (for example, 40 ℃ or more than 45 ℃) meeting the heat supply target temperature, the high-temperature hot water flows into the heat supply user side 3, the heat supply user side 3 is a fan coil, a radiator or other heat exchangers, the high-temperature hot water transfers heat to the heat supply user side such as indoor air or domestic hot water, the temperature is reduced to be low-temperature hot water (for example, 30 ℃ or 35 ℃), and then the low-temperature hot water is sent to the condenser 1a of the heat pump host 1 through the hot water pump.
The evaporator 1b of the heat pump main unit 1, the ethylene glycol pump 8 and the dynamic ice slurry unit 2 are connected in sequence to form an ethylene glycol cycle, and because the working temperature of the cycle is possibly lower than 0 ℃, the circulating medium adopts an ethylene glycol aqueous solution with a lower freezing point temperature and a mass concentration of 20%. The glycol water solution is cooled to-3 ℃ in the evaporator 1b of the heat pump main machine 1 (the standard parameter value of the dynamic ice slurry machine set disclosed in the Chinese patent CN 201520443800.0), then is sent into the dynamic ice slurry machine set 2 under the drive of the glycol pump 8, the temperature is raised to-1 ℃ after heat exchange with water in an ice making cycle in the dynamic ice slurry machine set 2, then the glycol water solution returns to the evaporator 1b through a pipeline, and is cooled to-3 ℃ in the evaporator 1b, and the circulation is repeated, so that the purpose of continuously obtaining heat from the dynamic ice slurry machine set 2 is achieved by the evaporator 1b of the heat pump main machine 1.
Valves 15 and 18 are open and valves 14, 16, 17 and 19 are closed. An ice-making cycle is formed by sequentially connecting an ice water storage tank 6, a valve 18, a cold water pump 10, a dynamic ice slurry unit 2 and a valve 15, and a cold supply user end 5 is shielded and does not participate in operation. The ice water storage tank 6 is a water tank with a heat preservation function, and even if the outside air temperature is lower than 0 ℃, the stored common clear water without any chemical solute is not frozen. Liquid water is extracted from the lower part of the ice water storage tank 6 through a cold water pump 10 and is sent to the dynamic ice slurry unit 2, the liquid water is cooled into fluidized ice slurry at 0 ℃ by the ethylene glycol aqueous solution at-3 ℃ in the ethylene glycol circulation, and the ice slurry flows back to the ice water storage tank 6 from the upper part through a pipeline. Because of the density difference between ice and water, ice water is naturally layered in the ice water storage tank 6, granular ice sand floats on the upper part, and water sinks to the lower part. The water at the lower part of the ice water storage tank 6 is pumped into the dynamic ice slurry unit 2 to prepare ice slurry through continuous circulation, so that the heat pump main unit 1 can continuously and stably realize heat supply operation.
The above is the complete heat pump heating operation mode. Along with the operation of heat supply, the ice in ice water hold up tank 6 will be more and more, and water is less and less, consequently the utility model discloses a one set of solar energy collection circulation melts the ice in ice water hold up tank 6 for liquid to it is enough to maintain the required liquid water yield of ice source heat pump heat supply operation to exist throughout in the assurance ice water hold up tank 6. The ice water storage tank 6, the solar circulating pump 23, the valve 21 and the solar heat collector 7 are sequentially communicated to form a solar heat collecting circulation, and the valve 21 is normally opened. Under the condition of solar illumination energy in the daytime, liquid water at the lower part of the ice water storage tank 6 is pumped out through the solar circulating pump 23 and is sent to the solar heat collector 7 to absorb solar heat, hot water with increased temperature flows back to the ice water storage tank 6 from the upper part through a pipeline, and ice in the ice water storage tank is melted into liquid water in a direct contact mode. By the circulation operation, the ice in the ice water storage tank 6 is continuously or intermittently melted into liquid water as long as the heat obtained from the solar heat collector 7 is sufficient. If the ice water storage tank 6 is large enough, the ice storage capacity is larger and the ice-melt break time can be tolerated by the system.
In order to ensure the stable water amount in the ice water storage tank 6, a water supplementing system consisting of a water supplementing source 24, a filter 25 and a valve 20 is connected between the suction end of the cold water pump 10 and the valve 18. Under normal operating conditions, the valve 20 is closed and the water charging system is not engaged in operation, but is in a standby state at any time. When the system detects that the water needs to be replenished, the valve 20 is opened, and normal clean water from the water replenishing source 24 is sucked into the ice water storage tank 6 through the filter 25 by the cold water pump 10, so that the water amount in the system is kept constant. Or as mentioned above, when extreme weather occurs, in which the solar ice melting interruption time is too long, the valve 20 may be opened to replace the solid ice in the ice water storage tank 6 by supplementing water, so as to maintain the continuous and stable operation of the ice source heat pump system. The water supply source 24 may be tap water, surface water, well water, reclaimed water, etc., and the filter 25 is used for filtering and treating impurity contaminants that may exist in the water supply source 24. This emergency treatment method does not cause a significant increase in water consumption costs, since days of continuous rainy extreme weather of several days are few throughout the year.
Because the high-density phase-change latent heat (which is 80 times of the sensible heat released when the water temperature changes by 1 ℃) of 334kJ/kg is released when the water is frozen, the ice-water storage tank 6 can maintain the continuous and stable heat supply operation of the ice-water source heat pump system for a long time only by storing liquid water with a small volume, so that the melting operation of solid ice in the ice-water storage tank 6 can be carried out discontinuously, and the solar thermal collector 7 is adopted as an ice-melting heat source to melt ice for the ice-water storage tank 6 discontinuously, which is a completely feasible scheme. Therefore, no matter how low winter environmental temperature has, ice source heat pump system can both continuous stable long-term heat supply operation, this makes this ice source heat pump system possess the ability of all-weather stable high-efficient operation under various climatic conditions, has thoroughly solved traditional water, ground source heat pump and can't the technological problem of operation under "near freezing point" weather or "cold accumulation" condition.

The cooling water circulation at this time is a cooling water circulation of a general central air conditioning system, and the condensation heat generated in the condenser 1a of the heat pump main unit 1 in the operation for cooling is transferred to the cooling tower 4 through the cooling water circulation and discharged to the atmosphere.
