Product Details

Product introduction

Air cooling (hot) water units can be divided into single cooling and heat pump two types according to the function. Heat pump air cooling unit with refrigeration and heating functions all in one, can not only realize cooling in summer and heating in winter.It is widely used in the area where in winter there is heating needs and there is no place for air conditioning, heating boiler and heating network. It has become the preferred equipment in HVAC engineering solutions. The unit adopts modular design, with the cooling capacity of 390 kW, 520 kW, 780 kW, 910 kW and 1040 kW, and the maximum cooling capacity of 1040KW*4=4160KW. After optimized design and careful matching, advanced control technology is integrated to ensure the reliability and performance of the product. This series of units can be combined with fan coil units, cabinet air handlers, ceiling air processors, fresh air units, combined air processors and other air-conditioning terminal equipment to form a semi-centralized or centralized central air-conditioning system. This series of unit without having to build room, can be directly placed on the roof of the buildings, the skirt building platform or on the ground, which is safe and clean. There is no cooling water system,cooling towers, cooling water pump, and the corresponding pipe system and many other accessories. Simple structure, convenient maintenance make it especially suitable for water shortage area.

Working principle of the unit

Air-cooled modular air conditioning unit is an integrated central air conditioning equipment with air as the cold (hot) source, water as the cooling (hot) medium and cold (hot) source. Modular air cooling (hot) water unit, realize heating in winter through consumption of part of the electrical energy, by drawing out the low-grade energy in the air to supply heating; In Summer, it draws the indoor heat out to release into the air to achieve the purpose of air cooling.

Products Description

Compressor

The unit adopts the world famous brand compressor, which can realize the efficient operation of the full pressure ratio and obtain better comprehensive operation efficiency.

Title goes here.

Semi-Automatic PET Bottle Blowing Machine Bottle Making Machine Bottle Moulding Machine PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.

Electronic EEV

Precise adjustment of cooling capacity, more energy-saving operation. Adopt high-precision electronic expansion valve to ensure stable and efficient operation under all working conditions.

Water-side heat exchanger

The water-side heat exchanger adopts a new shell-and-tube heat exchanger with high efficiency, and the heat exchange tube is a high-efficiency copper tube with internal thread, which enhances the heat exchange efficiency between the water side and the refrigerant side, optimizes the pipeline layout and baffle design, ensures low water resistance and high efficiency, and has a large internal waterway flow area, which is not easy to block and scale, prolongs the cleaning cycle and ensures the long-term operation stability of the unit.

Condensing fan

Adopt high efficiency and low speed fan, low noise, and adopt fully sealed scroll compressor, with rubber shock absorber at the bottom as standard, which runs smoothly.

Installation Instructions

Unit hoisting

When lifting with a crane, handle it carefully. Use a flat belt or steel cable to bind the lifting steel pipe for lifting. There should be a pad at the contact between the steel cable and the machine to avoid injury to the equipment. The steel cable at the hook should be wound around the hook to avoid danger due to unbalanced weight.

Unit installation specification

The installation of the unit shall meet the following requirements: 1)Ensure that air inlet and exhaust are smooth; 2)Avoid being affected by dirty and corrosive airflow; 3)There should be room for outdoor unit maintenance; 4)The impact on the surrounding environment should be minimized; 5)Condensate and defrosting water should have drainage channels. 6)Unit installation refer to the recommended spacing to ensure smooth airflow. There should be no obstacles up there. If the top space is insufficient, install a curved air duct to direct the air far away to avoid short circuit and affect the unit performance.
