RBHG-180G

Categories：HEAT PUMP - Special high-temperature drying heat pump

Introduction：The high-temperature heat pump green drying machine utilizes heat pump technology. It can absorb the high-temperature and high-humidity exhaust gas emitted after drying linen through the evaporator of the heat pump. Then, the refrigerant is pressurized by the compressor to increase the temperature, and the heated air is passed through the condenser of the heat pump and enters the drum. Since the consumed electric energy is only for maintaining the circulation of the refrigerant and continuously transferring heat, it can obtain a greater amount of heat output with a smaller input of electric energy.

Traditional Washer-Dryer Working Principle & Energy Consumption

Current Energy Analysis: Most laundry industrial parks currently use gas-fired boilers to supply steam to the on-site laundry plants. However, natural gas prices continue to rise, and the drying and washing equipment used by these plants generally lacks heat recovery systems. As a result, energy costs remain persistently high.

Traditional washer-dryer working principle and energy consumption

[Diagram: Traditional dryer steam piping — steam pipes, condenser, drying equipment, exhaust gas 50~80℃ waste heat]

Working Principle: Most traditional dryers use boilers to generate steam as the thermal medium. Steam is piped to each dryer, where a heat exchanger converts the steam energy into hot air (100~120℃) that is fed into the dryer drum. The exhaust air discharged after drying linen still reaches 50~80℃, wasting a significant amount of thermal energy.

Using air-source or water-source high-temperature heat pumps to produce 75℃ hot water injected directly into washing machines saves energy and boosts productivity.

Using high-temperature steam heat pumps to recover exhaust waste heat as a heat source for steam production — energy-efficient and cost-effective.

[Schematic: Heat pump cycle — compressor, condenser, expansion valve, evaporator, with temperature annotations at each point]

Energy-Saving Principle: The high-temperature heat pump green dryer uses heat pump technology to fully absorb heat from the high-temperature, high-humidity exhaust discharged after drying linen. The heat is absorbed through the evaporator, then the refrigerant is pressurized and temperature-boosted by the compressor, and the condenser heats the air entering the drum. Since the electrical energy consumed only maintains the refrigerant circulation — a continuous heat transfer process — a small electrical input yields a large heat output.

Zhongshengneng Green Heat Core — Super Steam Replacement Savings

To reduce energy costs, many laundry plants locate next to power plants where steam is generally cheaper, typically around 220~260 CNY/ton. If a laundry plant mainly operates during the day, electricity rates can reach 0.9 CNY/kWh, which limits the savings from a pure heat pump dryer. To address this, Zhongshengneng introduced the Green Heat Core washer-dryer, which saves significant costs even when steam prices are low.

[Green Heat Core dual-energy heat pump schematic — steam + heat pump composite heating]

Energy-Saving Principle: The hot air entering the drum is heated in two stages: the low-temperature stage by the heat pump and the high-temperature stage by steam. According to heat pump principles, the smaller the difference between condensation and evaporation temperatures, the higher the energy efficiency. Heating the low-temperature stage keeps the condensation temperature low, while the addition of steam heat raises the exhaust temperature, which in turn raises the evaporation temperature. Therefore, the heat pump's energy efficiency is very high when heating the low-temperature stage — COP can reach 5.0, equivalent to producing 1 ton of steam using only 144 kWh. At 0.9 CNY/kWh, that's just 130 CNY/ton of steam, saving 110 CNY/ton compared to power plant steam (at 240 CNY/ton).

For example: Air entering the drum is heated from 20℃ to 120℃ (a 100℃ rise), where 20℃~90℃ is heated by the heat pump (70℃ rise) and 90℃~120℃ by steam (30℃ rise). Additionally, the dual-energy green dryer requires less compressor power, reducing equipment cost.

Zhongshengneng Heat Pump Washer-Dryer vs. Standard Steam Dryer — Investment Analysis

Category	Zhongshengneng Heat Pump Washer-Dryer	Standard Steam-Heated Dryer
Energy Cost (drying 1 kg dry linen, 45% moisture)	0.28 kWh, energy cost = 0.9 × 0.28 = 0.252 CNY (incl. drum fan power)	1.1 kg steam + 0.1 kWh power, energy cost = 0.486 CNY
Daily Energy Cost 12h operation, 900 kg dried	227 CNY	437 CNY
Daily Savings	437 − 227 = 210 CNY
Environmental Cost	Electricity only — zero pollution, zero emissions, no site restrictions	Power plant steam is expensive; gas boiler requires boiler room space, dedicated staff, and annual inspection
Initial Equipment Investment	125,800 CNY/unit — only requires power connection and exhaust vent	Main unit 35,000 + boiler piping allocation 30,000 = 65,000 CNY/unit total
Economic Benefit	Save 210 CNY/day, 6,300 CNY/month, 75,600 CNY/year; payback in 1.7 years for replacement, under 1 year for new purchase

Based on case studies: Zhongshengneng high-temp heat pump green dryer uses no more than 0.3 kWh per kg of dry linen (at 45% moisture content).

How to Obtain Lower Electricity Rates:

Most laundry plants operate mainly during daytime, using peak-rate electricity at 0.9~1.0 CNY/kWh. To secure lower rates even during daytime operation, Zhongshengneng partners with solar PV and energy storage investment companies — at no cost to the laundry plant — to provide electricity at rates below 0.7 CNY/kWh.

Multiple Cooperation Models — Choose What Fits & Start Your Green Transition

1. Lease-to-Own Financing Model

20% down payment, balance financed over 3 years

Zhongshengneng has signed strategic agreements with multiple financial leasing companies. Customers ordering Zhongshengneng high-temperature heat pump energy-saving dryers can use lease-to-own installment plans to easily acquire the equipment.

Equipment Price	20% Down Payment	3-Year Balance + Interest	Monthly Payment	Monthly Equipment Savings	Net Monthly Profit After Payment
125,800 CNY	25,160 CNY	100,640 CNY	2,980 CNY	5,940 CNY	2,680 CNY

This plan carries zero risk. After deducting the down payment and installments over 3 years, each unit earns 24,000 CNY/year net. After 3 years, the equipment is essentially free, and each unit continues to earn over 70,000 CNY/year. Actual figures subject to bank calculations.

2. Pure Leasing Model (Simplified Energy Management Contract)

Zhongshengneng provides 1 washer-dryer for side-by-side testing against your existing dryer. If the Zhongshengneng unit saves at least 2,980 CNY/month more than your current equipment, after deducting the lease fee you still save 2,520 CNY/month. You then pay a monthly rental for the energy-saving dryer. If business shrinks, you can return some equipment at any time; if business grows, you can purchase the leased units.

With this plan, the laundry facility pays nothing upfront — no credit check, zero risk, zero investment — and immediately saves substantial energy costs with Zhongshengneng's energy-saving dryer.

How to Calculate Hourly Savings of the Zhongshengneng Heat Pump Washer-Dryer

Hourly savings = Weight of linen dried per hour × (Current equipment energy cost per kg − Zhongshengneng heat pump energy cost per kg). Calculation steps:

1. Determine your energy prices
2. Calculate current equipment energy cost per kg of dry linen
3. Calculate Zhongshengneng heat pump washer-dryer energy cost per kg of dry linen

Heat Pump Hot Water — The Finishing Touch for Laundry Energy Savings

Laundry plants need hot water at appropriate temperatures for washing. Most facilities currently use steam to heat water, resulting in persistently high energy costs. How to further reduce energy expenses?
Using heat pump technology for hot water production + wastewater heat recovery can dramatically cut energy costs.
