Closed Pressure Air Source Heat Pump Unit

Description:The air-source heat pump module of YIJIAREN water heating unit under pressure and consists mainly of three parts: the main unit and system accessories (integrated), a heating water tank, and a thermal storage tank. The system utilizes a compressor to transfer heat from the air to the water, maintaining a continuous cycle of the refrigerant. The heat pump consistently absorbs heat, efficiently transferring it to the closed water tank via a condenser. Through internal water circulation, each pressure module's water tank is filled with hot water.

Working Principle

Product configuration
1. Direct-Heating Pressurized Heat Pump Technology, Fast Heat Exchange

Pressurized heat pump units use the principle of Carnot cycle, achieving large temperature difference heat exchange, fully utilizing the abundant heat in the air, providing heat several times the electrical energy consumed, saving about 30% more than traditional heat pump system designs.

2. Modular Pressurized System, Significantly Lowering System Loss

Compared to conventional open heat pump systems, a modular pressurized heat pump system greatly reduces system loss such as heat loss from water tanks and power consumption of water pumps in the system transmission process, thus significantly reducing operating costs.

3. Modular Pressurized System, Constant Temperature and Pressure, Stable and Comfortable Water Supply

In non-pressurized systems, hot water is pressurized by a booster pump and cold water is pressurized by the municipal pipe network, making it impossible to maintain balance due to different pressure sources for hot and cold water. Also, open water tanks fill from the top, easily causing hot and cold water mixture in the tank, resulting in inconsistent temperature at the water usage end.

4. No Secondary Pollution, Water Tank Does Not Need Frequent Cleaning

Air energy water unit uses compartmental heat storage technology, with no coils inside the water tank, effectively resisting the growth of bacteria. With distributed water tank layout and dynamic water supply, it targets no water mixture, no scale, ensuring the cleanliness of the water tank and maintaining the quality of hot water.

5. Modular Combination, Flexible Installation

The modular pressurized water tank has a small footprint, low height, and light weight, can be tightly and seamlessly arranged in combination, adaptable to a variety of installation spaces. Standardized on-site construction is easy: system positioning, followed by connecting water, electricity, and water pipes, without the need for on-site refrigerant charging and welding, can be completed in a short time.

6. Multi-functional, Hot water, Bubble bath, Constant temperature swimming pool

The system can be equipped with multiple operating systems and can provide at least 5 concurrent water supplies. It can be used to connect to showers, bubble baths, constant temperature swimming pools.

7. Multi-energy Supporting System

Depending on energy conditions of different projects, it can carry multiple energy combination water systems such as "air energy module pressurized solar energy", "air energy module pressurized gas boiler", "air energy module pressurized electric boiler".

8. High System Integration, Enhancing Stability and Reliability

With a bright future, air energy heat pump has seen numerous product manufacturers flooding the market in just a few years. Aside from uneven product quality, most companies can only supply heat pump units, but rely on corresponding supporting manufacturers for water tanks, solenoid valves, electric heating systems, etc. This leads to poor system integration making later installation challenging, hence the industry saying: "30% depends on the product, 70% depends on the installation."

In contrast, commercial pressurized heat pump hot water systems have high integration, not only offering factory quality but also making later installation more convenient: After system positioning, only water and electricity need to be connected, there's no need for onsite refrigerant charging and welding. Unlike traditional heat pump systems with uncontrollable installation and construction quality, this system's strong integration ability makes it extremely stable and reliable.

YIJIAREN's "Direct Heating + Pressurized" air-energy heat pump system uses a closed-cycle pressure module water tank, which is well-insulated and has little heat loss. Together with the heat pump's design, it provides an energy-saving and comfortable hot water solution for premium hotels, guest houses, hospitals, gyms, health clubs, clubs, baby bathing and living studios, foot massage shops, etc.

Advantages

1. The water tanks are evenly distributed, uniformly pressurized to meet the structural load requirements of the building.

2. Both cold and hot water are sourced from the municipal pipeline, maintaining balanced pressure to avoid sudden temperature fluctuations.

3. Based on hotel accommodation characteristics, modularized hierarchical hot water supply allows for variable capacity supply, reducing partial electricity expenses.

4. Distributed water tank layout enables dynamic water supply without mixing or scaling.

5. Integrated accessories result in a nine-tenths product to one-tenth installation ratio, ensuring a more stable system.

6. Multiple operating systems can be configured to connect with hotel showers, soaking tubs, and temperature-controlled pools based on different requirements.

7. Lower operational costs: Pressurized air-source systems save around 30% in operational expenses compared to open-air systems (due to lower operational power and better insulation). The entire system operates automatically, eliminating the need for manual supervision, thus saving manpower and resources, equating to savings as wealth.

8. Lower maintenance costs: Pressurized water tanks come with magnesium rods to protect the tanks and undergo regular sterilization for better water quality, eliminating the need for booster pumps.
