The "eco Multi Heat Pump" is a heat pump system that reuses energy without waste. In simultaneous operation of cold and hot water, both cold and hot water can be extracted at the same time. The capacity per unit is in the 15 horsepower 60 kW class. The dedicated control system, eco Multi Link, manages up to 12 units in connected operation control, including unit control, rotation operation, circulation pumps, and sensors, providing total control (AW/WW/WHC types). In addition to simultaneous operation of cold and hot water, the AW/WW type features various operating modes to accommodate different load fluctuations. The WHC type is specifically designed for simultaneous low-temperature cold water (brine) and hot water, allowing for operation in low-temperature ranges. The WSR type is designed for simultaneous cold water and high-temperature water (80°C). We will propose the most suitable heat pump system from our four unique models based on your industry, region, thermal load, operating rate, and time conditions. Please feel free to consult with us. 【Features】 ■ Energy-saving ■ Reduction of carbon dioxide emissions ■ Cost-saving ■ Heat recovery and utilization of unused heat ■ Optimal system proposals through various operating modes *For more details, please refer to the catalog or feel free to contact us.

It goes without saying that energy is universal. However, energy changes form, becomes difficult to use, and ultimately is released into the atmosphere or the ocean. The energy we create should be utilized as much as possible until the end. Eco Multi Hipon reuses energy without waste, so it is ecological because it does not discard it.

"Water bath for sauna" - Bathtub filtration system - Cooling heat source system (chiller) - Pressure-type water level control ● Reasons to recommend a filtration system for the water bath The water bath has a low temperature, making it easy for dirt such as sweat and sebum to coagulate, resulting in cloudiness. Without a filtration system, the water will quickly become cloudy, necessitating frequent replacement and cleaning of the bathwater. This leads to increased labor for cleaning and higher water bills. The tap water temperature varies with the seasons. Even in standard regions, there can be a temperature variation from 9°C in winter to 30°C in summer. The equipment needed to keep the supply water cold and constant incurs significant initial costs, installation space requirements, and ongoing running costs, which is similar for cold water showers. The initial costs of installing a filtration system are not much different. When a filtration system is installed, it only needs to cool the water that has warmed up from bathing, so the actual running costs are relatively low. Additionally, since the water bill only requires replenishing the amount that evaporates or is lost from the body after initially filling the bath, it can also help reduce water costs.

• Filtration Equipment

Conventional heat pumps could not accommodate the water quality of baths, so they used to create high-temperature hot water with heat pumps and maintain the bath's temperature through a heat exchanger. The new product now allows for direct heating of the circulating water in the bath through a combination of a newly developed heat exchanger unit and a heat pump unit. With the realization of direct heating, it achieves energy-efficient operation, and since a buffer tank and circulation pump are no longer necessary, it can be introduced at a lower cost and in a more compact form compared to conventional systems.

During disasters, the temporary baths provided by the Self-Defense Forces are well-known, but since they are limited in number, it is not guaranteed that everyone will be able to take a bath. Therefore, a disaster prevention bath set has been released by Hoshino General Trading, a specialized trading company in disaster prevention projects. This set includes our circulating filtration device, Bathtime 24, as well as a one-touch tent, a round assembly water tank that serves as a bathtub, and a 5.0 kVA gasoline generator. You might be concerned that if too many people use the bath, it will become dirty and require a large amount of water, but there is no need to worry. Bathtime 24 circulates and filters the water in the bathtub, so you can use it with just about 1 ton of water prepared initially. Additionally, chlorine tablets are included in the set, allowing for proper hygiene management. Furthermore, it can be stored more compactly and at a lower price than conventional products. The disaster prevention bath set comes with two tents: one for changing and one for bathing. The changing room tent has a privacy curtain that prevents visibility from the entrance, ensuring that women can use it with peace of mind.

A system specialized for individual outdoor hot springs. Generally, outdoor hot springs experience a decrease in water temperature due to heat dissipation. In this case, it was predicted that the water temperature would drop by 3 degrees in one hour, so we proposed a system that efficiently maintains the temperature while also incorporating filtration functions. Although it uses a "heat exchanger method," it combines a heat exchanger with a dedicated heat source unit and utilizes a compact home filtration device suitable for the bathtub's capacity. By controlling the dedicated heat source unit and the small filtration device in tandem, it creates a very compact system that eliminates the need for large water heating equipment, unnecessary pumps, and expansion tanks. This system not only keeps the water clean at all times but also maintains a comfortable temperature without cooling down.

●Heat recovery type heat pumps are attracting attention as alternatives to boilers and chillers because they can efficiently utilize both waste heat and cold heat that would otherwise be discarded. Government subsidy policies are also beginning to improve. ●There are two types of heat recovery type heat pumps: ・ Heat recovery type heat pump A type that recovers heat from industrial wastewater or hot spring discharge for heating or hot water supply. ・ Simultaneous cooling and heating heat pump A type that can efficiently supply both cooling and heating when both are needed simultaneously, such as in production processes or for air conditioning and hot water supply. ●While simultaneous cooling and heating heat pumps have significant advantages, building the system requires experience and know-how. Please make use of our expertise.

Are you managing a hot spring with a free-flowing source, but not draining the lukewarm hot spring water as it is? It's a bathing facility, but are you carelessly draining large amounts of lukewarm bathwater? That wastewater still has value! You might be able to reuse the heat with a heat pump system! By extracting heat from the lukewarm hot spring to warm the source or by capturing heat from the water being discarded to assist with the facility's hot water supply, the eco multi-heat pump reuses energy without waste. Not discarding means energy savings. Not discarding means reduced running costs. Not discarding means being eco-friendly.

The "eco Multi Heat Pump" is a heat pump system that reuses energy without waste. It is recommended for those struggling with insufficient cooling capacity of cooling towers due to extreme heat. Many are currently relying on well water or municipal water, but managing this is quite challenging. While they would like to resolve the issue, it's only a short-term problem during the summer, so they cannot justify investing in equipment solely to address the capacity shortfall... Good news for such customers: consider the eco Multi Heat Pump, which can solve the cooling capacity shortage and save energy.

■ Air-cooled simultaneous extraction type (AW-F) While maximizing the use of exhaust heat, it supports both cooling-only and heating-only load time zones with six operating modes. We propose the best energy-saving system. In factories and facilities using air-cooled chillers, the warm air discharged from the air heat exchanger is like wasting energy. Discharging at temperatures higher than the cooling tower or supply water temperature also wastes energy. By effectively recovering heat, energy savings and cost reduction can be achieved.
