1. Project Overview

The proposed **30-ton heat pump hot water system** is designed to meet the daily hot water demands of your hotel with high energy efficiency and reliability. The system utilizes a **30P heat pump unit** paired with a **30-ton insulated water tank**, ensuring stable hot water supply while minimizing operational costs.  

---

2. System Working Principle

The heat pump operates on the **reverse Carnot cycle**, transferring ambient heat energy to water through four stages:  

- Evaporation: Ambient air is drawn into the evaporator, where refrigerant absorbs heat and vaporizes.  

- Compression: The compressor pressurizes the vaporized refrigerant, raising its temperature.  

- Condensation: High-temperature refrigerant releases heat to the water in the storage tank via a heat exchanger.  

- Expansion: The refrigerant passes through an expansion valve, cooling and restarting the cycle.  

**Key Advantages**:  

- COP (Coefficient of Performance): 3.8–4.2 (1 unit of electricity generates 3.8–4.2 units of heat).  

- Eco-friendly: Zero direct carbon emissions.  

- 24/7 Operation: Stable performance in ambient temperatures of 10°C to 45°C.
