Detailed Description
In order to make the technical solution of the present utility model better understood by those skilled in the art, the technical solution of the present utility model will be further described below by means of specific embodiments in combination with the accompanying drawings of the specification.
As shown in fig. 1, a waste heat utilization system with a surface cooling and dehumidifying function includes:
A water circulation heat pump 6 for generating cold water and hot water;
The surface cooler 3 is communicated with a cold water path of the water circulation heat pump 6;
and the heater 7 is communicated with the hot water path of the water circulation heat pump 6.
The surface cooler 3 and the water circulation heat pump 6 form cold water circulation through a cold water return pipe 4 and a cold water inlet pipe 9.
The heater 7 and the water circulation heat pump 6 form a hot water circulation through the hot water return pipe 8 and the hot water inlet pipe 10.
The surface cooler 3 and the heater 7 are both arranged in the box body 2, and the surface cooler 3 is arranged at the fresh air inlet end; the heater 7 is arranged behind the water baffle 9, namely on one side of the water baffle close to the air outlet end.
The surface cooler 3 is provided with a water baffle 5 at one end close to the heater 7.
The water pan 1 is arranged below the surface cooler 3 and the water baffle 5.
The inner bottom surface of the water receiving disc 1 is a conical surface, the lowest point is communicated with a drain pipe, and the drain pipe extends out of the box body 2.
The four corners of the box body 2 are provided with supporting feet with adjustable heights.
The working process of the utility model comprises the following steps:
The surface cooling dehumidification heating device adopts heat energy generated by a surface cooling dehumidification heat pump unit to preheat dehumidified cold air, specifically, cold water and hot water (cold quantity and heat quantity) are generated simultaneously when the water circulation heat pump unit operates in use, and the cold water is circulated into a surface cooler in the equipment through a hot water connecting pipe; meanwhile, hot water circularly enters a heater in the equipment through a hot water connecting pipe; after the fresh air enters the box body, the temperature of the fresh air is reduced through the surface cooler, water at the dew point temperature is separated out, and the separated water flows along the water baffle when the air passes through the water baffle, such as in the bottom water receiving disc; the dry air (relatively dry) with water separated out from the other side passes through the heater, and the temperature rises to remove the box body.
When the combined use is carried out, the surface cooling dehumidification heating scheme is required to be arranged in front of heating, so that the gas exhausted by the 2 boxes is subjected to secondary heating to meet the use requirement.
The original surface cooling dehumidification scheme only uses cold water (cold quantity) provided in the heat pump, and heat is discharged outdoors through the fan and the heat exchanger, so that a great amount of energy is wasted, and meanwhile, the dehumidified air has lower temperature and needs secondary heating; the utility model provides a new surface cooling dehumidification heating scheme, solves the problem of energy waste of surface cooling dehumidification, improves the economic benefit of equipment and reduces the energy consumption of the equipment.
