Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] like figure 1 As shown, the heating system for recovery of waste heat in the laundry room proposed by the present invention includes an ironing exhaust gas recovery unit 1 , a drying exhaust gas recovery unit 2 and auxiliary heating equipment 3 . The ironing exhaust gas recovery unit 1 is used to recover the heat of the ironing exhaust gas to generate high-temperature steam, and generate cold air for laundry equipment and improve the working environment. Drying exhaust gas recovery unit 2 is used to recover the heat of drying exhaust gas to generate high-temperature steam. Auxiliary heating equipment 3 utilizes solar energy and electric energy to supplement heat when steam heat supply is insufficient.
[0029] The ironing exhaust gas recovery unit 1 is mainly composed of a conventional heat pump unit 11 , a high temperature heat pump unit 12 , ...

The invention discloses a heating system and method for waste heat recovery of a laundry room. The system comprises an ironing exhaust gas recovery assembling unit, a drying exhaust gas recovery assembling unit and auxiliary heating equipment. The drying exhaust gas heat is discharged into the atmosphere after the drying exhaust gas heat is recovered, and water from a water tank passes through thedrying exhaust gas recovery assembling unit and enters into a flash evaporator. The ironing exhaust gas is discharged indoors to maintain the temperature of a workshop after staged cooling is conducted on the ironing exhaust gas; the water from the water tank is heated sequentially and sent to the flash evaporator. The heating system and method for the waste heat recovery of the laundry room canimprove working environments while provide high temperature steam and hot water to replace heat using demands of existing boilers, not only is waste of waste heat resources prevented, but also energyusing rate is improved, and meanwhile operation cost is reduced.
Description
technical field [0001] The invention relates to household appliances, in particular to a heating system and method for recovering waste heat from a laundry room. Background technique [0002] At present, except for large-scale hotels and hospitals setting up laundry rooms, service industries such as small and medium-sized hotels outsource clothing and textiles to professional laundry rooms. Professional laundries have larger laundry volumes, so have more heat demand and waste heat discharge. There are three types of equipment necessary for a laundry room: washer, dryer, and ironing machine. Taking ironing as an example, it needs steam at about 120°C, and emits high-temperature and high-humidity gas at 70-80°C and 90°C Condensation water or so. Most of the existing laundry rooms discharge waste heat directly, which not only causes waste of energy and thermal pollution of the environment, but also forms a high-temperature and high-humidity working environment that is not con...
