Embodiment Construction

[0017] The cooling method and cooling tower for air conditioning placed in the underground project, the principle of its structure is shown in Figure 1, and the cooling tower cools the condenser of the refrigeration heat pump. The cooling water of the heat pump enters the evaporator to cool down, and the condenser of the cooling tower sprays circulating water, and the air is introduced to take away the condensation heat through air cooling, so as to achieve the purpose of cooling the cooling water of the air-conditioning and refrigeration equipment in the project.

[0018] For example: the air-cooled condenser designed with a cooling capacity of 100kw adopts the water spray method, and the consumption of spray water only needs 40-80KG per hour, and the circulating water pool is used, and the pool water can be sprayed circularly, especially in the form of mist spray, and the air outlet It leads to the ground; as long as there is an air outlet, the air-cooled condenser can take a...

Abstract

The invention relates to an underground construction use cooling method which cools off the underground construction by using active central air-conditioner and hot water of water-cooled condenser of dehumidifier in heat pump evaporation manner, i.e. the heat pump evaporator (water-cooled evaporator) is connected to the water-cooled condenser of the active central air-conditioner in series, and hot water is cooled by air-cooled condenser after the water-cooled evaporator completes evaporation, and the air-cooled condenser is cooled in a water spray manner, and the air outlet of the air-cooled condenser is leaded to outside of the underground construction. The invention greatly changes current air conditioner cooling scheme, and is different from current scheme in concept and system realization. The invention can resolve the problems of excessive temperature and cooling difficulty.

Description

technical field [0001] The invention relates to a cooling method and device for underground engineering, in particular to a cooling method for an air conditioner in an underground engineering, and more specifically to a cooling method and a cooling device for an air conditioner condenser in an underground engineering. Background technique [0002] In the design of traditional underground protection projects, it is considered that the underground has constant temperature conditions, and generally no special design for air conditioning is given; with the expansion of the scale of development and utilization of underground engineering areas, due to the increase in the use of electrical appliances and communication equipment, the temperature and humidity of underground engineering are lower in summer. With the increase, if it is not handled properly, the air temperature of the underground project will inevitably exceed the requirements of the index, ma...
