Problems solved by technology

Drying equipment generally adopts ironing machines, dryers, hand ironing machines, etc. that use steam as a heat source. The pressure of the steam (that is, exhausted steam) discharged from the drying equipment is generally 1.2 to 1.3kg / cm 2 Or so, the temperature is around 110-140°C, and it can no longer be used to dry clothes. It is often directly discharged into the sewer or sewage pool through the trap, causing a lot of waste of heat energy and high-temperature condensed water

Embodiment 1

[0021] Laundry rooms of star-rated hotels or guesthouses have a lot of clothes, bed sheets, and quilt covers to be washed with hot water for a long time and baked with steam. Dirty hot water after washing and exhausted steam after baking are usually directly discharged into the laundry room. In the trench inside the laundry room, the environment in the laundry room is humid and hot, which seriously corrodes the equipment and is unfavorable to the physical and mental health of employees; especially in summer, the temperature in the laundry room is as high as 40-50°C. On the one hand, the effect is not very good due to too much humidity.

[0022] Such as figure 1 As shown, the air source heat pump is installed in the laundry room, and the cold air absorbed by the heat pump is directly discharged into the laundry room from April to October every year to reduce the ambient temperature in the laundry room; every year from November to the next year In March, the cold air is dischar...

Abstract

The invention discloses an hot water production method complementary of air heat source and steam exhaust exhaust heat, is characterized by employing an air source heat pump to heat up tap water by temperature of 8-12 DEG C; recycling steam exhaust in washhouse to reheat up the hot water from the air source heat pump by temperature of 55-70 DEG C, and feeding the hot water into a hot water reservoir for standby. The steam exhaust itself is condensed to be condensation water with temperature of about 90 DEG C approximately and is feed into the water reservoir for standby. In addition condensation water used by dry cleaning apparatus and / or wiping stain bench in the washhouse is converged and feed into the water reservoir for standby. The invention can effectively use hot water from air heat and steam exhaust waste heat in washhouses of guesthouse or hotel, which can remarkably conserve energy and reduce cost.

Description

technical field [0001] The invention relates to a hot water production method, in particular to a hot water production method in which an air heat source and exhaust steam waste heat are complementary. Background technique [0002] High-rise buildings such as hotels and guesthouses are the largest households of building energy consumption, and they are also the largest households of concentrated consumption of sanitary hot water. The energy consumed for manufacturing sanitary hot water accounts for about 30% of the total energy consumption of hotels. Inventing an energy-saving and efficient large-scale sanitary hot water manufacturing method has far-reaching significance for the hotel industry to save energy, reduce emissions, and reduce operating costs. [0003] At present, the manufacturing methods of large-scale sanitary hot water mainly include the following: (1) using boiler steam to produce hot water intensively; (2) consuming fuel oil or gas, using lithium bromide dir...
