Air source heat pumps are continually advancing as research and development drive innovations and new products. One notable development is the adoption of R290 refrigerant, which enhances the sustainability of this low-carbon heating option. This article explores what R290 refrigerant is, why it is gaining popularity in heat pumps, the benefits of   R290 heat pumps , and how they compare to alternatives like R32 heat pumps.     What is R290?     Commercially known as propane, R290 is a natural refrigerant widely used in air conditioning and refrigeration. Its use in air source heat pumps is growing, replacing other refrigerants. In heat pumps, R290 operates similarly to traditional refrigerants, undergoing cycles of liquid and vapor states to transfer latent heat from outdoor air into usable energy for central heating systems.   Why Choose an R290 Heat Pump?     Air source heat pumps  provide low-carbon heating, meeting the space heating...

  The  refrigeration compressor  is the core component of the air conditioning and refrigeration system, and the stability of its current directly affects the operational efficiency and stability of the entire system. However, in practical applications, the problem of unstable refrigeration compressor current occurs from time to time. In this paper, we will discuss the causes of this problem and propose corresponding solutions.   Failure causes 1, unstable supply voltage: when the industrial voltage is unstable, the current of the compressor will also fluctuate. The compressor needs a stable voltage to ensure normal operation when starting and running. 2, line load is too large: if the line of the power supply load is too large, it will lead to a higher line current, which in turn affects the stability of the compressor current. 3, condenser overheating: the condenser is used for heat dissipation, if its surface is covered with dust or debris, or internal failure, it...

  In the heat pump heating system, the volume calculation of the  buffer tank  is a key link, which is directly related to the stability and energy efficiency of the system. The following are several common buffer tank volume calculation methods:   1, based on the system stability of the amount of water required and the difference between the actual amount of water system calculation Calculate the amount of water required for system stability (M1): Formula: M1 = QT / (C△T) Where, Q for the heat pump unit heat production (unit: KW); T for the frost time (unit: seconds); C for the specific heat capacity of water, generally take 4.187 (unit: J / (kg - ℃)); △ T for the water supply temperature is allowed to drop the maximum value, usually take 3 ℃ (or adjusted according to actual needs). Calculate the actual amount of water in the system: For  underfloor heating systems , the actual water volume is equal to the water capacity per metre of the underfloor heating...

  Everyone desires powerful and efficient air comfort throughout the year, both in summer and winter. If you’re looking for a new central HVAC system for your home, consider a split system heat pump. These advanced products can provide the cooling you need during hot weather and can reverse the cycle to generate the necessary heat when temperatures drop.   A Split System Heat Pump Is Essentially an Air Conditioner   Most people are familiar with air conditioners. Whether you have a window unit or an extensive central system, you know that turning down the thermostat cools the house. This is because the refrigerant cycle inside the air conditioner removes heat from your home.     The primary difference between a  split system heat pump  and a regular air conditioner is the ability to reverse the refrigerant cycle. Instead of merely removing heat, a split system heat pump can bring heat back inside when the weather turns colder. This versatility gives ho...

  European heat pump sales have shown some volatility and complexity in the recent past, according to the latest market data. Data from the European Heat Pump Association (EHPA) shows that while the European heat pump market showed strong growth in 2022, with sales reaching an all-time high of 3 million units, up 38 per cent year-on-year, the market is entering 2023 with some challenges.   Specifically,  heat pump sales  in Europe's 14 major countries (which account for 90% of Europe's sales) were 2,639,500 units in 2023, a year-on-year decline of 4.5%, which is the first time in 10 years that sales have declined. Among them, Germany, an important country in the European heat pump market, saw its heat pump sales of 356,000 units in 2023, which, while growing by more than 50 per cent for the second consecutive year, fell sharply in the first quarter of 2024, with total sales of 46,000 units, compared with sales of 96,500 units during the same period of 2023, a drop of...

  As technology continues to advance, refrigeration equipment plays an increasingly vital role in both daily life and industrial processes. From homes and commercial establishments to industrial applications, the evolution of refrigeration technology has brought about significant changes. Let's explore the various types of equipment used in modern refrigeration systems. 1. Refrigerators and Freezers Household Refrigerators and Freezers : These are the most common refrigeration units found in homes. They use a vapor-compression cycle to maintain low temperatures, preserving food and other perishable items. Commercial Refrigerators and Freezers: Used in supermarkets, restaurants, and other commercial settings, these units are larger and more robust, designed to handle higher capacities and more frequent use. ​ 2. Air Conditioning Units Window Air Conditioners : These compact units are installed in windows and are ideal for cooling single rooms. They use a similar vapor-compression cy...
