01/High temperature press energy-saving solution (digital vortex water curtain unit)

The position of the external unit is limited, and the temperature in the area is too high, resulting in short circulation of the compressor exhaust, which affects the normal operation of the compressor. Therefore, a water curtain is designed to be installed at the suction port of the compressor to create a water curtain at the suction point, thereby reducing the temperature at the inlet.

The municipal water is discharged onto the water curtain, which can save 5% of energy consumption except for the electricity used by the water pump;

Recycling equipment condensate water to the water curtain can save 15% energy consumption;

Automatic control, no need for manual operation;

Addressing customer pain points

1、 Common adverse factors affecting the temperature of the internal unit:

The installation location of outdoor units is limited, with poor ventilation and heat dissipation, which affects refrigeration;

Such as poor ventilation of the unit, limited heat dissipation space, etc.

The high temperature of the weather reaches or exceeds the design working conditions of the unit, resulting in high exhaust temperature and high condensation temperature of the unit,

The cooling capacity has significantly decreased, and the internal unit temperature does not meet the standard.

2、 Insufficient matching of design deviation units

The pipeline length is long and the pressure drop increases. Insufficient consideration has led to a smaller unit configuration;

Due to cost considerations during design calculations, the system's cooling capacity was not sufficient.

3、 The adverse effect of water spraying spray on external condenser is solved.

Long term spray spray will form scale on the surface of condenser, affecting heat dissipation and service life

02/Winter Unit Thermal Energy Utilization Plan

Addressing customer pain points:

The installation environment of the external unit is harsh, and the pipeline of the external unit is too long, which makes it impossible to install the external unit;

The problem of low outdoor air temperature in winter in the north, and the compressor not starting due to low pressure;

Recycling hot air through air ducts for reuse, reducing indoor air conditioning usage, and achieving energy conservation and consumption reduction;

Technical principle explanation:

The compressor unit is placed indoors, and the heat from the plate heat exchanger inside the unit is taken away by circulating water through a water pump, thereby achieving the purpose of cooling the cold chain equipment in the store;

Summer mode: High temperature condensed water is circulated to the outdoor water-cooled dry cooler through a water pump, dissipating heat outdoors to achieve the purpose of condensation;

Winter mode: When the outdoor pressure and temperature reach the set values, the outdoor circulation is turned off, and the heat is dissipated into the indoor environment through its internal water-cooled air duct, keeping the indoor environment at a comfortable temperature, saving the frequency of air conditioning use, and achieving the goal of energy conservation and consumption reduction.

03/Intelligent IoT remote monitoring technology

Pain points of cold chain equipment in convenience stores:

1. Cold chain equipment has high technological content and requires professional personnel for inspection. The more stores there are, the more personnel there will be. There is a shortage of professional personnel, a long training period, and high costs;

2. Cold chain equipment is a major energy consumer in convenience stores and one of the main operating costs, which cannot be effectively controlled;

3. The stable use of cold chain equipment is related to food hygiene and safety, and is one of the main risks in the fresh food business of convenience stores, which cannot be taken lightly;

4. The temperature of cold chain equipment does not meet the standard or malfunctions, which increases the damage and operating costs of convenience stores.

Adopting a complete set of electronic expansion valves, intelligent controllers, and remote monitoring

Benchmarking analysis of energy-saving data for electronic expansion valve+frequency conversion unit:

The power consumption data of 711 store (thermal expansion valve+Emerson digital vortex) using the same refrigeration equipment in the same area is as follows (July 25th, 2024- August 24th)

Conclusion: By comparing monthly electricity consumption, choosing the scheme of variable frequency unit+electronic expansion valve can save 29.2% energy in convenience stores.

05/Heating control scheme for condensation point of glass door

Working principle and advantages:

The dew point heating control technology for glass doors can accurately measure indoor temperature and humidity, predict dew point temperature, and automatically control output status according to the set range.

It can prevent condensation on the glass door of the refrigerator and save heating energy.

This technology ensures that the electric heating of the glass door starts running when the humidity is relatively high, and when the humidity is below the set value, the electric heating of the glass door is turned off;

By applying this technology, the average power consumption of glass doors can be reduced by over 70% per year;
